This study was conducted to examine the inhabitation of wild birds at the World Cup Park and to offer the Park ecological management data. Land use md actual vegetation were examined to analyze the inhabitation of wild birds. Characteristics of bird communities were analyzed by dominance, density, diversity index and guild concept. You compare inhabitation before and after the Park was built. We classified the land use and actual vegetation into twenty-six types. Robinia pseudoacacia dominated the study area. Pyeonghwa Park and Nanji-cheon Park were simple-layer structures composed of alien woody species. The observed birds after the World Cup Park included 33 families 77 species, and 9,751 individuals. Among Wild Life types, the shrub and bush type was dominant. There were 26 species of resident birds, 20 species of summer visitors, 18 species of winter visitors, and 12 species of passage migrants. The following numbers of species and individuals were observed: in Hanul park, 38 species, 3,151 individuals; in Noul park, 45 species, 2,061 individuals; in Nanji-cheon park, 42 species, 2,742 individuals; in Pyeonghwa park, 29 species, 875 individuals; and in Maebongsan(Mt.) area, 35 species, 922 individuals. Species diversities for each area were as follows: Noul park, 2.613; Hanul park, 2,301; Nanji-cheon, 2.228; and Pyeonghwa park, 2,019; and each season: summer, 2.652; spring, 2.650: winter, 2.561; and autumn 2.176. The diversity of species increased from 1.135 in 1994 to 2.324 in 2001. We recommended that the park be differented into different ecological areas in order to encourage the appearance of wild birds at the World Cup Park. The management area was divided into three districts(conservation area, preservation and restoration area, use area). The conservation area was established to the west of a waste landfill and in the downstream area of NanJi-cheon, the preservation and restoration area was established in the midstream area of Nanji-cheon, and the use area was established in the buffer zone of Pyeonghwa Park and the Nanji pond greenspace.

The agricultural landscape is considered an important space to provide service functions, but the reality is that environmental and ecological problems are being reported in the creation of a facility horticulture complex. Therefore, this study was conducted to contribute to sustainable agriculture by creating a more eco-friendly facility horticultural complex. The elements of planning for eco-friendly development of the facility horticultural complex were derived from literature and expert surveys. The master plan and the bird's-eye view were then applied to the Saemangeum area by applying the planning elements. After analyzing the method of selecting and deploying input elements for improving functions, it was suggested that low-flow areas, wetlands, artificial storage facilities, green spaces, and waterways should be placed in harmony with the landscape and that the building-to-land ratio should be applied at 55%. The final design was prepared by applying the ecological service function improvement plan proposed by experts. The final bird's-eye view also reflected water purification facilities, connection of wetlands to waterways, packing of pitchers, and connection of green areas. The results of the research are expected to be used as basic data for policy and budget allocation for the eco-friendly creation of horticulture facilities and contribute to sustainable agriculture by contributing to national biodiversity and environmental preservation.

The purpose of this paper is to classify two study sites into the biotope types and investigate the landscape ecological characteristics of them. This will be available for the rural planning in the aspect of environmental preservation. The summaries of the result are as follows. 1) In the result of the area assessment in biotope groups, a dry field (32%) and a paddy field (28%) are more than 50%, but settlement space and water space are less than 10%. The result shows the land use condition of rural areas. 2) In the investigation result of elongation, running water spaces are higher than other biotope groups relatively, it is because they long shaped and 1-3m narrow. 3) In case of Fractal index analysis, residential spaces and cultivated lands are investigated to be lower in numerical value, it is because they have the definite borders and get simple in the border of landscape by human intervention. 4) In case of dispersion degree, the dry field has the highest value because they are located close by forests spread widely around study sites. It means that the land which is used by artificial purpose get more value rather than natural lands 5) In the connectivity analysis, a paddy field and a residential space appear the highest. It is because residence spaces spread intensively through roads and a paddy field, through streams. 6) In rural landscape, the diversity of landscape is investigated to be simple. A paddy field and a dry field contain small sized patches that have been divided by human intervention. Besides, there appear much different vegetation around waterways and farm-roads.

