The purpose of this study is to derive policy suggestions and new orientations for biotope mapping in Korea from a review of case studies on the classification of biotope typesin Germany. This study was conducted in the following manner: First, the related literature and data on biotopes in Germany was collected. Second, the representative examples at the provincial government level and urban and residential areas were selected. Finally, the characteristics of biotope types, biotope classification systems, and biotope classification criteria were reviewed. The results of reviewing the case examples in Germany are as follows: First, the biotope types at the provincial government level were composed of patterns which existed mostly in natural areas and the corresponding areas of their conditions. Those in urban and residential areas were made up of patterns which were distributed in urban areas and their peripheries. Second, the biotope classification systems at the provincial government level consisted of three steps:large, medium and small. Those in urban and residential areas were made up of two steps: medium and small. However, it is strongly recommended to introduce the biotope classification system composed of three steps. Third, the biotope classification criteria at the provincial government level considered ecological factors and anthropogenic factors except land use forms. Those in urban and residential areas reflected mostly anthropogenic factors and ecological factors. In conclusion, this study suggests that future biotope surveys and mapping in Korea should be investigated not only in urban areas but also in natural and semi-natural areas. In addition, a specified biotope type classification system should be established in Korea.

The focus of this study is the promotion of green area volumes and their naturalness, water circulation system, decline of entropy, creation of biological habitats and linkage of separated urban green space. Re-presentative urban biotope survey sites were categorized as urban biotope, semi-natural biotope, and natural forest. In the urban biotope, a residential biotope was constructed near the Han river and in mountain areas. The green-area ratio at the housing complex was about 25%. GVZ(Grunvolumenzahl) was 0.35m$^3$/m$^2$ at the 5∼10-story housing complex, and 1.53m$^3$/m$^2$ over the 11-story. As for the green-area structure of the housing complex, canopy layer, understory layer, and shrub layer were not differentiated and the green-area volume was not high enough. The green-area ratio of school areas as a public area biotope was 5∼20%. GVZ was 1.12m$^3$/m$^2$ at Myungduk High School, and 1.78m$^3$/m$^2$ at Jeonggok Elementary School. In order to convert the urban biotope into an ecological area, green areas around the buildings should be connected to urban buffer green areas, and multi-layer structures should be established with natural plant species. In the semi-natural biotope, neighbor parks were created park in the vicinity of the natural forests. GVZ was 0.28m$^3$/m$^2$, and plantation was established with single layer structure and was definitely insufficient for the area. The urban buffer green areas have been established in strip corridors with the width of 20∼123m. In those areas, GVZ was 0.16∼0.27m$^3$/m$^2$ and had a deficient canopy layer, understory layer, and shrub layer. Soil conditions were not favorable for tree growth. In the natural biotope, GVZ of the plantation was 1.03∼1.5m$^3$/m$^2$ but the high crown closure of this area reduces the chance of species change and succession. GVZ of natural forest was 2.53∼2.57m$^3$/m$^2$. It is desirable to plant diverse plants and the natural forest should be succeeded by broad-leaf deciduous tree species. To improve the value of biotope at Kangseo-Gu, building height needs to be limited to reduce the environmental deterioration in the city. In order to maintain the water circulation system, water-permeable material is recommened when the urban surface areas are paved. The establishment of a water circulation system will improve ground water levels, soil moisture, water quality, and habitats. In order to improve biological diversity, it is desirable to have multi-layer structures in urban green areas with native species.

One of the major environmental issues Japanese cities is now facing with is the conservation of seminatural landscapes for the restoration of ecological integrity of urban areas. The satoyama landscape, which includes coppice woodlands, agricultural areas and rural settlements, is seen as an indispensable semi-natural landscape, formed as a result of man-nature interaction. However, because of the loss of the economic viability they are now abandoned and in the process of losing their ecological values. Today a number of local municipalities as well as NPO groups are involved in the conservation projects of these landscapes. Although satoyama landscapes are commonly believed to have maintained their character over the years, historical studies have revealed that these landscapes have experienced constant and dynamic changes due to a variation in human impacts. It is therefore understood that the conservation projects on satoyama landscapes should not intend to restore their past condition, but should wet the goal of maintaining their dynamic character by promoting ecological roles which the landscapes may play in the contemporary world. EXPO2005 project in Aichi Prefecture is a good example of a development project underway on satoyama landscapes which intend to conserve the landscapes by stimulating contemporary ecological for them. In EXPO2005 project the key issue was the conservation of semi-natural landscapes formed by constant and intensive human impacts over the centuries and thus allowing endemic and endangered species to be accommodated. The planning team proposed a scheme to restore economic viability of satoyama landscapes. The scheme involves re-introducing intensive human impacts through a new management system with an innovative technology. This may restore the economic viability of lumbers provided form satoyama woodlands. EXPO2005 is understood as a model case which stimulates contemporary ecological functions of satoyama landscapes by applying innovative planning concepts.

