  • The Korea Water Resources Corporation(KOWACO) proposed bidding for an alternative design for Hwabuk Multi-purpose Dam in March of 2004. The site is located in Hakseong-ri, Goro-myeon, Gunwi-gun, Gyeongsangbuk-do and has adrainage area of $87.52km^2$. The purpose of this project is to establish an environmentally friendly plan for minimizing the damage that was caused by the construction of the Hwabuk Multi-purpose Dam. The design principle of KOWACO was the restoration of the natural environment, a harmonious landscape, and the creation of a space of regional and local culture. The basic concept of this project involves an ecological-restoration axis and a functional-connection axis. The site is divided into four spaces: (1) the space of memory and symbol, (2) the space of nature and ecology, (3) the space of regional and local culture, and (4) the space of the regional economy. There are four sub-spaces in the space of memory and symbol: the track forest, the time forest, the memory room, and the sun plaza. There are three sub-spaces in the space of nature and ecology: the habitat of aquatic birds, the wind forest, and the eco-corridor. There are five themed parks in the space of regional and local culture: the culture and relic room, the wildflower garden, the ecological pond, the insect observation park, and the pyogo maze. There are three areas in the space of the regional economy: the forest pension, the waterside pension, and the community center, as Dungdungi village was reorganized to serve as a lodging complex. These themed parks, working together, can offer an effective space for nature, culture, rest, and experience.

  • Conclusion and the improvement plan according to the survey on recycling wastes in 'the program of woman and environmental education' mainly for the chairwomen of the women's association of the apartment house in City and County of Chungchongnamdo during the first half of 1998 (from March tp April) are as follows. 1. Conclusion 1) It showed that the rate of recognition for recycle has no difference by regional groups and the rate of recognition is 57.4% but they mainly know vaguely or they do not know. 2) It showed that the rate they do not know how the separated wastes are recycled is 30.4% and the scope of their knowledge is approximative.(52.6%) 3) It showed that it is the housewives who mainly do the separate garbage collection (72.7%) and 19.1% of the people have no interest in the separate discharge. 4) It showed that the rate they filter the garbage or remove water from the garbage at house is 53.1%. And 20% of the people in the urban region dump untreated wastes but 8.5% of the people in the rural region do the same, so the rate of using garbage in the rural region is higher than that in the urban region. 5) It showed that the separate state of the garbage is 29.2% for the removal of toothpick and paper and 47.4% for the removal of vinyl and stopper. 6) It showed that 66.7% of the motive for recycling waste is the education activity for environment by the women's association and SAEMAEUL association and 34.5% of that is the influence of TV and radio. 7) It showed that the rate of making compost and feed using garbage in the rural region is higher than that in the urban region and in some urban regions, the rate they sprinkle the garbage in provisional compost state on the floor garden is high. 8) It showed that the recognition rate for the material of separately collected garbage corresponding to the separate waste system of 5-6 classification is 12.5% 9) It showed that the major variable which has an effect on the recycle is the education activity for environment by the neighborhood meeting(P<0.05) and by the women's association of saemaeul activity(P<0.05)

  • This study aimed to develop a program that can be linked to gardening education activities in elementary students' curriculums and creative experience learning courses, and to apply the developed program to 6th graders in an elementary school located in Seoul. Research was conducted in a large category called biophilia, which named the instinct of human nature and nature throughout the research. The curriculum revised in 2015 was selected for the purpose of the garden education program based on the objectives and contents of the unit, and for the purpose of the class. In the process of developing and implementing the program, experience properties and elements were divided into direct and indirect experience of nature, including shapes and forms found in nature, air, water, plants, weather, animals, and natural materials. The results showed that the biophilic horticultural education program was effective in promoting students' multi senses. In the case of the experimental group, all the multi-sensory areas showed statistically significant differences, especially in the area of environmental literacy, environmental effect and emotional balance including plant cultivation knowledge. There was a relatively smaller difference in the dietary effect area than other areas because of no directional dietary program was included in the developed program. As a result, first, it is expected that the data can be utilized on site as a program or place of activity for students in upper grades. Second, it will be necessary to develop a more diverse program using other biophilic elements that were not covered in this study in order to maximize the effects of biophilic education.