Near future dynamics of water qualities (nutrient concentration) of the Han River was predicted, based on a mathematical model representing the relationship between the nutrient concentration in th river wagter and environmental factors (population density, land-use types, rock compositions and nutrient accumulation) in the basin. The population density and land-use types were forecasted to change distinctly in the downstream area, especially in Seoul City area in 1985~1990 whereas any environmental factor was not expected to change its level significantly in both upstream and middle reaches areas. It was indicated by the model that the nutrients concentration in the up- and mid-streams would keep its level in future as it was, but it would increase drastially in the downstream area. For the preservation of the water qualities in the downstream at least to keep its level as it was in 1980, practical countermeasures were proposed, based on the assessment of the contribution of each environmental factor to the water qualities.

This study examined the changes of water quality in relation to distribution of hydrophytes, and the purification capacity of Zizania latifolia to improve the effluent from Munpyeong stream from March 1997 to December 1999. While the concentration of nitrogen and phosphorous in water were increased during the farming season, those decreased, during the streaming down to paddy and drainage areas. In investigated sites, the Z. latifolia was dominant community according to the development of the natural wetlands. Furthermore, it formed a large community owing to its high adaptability to environmental changes in the agriculture lands. In September, the leaves productivity of the Z. latifolia were 4,032g D.W/$m^2$and roots were 7,680gD.W/$m^2$. The purification capacity of the Z. latifolia for NH$_3$-N, $No_3$-N, and PO$_4$-P were 13.41, 17.07, and 4.58 respectively during 5 days. The results suggested that it needs to establish wetlands vegetated by hydrophytes to improve the water quality of the effluent from agricultural lands.

Wetland areas have characteristics of dynamic cycling of materials in relation to land and water. Although having great potential for providing unique natural environments, they are vulnurable to human land use activities and some places are in danger of being eliminated. This study had an objective of investigating vegetation changes in Ilwol reservoir to provide basic information for the preservation and ecological restoration of the wetland area. Wetland vegetation was investigated along with the site conditions which may affect the vegetation development. There were 10 vegetation types with various species composition. Humulus japonicus, Zizania latifolia, Phragmites japonica, Bidens frondosa, Typha orientalis, Scirpus tabernaemontari, Phragmites communis, Persicaria thunbergii were the major wetland plants found at the reservoir area. Precipitation and water level were the elements mostly affecting the distribution of the plants. Phragmites japonica was closest to the water front, followed by Zizania latifolia, Humulus japonicus and Bidens frondosa. Most plant zones were predominated by one or a few species.

In this manuscript, a review of the diversity of Chinese indigenous goat breeds according to data from body stature and appearance, chromosome group, blood proteins, DNA molecular markers (mitochondria DNA, random amplified polymorphic DNA, microsatellite DNA, major histocompatibility complex) has been introduced. All of these provide efficient tools for the diversity analysis of Chinese indigenous goat breeds and are very important for biodiversity conservation, restoration of declining goat breeds, the priority defining in Chinese indigenous goat breeds' protection and the selection of nature preservation zones. Many Chinese indigenous goat breeds with small population size in the isolated mountains or reservoir areas are verging the potential threat of extinction, effectively lost with the rapid destroying of ecological environment. On the other hand, as a result of the introduction of modern commercial goat breeds and shortage of effective conservation, some populations, such as Small-xiang goat and Tibetan goat decrease rapidly in number of sires. In the interests of the long-term future of the goat breeds in China, conservation of goat breeds' genetic resources should be considered urgently and some conservation measures should be adopted. In addition, the continuing development of molecular biology will further enhance conservation of diversity of Chinese indigenous goat breeds.