범죄현장조사에 사용되는 인체에 유해할 수 있는 일반분말에 대한 대체수단으로 천연분말(오징어 먹물분말, 청대분말, 쌀분말)을 이용하여 비 다공성표면(유리, 플라스틱, 타일)상의 잠재지문을 현출(가시화)하였다. 현출된 잠재지문을 Automatic Fingerprint Identification System (AFIS)으로 분석한 특징점의 수를 흑색분말을 사용한 결과 특징점 수와 비교하였으며 또한 객관적이고 계량적인 평가방법의 개발을 위하여 각 분말로 가시화된 지문의 이미지를 농도계 이미지분석(densitometric image analysis)을 이용한 결과 값인 융선 피크의 면적값을 비교하였다. 천연분말들의 현출효과는 표면에 따라 다양하게 나타났다. 일반적으로 오징어 먹물분말은 대부분의 표면에서 좋은 현출을 보였으며 청대분말은 타일표면에서 그리고 쌀분말은 유리표면에서 최고의 현출을 보였다. 그러나 플라스틱 표면은 천연분말에 의한 지문현출이 가장 어려운 표면이었다. Field Emission Scanning Electron Microscope (SEM)를 이용한 이미지 분석에서 융선에 적절한 흡착력을 가지는 조건으로 천연분말 입자의 크기와 형태가 중요한 인자임을 확인할 수 있었다. 비록 기술적인 어려움으로 특징점의 수와 융선 피크의 면적값과의 상관관계를 볼 수는 없었으나 공평하고 객관적인 지문의 평가방법으로 기준 이미지의 사용을 통한 이미지 보정을 통하여 가능하리라고 사료된다. 저가의 저독성 천연분말은 추가적인 실험을 통하여 적절한 잠재지문 현출제로서의 가능성을 보일 것으로 사료된다.

IKONOS image mapping is being considered a possible replacement to the traditional mapping in many countries due to their ease of access to current data and their potential high resolution. Survey Department of His Majesty's Government completed traditional orthophoto mapping of all urban and semi-urban areas of the country. The 1:5000 monochrome orthophoto maps of Kathmandu Valley were completed in 2003. In 2002, as a test, production of a near natural colour Image Map at 1:5000 scale of a part of Kathmandu Valley based on IKONOS data was carried out. A conventional line map plotting of the same area at 1:5000 was also prepared. The objective of the pilot project was to assess the geometric accuracy and the information content of these maps. The details of the study and their results are underlined. The findings of the study helps to explain whether IKONOS image map can replace conventional orthophoto map at 1:5,000 for urban areas of Nepal like Kathmandu.

The purpose of this study is to construct an evaluation criteria based on the relative importance and various combinations of each evaluation index and then to appraise urban biotope in terms of nature experience and recreation. After the standard of evaluation had been developed through the review of existing literature, the relative importance of the evaluation index through expert survey was determined, and the evaluation model to assess biotope value was established. The results of this study are as follows; 1) We have constructed the seventeen evaluation criteria through literature reviews, and have provided relative importance to each evaluation index of the natural in biotope, the diversity of landscape patterns, the appearance-existence of water space, the special landscape elements, and the access based on the results of expert survey. and then we have constructed an evaluation system using the relative importance criteria. 2) To evaluate urban biotope using the evaluation system constructed, we selected 14 sites. The final evaluation results of each site is as follows; The first grade areas are the water space with semi-natural style in front of Gangchon Woobang apartments, the forest zone near Page Temple at Mt. Palgong, the edge area of Jisan and Gosan and the tendril yard against Anshim middle school. The second grade areas are Hyomyung elementary school, the farm land behind the third Anshim Jugong apartment, Ehyun put and the swampy land in front of the Kangchon and Anshim construction site. The third grade areas are Seohan and Hwasung high-rise apartments at Beummul-Dong, the Korea Manpower Agency in the Sungseo industrial zone, and the adjacent area of St. Tongil. The only fourth grade area is the commercial zone near Taegu Department Store. 3) It is highly useful to evaluate urban biotope using the evaluation criteria constructed for this research, the evaluation criteria we developed may be difficult to encompass all expert opinion and the period of space-formation is difficult to estimate urban biotopes. In the future, it is necessary to gather the basic data suitable to estimate biotope and it is necessary to develop detailed evaluation criteria applicable to estimate every biotope that has specific property.