  • Background: Salt marshes provide a variety of ecosystem services; however, they are vulnerable to human activity, water level fluctuations, and climate change. Analyses of the relationships between plant communities and environmental conditions in salt marshes are expected to provide useful information for the prediction of changes during climate change. In this study, relationships between the current vegetation structure and environmental factors were evaluated in the tidal flat at the southern tip of Ganghwa, Korea, where salt marshes are well-developed. Results: The vegetation structure in Ganghwa salt marshes was divided into three groups by cluster analysis: group A, dominated by Phragmites communis; group B, dominated by Suaeda japonica; and group C, dominated by other taxa. As determined by PERMANOVA, the groups showed significant differences with respect to altitude, soil moisture, soil organic matter, salinity, sand, clay, and silt ratios. A canonical correspondence analysis based on the percent cover of each species in the quadrats showed that the proportion of sand increased as the altitude increased and S. japonica appeared in soil with a relatively high silt proportion, while P. communis was distributed in soil with low salinity. Conclusions: The distributions of three halophyte groups differed depending on the altitude, soil moisture, salinity, and soil organic matter, sand, silt, and clay contents. Pioneer species, such as S. japonica, appeared in soil with a relatively high silt content. The P. communis community survived under a wider range of soil textures than previously reported in the literature; the species was distributed in soils with relatively low salinity, with a range expansion toward the sea in areas with freshwater influx. The observed spatial distribution patterns may provide a basis for conservation under declining salt marshes.

  • Comparative studies of the effects of rates and frequency of application of dairy slurry on herbage yield and stand persistence of alfalfa and various forage grasses have not previously been conducted. The results being reported here are part of a larger study having a primary objective of comparing the effectiveness of alfalfa (Medicago sativa L.), various grasses and alfalfa-grass mixtures for utilizing nutrients from applied dairy slurry. The objectives of this part of the study were to evaluate the effects of various rates and frequencies of application of slurry on herbage yield and stand persistence of orchardgrass (Dactylis glomerata L.), reed canarygrass (Phalaris arundinacea L.), and alfalfa-orchanrdgreass and alfalfa-reed canarygrass mixtures managed as a 4-cutting management system. A randomized complete block design with treatments in a split plot arrangement with four replicates was used. The main plots consisted of 9 fertility treatments: 7 slurry rate and time of application treatments, one inorganic fertilizer treatment, and an unfertilized control. The sub-plots consisted of the two grasses and two alfalfa-grass mixture mentioned above. Slurry was composed from stored solids scraped from the alleyways of a free-stall housing barn and water added to form a slurry having about 8% solids. Manure was pumped from a liquid spreader tank into 10.4 L garden water cans for manual application to the plots. Herbage yields within species were generally unaffected by various rates of application in the first production year. Herbage yields of grasses and alfalfa-grass mixtures the second year were generally not affected by frequency of application for the same rate of slurry applied. Slurry application resulted in greater herbage yield increases in grasses than alfalfa-grass mixtures in the 4-cutting management system. In general, herbage dry matter yields of grasses from the dairy slurry treatments equaled or exceeded yields from the inorganic fertilizer treatment. Stand ratings of grasses and alfalfa-grass mixtures were not changed by manure application rates. In this study, the highest rate of slurry ($967kg\;total\;N\;ha^{-1}$ in 1995 plus $2,014kg\;N\;ha^{-1}$ in 1996) was not detrimental to herbage yields or stand persistence of any of the species. It was concluded that applying dairy slurry to these cool-season grasses and alfalfa-grass mixtures managed in a 4-cutting system is an acceptable practice from the standpoint of herbage yield and satnd persistence and by doing so the utilization of inorganic fertilizers can be reduced.

  • 본 연구는 제천시에 위치한 솔방죽 습지생태공원의 조성 전과 후의 동물상을 비교하였다. 그 결과, 생태공원 조성에 따른 동물상의 변화는 야생성이 강한 종들이 감소하고, 일반종의 비율이 높아지는 것으로 나타났다. 또한 포유류, 양서 파충류와 같이 이동에 제약이 있는 종들은 생태공원 조성으로 늘어난 탐방객들에 의해서 점차 감소하고 있다. 그리고 어류는 공원 조성과정에서 저수지 물을 방류하고 작업하여 집단 폐사하는 사례가 있어 이에 대한 보완 작업이 필요하다. 곤충은 공원 조성 후에 조성된 화단의 꽃에서 꿀을 먹는 곤충과 습지 식물의 생육을 위하여 안정된 수계를 유지하고 있어, 이곳에서 서식하는 수서 곤충은 늘어난 것으로 나타났다. 이번 조사 결과, 주거지역과 인접한 농업용 저수지는 크기가 작은 경우가 많아 생태공원 조성시 이곳에서 생활하는 야생동물들에 대한 서식 공간 확보가 필요한 것으로 보인다. 또한 야생동물 서식처를 위하여 방문객들의 탐방로와 시설물 위치를 조정하여 저수지 일부 지역이 자연 상태로 유지할 수 있도록 하는 것이 고려되어야 한다.