This study aims to, first, classify the approach system of utilizing national and local amenities into three groups: evaluation of the level of the amenity, evaluation of the value of amenity resources, and utilization of amenity resources. Secondly, the study aims to derive an evaluation index which is required according to the approach system. As for a strategy of utilizing amenities, the self-diagnosis based on the evaluation of the level of local amenities is required. In this study, three sectors, ten items and 43 detailed items have been derived though specialists, FGIs(Focus Group Interview), and the cases within and outside of the country. In the survey with specialists, a unit-space key index which can be used in accordance with the unit-space characteristics(such as urban and rural area, fishing villages, mountain villages, and littoral areas), environmental area, important index and optional index have been derived. As for the evaluation index which is needed for the development of typical local amenities resources, 14 detailed evaluation indexes from three sectors have been derived. These have been classified again into six key indexes, six important indexes and two optional indexes. In the evaluation index of amenity resources, natural and environmental value-such as ecological value of preservation, uniqueness of aesthetic landscape and ecological value of restoration-historic and cultural value of preservation and individuality of the resources, and aesthetic and cultural values are derived as being important. As for utilization of amenity resources, 15 items from three sectors-such as reservation, restoration, intentional use, and industrial use-have been derived. Also, through a survey with specialists, key indexes and important indexes were derived by unit-space. As a result, in urban areas, seven items-including creative development of space, aesthetic landscape control and development of cultural contents-have been derived as key indexes; in rural areas, mountain villages, fishing villages and littoral areas, eight items-including brand of region, brand of the products, and brand of tourism resources-have been derived. In environmental areas, six items-including reservation of natural resources, historic and cultural heritage, and restoration of ecosystem-have been derived. Indexes derived from this study can be utilized in order to establish a strategy for amenity plans and an implementation strategy, but can be readjusted, allowing for various regional characteristics. It is, thus, advisable that local governments selectively utilize indexes according to regional characteristics or newly develop them for the maximum utilization of regional amenities.

Reviewing the trend of land use in urban cultivated land, the large part of land has been changed into the high-profit cultivated land of green houses or the developing areas. So, its percent of cultivated land in land use comparing to the other types of cultivated land would get far higher. Therefore, this study aims to identify the characteristics of landscape ecological pattern in the cultivated land of green houses and to find its alternatives for management, which would be a basis of regional planning and management in terms of space and time. The cultivated land of green houses, whose its area reaches 19.3ha, in Seoul are mainly dispersed on the south eastern part of Seoul and its area is larger than the other types of cultivated lands. According to the result of shape index analysis, its perimeters were very simple. Also, Analyzing the first three major neighboring land use to the cultivated land of green houses, the most frequent biotope types of neighboring land use to the cultivated land of green houses were that transportation facility represented 60%, forest, 43%, the other types of cultivated land, 36%, and residential area, 33%. The cause why the percent of transportation facility was higher in the neigh-boring land use types was assumed for the production and distribution of crops. On the basis of the result of landscape ecological pattern analysis, the cultivated land would be managed and contributed to enhance biodiversity and urban environment preservation.

The researcher noted the fact that wetland users are more and more diversified while people are more conscious of their ecological importance. Wetlands tend to be very sensitive in ecological terms, and therefore, they can hardly accommodate their users' needs indefinitely. With such basic perception in mind, the purpose of this study was to survey wetland users' eco-consciousness, determine their traits, analyze the corelation between their traits and preferences of wetland amenities, and thereby, provide the data useful to planning of an effective wetland management policy. To this end, the researcher sampled nation's largest wetland, Upo Marsh located in Changnyeong for a questionnaire survey. Wetland users' eco-consciousness was measured, using Dunlap's NEP (New Ecological Paradigm) approved by many researchers. Wetland users' preferences of the wetland amenities were measured, centered around 11 amenity types observed commonly at the domestic wetlands. As a result of the survey conducted in October, 2012, a total of 228 effective samples were acquired. Wetland users' eco-consciousness was higher than normal, scoring 3.45 on the 5-point scale consisting of 5 sub-scales. In particular, users were more conscious of 'the possibility of an eco-crisis,' while being less conscious of 'ejection of exemptionalism.' As a result of classifying the users into 3 sub-groups in reference to their eco-consciousness and analyzing their preferences of amenities comparatively, significant differences were found in all 3 sub-areas. In particular, the sub-group most eco-conscious tended to prefer the learning amenities, but the least eco-conscious sub-group tended to prefer the utilities. As a result of the post-hoc test, it was found that most and normal eco-conscious sub-groups were more or less homogeneous, while the least eco-conscious sub-group was significantly different from the former 2 sub-groups in terms of eco-consciousness. As the wetland users were found to be diversified in terms of their eco-consciousness, it is necessary to plan the wetland management policies in consideration of such differences. However, it is perceived that the wetland amenities need to be built to meet the more eco-conscious users.