본 연구는 새만금 농생명용지와 주변 지역의 간척 전후 생태계서비스를 평가하고 증진방안을 마련하기 위해 수행하였다. 새만금 지역의 생태계서비스 기능은 토지 유형에 따라 다르게 나타났다. 간척 전 새만금은 공급, 조절, 문화, 지지서비스 기능이 모두 높았으나 간척 후에는 공급, 조절, 지지서비스 기능이 하락했다. 따라서 새만금 농생명 용지의 생태계서비스를 증진하려면 논 습지, 저수지 등의 반(半)자연생태계가 가지는 공급, 조절, 지지서비스를 강화하는 것이 필요하다. 현재 남아 있는 산림, 도서 지역 등의 자연생태계와 광활한 농경지를 농촌관광 및 생태관광을 특화하고, 농업과 관련된 교육.연구 위주의 문화서비스 기능을 강화할 필요가 있다. 이를 위해 넓은 농경지와 농업 기반을 활용하여 농업생산, 농촌관광 등을 활성화하고 고령화가 진행되고 있는 지역에 대한 정부의 지원이 필요하다.

도시지역은 생태적 기능 쇠퇴 등 다양한 위협에 처해있다. 이러한 도시환경을 개선, 복원하기 위한 노력의 일환으로 연못형습지(Pond) 유형이 많이 조성되고 있다. 본 연구는 농촌의 반 자연형 습지 특성을 분석하여 도시지역 습지의 개선방안을 알아보았다. 수질환경 개선방안으로 인근 하천의 자연수를 유입하거나 강우의 직접유입을 제안하였다. 토양환경 중 토양산도, 유기물, 전질소 함량 등을 분석한 결과 농촌지역과 차이가 나는 원인으로는 도시지역이 인공적인 수문공급, 고사체 제거, 인공토양, 방수재 사용 등을 제시하였고 개선방안으로 설계, 시공 시 자연재료 사용, 자연형 수문상태, 가을철 식물 방치 등을 제안하였다. 조사 대상지에서 출현한 식물상은 도시지역에서 35과 69종류, 농촌지역은 53과 142종류가 확인되었고, 평균은 도시지역 4개소는 18.5과 29.3종류, 농촌지역 4개소는 26.3과 53.5종류로 큰 차이로 분석되었다. 원인으로 농촌지역이 도시지역에 비해 일년생식물에서 차이를 거론할 수 있고 개선방안으로 일년생식물이 넓게 정착 할 수 있도록 토양 및 수질 등의 기반환경을 다양하게 조성 할 것을 제안하였다. 귀화식물은 도시지역과 농촌지역에서 큰 차이는 확인되지 않았지만 도시지역의 경우 출현한 식물 중 약 1/4이 귀화식물로 구성되었다. 또한 귀화율 평균이 17.4%로, 농촌지역 귀화율 평균인 7.7% 보다 큰 차이로 높게 분석되었으므로 생활형 분석결과와 마찬가지로 일년생식물이 높게 출현 할 수 있도록 다양한 서식환경 조성을 제시하였다. 또한 도시지역 습지의 기능 향상을 위해서는 습지조성에서부터 높은 가치로 평가 될 수 있도록 배치, 재료, 서식환경 등을 고려 할 것을 제시하였다. 이상의 연구결과는 도시지역의 생물다양성 증진 및 개선을 위해 큰 역할을 담당 할 수 있는 연못형습지의 조성, 개선, 창출 등에 활용되길 기대한다.

Rice paddy fields have been recognized as an alternative habitat for avian wetland foragers, and fish-rice farms have become a new tool in improving the abundance of aquatic animals. However, the use of the habitats by avian foragers, particularly by oriental storks ($Ciconia$ $boyciana$), was not well understood. In the present study, we investigated how a fish-rice farm influenced the abundance of aquatic animals and documented the foraging behavior of the two captive bred oriental storks in a closed semi-natural paddy field. Our results showed that the fish refuge pond (water depth 40 cm) had a higher abundance of fish whereas the areas planted with rice (water depth 20 cm) had more tadpoles and some aquatic insects. The two captive bred oriental storks captured mostly fish and aquatic insects in the rice-planted area and mostly fish in the fish refuge pond. The two oriental storks had higher foraging success and spent more time for foraging in the rice-planted area than in the fish refuge pond. This result suggests that the oriental storks might prefer foraging in the area with fish, aquatic insects, and amphibians under a greater success rate presumably due to shallow water depth in the paddy fields with a fish-rice farm.