  • 정수식물인 줄(Zizania latifolia)의 생장에 따른 저토로부터의 무기영양소 흡수와 저토의 산화환원전위(Eh) 및 pH와 같은 물리, 화학적 특성과 $NH_4^+$$NO_3^-$의 질소형 그리고 유동성 인$(PO_4^{3-})$, 착화합물 인, 인회석 인 및 유기 인의 변화를 화분 재배실험을 통하여 조사하였다. 화분재배 실험에서 저토의 Eh는 식재 후에 식물구의 환원층이 무식물구의 것보다 높았다. 환원층의 $NH_4^+-N$ 함량은 식물구가 무식물구보다 적었고, $NO_3^--N$ 함량은 그것과 반대의 양상으로 나타났다. 형태별 인의 비율은 식재 전에 유기 인이 높았고, 식재 후에 착화합물 인이 높음으로써, 전자가 분해되어 후자로 변형됨이 확인되었다. 상층수와 침출수의 $NH_4^+-N$$PO_4^{3-}-P$ 농도는 무식물구보다 식물구에서 낮았다. 침출수의 $NO_3^--N$ 농도는 무식물구보다 식물구에서 높았고, 이는 뿌리로부터의 산소공급이 저토를 산화시켰기 때문인 것으로 판단되었다.

  • The purpose of this study is to provide the conservation management direction about cultural landscape of the traditional villages in the area of Huizhou through the importance-performance analysis. The results of the survey on the importance - performance of 261 people who had many visits to various cultural landscapes of Huizhou villages such as Hongchun, Sidichun etc. are as follows. It was appeared that the item of 'good air' is the highest level of importance and satisfaction and is best condition. The item of 'historical conservation' is the high level of importance, but the level of satisfaction is low, so continuous improvement is necessary. The item of 'Old garden conservation' has high satisfaction but low importance, so it needs to improve its importance through subsequent improvement. The item of 'Keeping of old cemetary and old tower' has low importance and satisfaction but it is above average, so continuous maintenance is needed. The items of 'Preservation of stone gate' and 'Preservation of famous man's birth house' all have slightly higher satisfaction and lower importance. Both items are highly satisfied with their importance, so they should avoid excessive efforts and maintain the present status. Satisfaction with the item of 'water environment and water quality' was the lowest, and the problem of the present condition is the most serious, and a major improvement is needed. The importance and satisfaction of 'Commercial development of old villages' was the lowest among all items. This item is causing serious problems and should provide an overall improvement way to drastically improve the importance and satisfaction. Concentration is necessary to improve the environment of the whole villages, to protect the ecological plants and animals in old villages, to transfer and improve the culture of old villages, to maintain sustainability of the villages, and to protect old temple and old rock in old villages. As the level of satisfaction with sustainability is the lowest in the part of 'Concentrate here', there is a great concern about sustainability. Therefore, it is necessary to focus on sustainability and concentrate on sustainable development.

  • 국내의 경우 LID 기술은 2009년 이후에 적용하기 시작하여 환경부, 국토부, LH공사 등의 사업지구와 공공기관, 상업용지, 주택, 공원, 학교 등에서 빗물 관리를 위해 LID 시설을 설치하고 운영 중이다. 그러나 국내의 사례를 살펴보면 국외에 비해 적용사례나 운영 기간 등이 충분하지 못하여 적절한 설계기준과 운영 및 유지관리에 대한 방안 제시가 미흡한 실정이다. 특히, LID 기술을 활용하여 시공되는 LID 시설은 고유의 물순환 기능으로 발현하는 물질순환과 에너지 흐름으로 수문학적 및 환경적 효과가 발현되기에 LID 시설 내부의 지속적인 환경 유지가 필요하다. LID 시설은 물순환 목표량에 계획된 처리용량으로 설계가 되며 적절한 유지관리와 식생 및 토양의 상태를 주기적으로 파악하여 최초에 설치된 상태를 최대한 유지해야 그 효율을 얻을 수 있다. 즉, LID 시설은 물순환 구축을 통한 물의 저류와 침투능을 증대시키면서 수질오염저감, 홍수저감, 수자원확보, 온도저감 등의 효과를 기대하는 시설이기에 LID 시설에 조성되는 토양은 매우 중요한 설계 요소이다. 정확한 LID 시설의 기능 유지와 관리를 위해서는 토양오염, 제설제 영향, 식생 기준 등의 다양한 정량적 데이터를 통해 시설의 현재 상태와 교체 및 유지관리의 주기를 정확하게 알아야 한다. 본 연구에서는 2009년부터-2020년까지 국내에 설치된 LID 시설의 현황을 조사하고, 그 중 식생형 시설인 빗물화단, 식생수로, 식생체류지 등을 대상으로 하여 토양층에서 토양시료를 채취한 후 지난 10년 간 적용된 LID 시설의 지속성과 현재 상태를 통해 토양의 변화를 분석하고자 수행되었다. 토성, 유기물, 경도, 함수량, pH, 전기전도도, 염분 등의 분석을 통해서 시공후 5년~7년 이상된 일부 식생형 LID 시설에서 조경설계기준 하급치에 해당하는 결과를 나타냈다. 하급치 이하의 시설은 토양의 투수율 저하와 식생 생육에 문제가 될 수 있는 상태로 유지관리가 필요한 시점으로 인식할 수 있다. 이에 따른 토양치환과 교체를 통해 LID 시설을 관리해야 함을 알 수 있었다.
