  • The purpose of this study is to evaluate the creation techniques of eco-pond, one of biotopes to promote biodiversity in urban residence area. Investigation were classified out plant, mammals, amphibia, reptiles, birds, fishes and insects. The results were summarized as follows: Around the eco-pond shows simple vegetation structurs, consisted of Pinus densoflora S et Z. and Robinia pseudoacacia under competition. In case of shrub, consisted of 4 species but plant growing appearence diversely by seasons. The evaluation of vegetation of eco-pond, there are found 4 species of aquatic plants. Inside the revetment of pond, Echinochloa crus-galli, Persicaria hydropiper, Digiaria sanguinalis, Cyperus microiria and Bidens frondosa L. are mainly distributed. Near the revetment, Trifolium repens L. and Digiaria sanguinalis are prevailed. And in its background, Erigeron canadensis, Erigeron annuus and vines are begins to make their appearances. When evaluation animals in eco-pond and contrast plot, it show simple species and numbers of mammals. It seemed to be resulted from its isolation and outside intervention by users In eco-pond, Pica pica and Streptopelia orientalis are mainly found and in contrast plot of Columba livia, which are so strong adaptation to city life environment. In case of amphibia and reptiles, none is observed in contrast plot, but in ecological pond, Rana nigromaculata and Hyla japonica are constantly observed. In case of insects, more species are found in eco-pond than contrast plot. And in eco-pond, more dragonflies are visibly increased one year after its construction. In floral zone inside of pond revetment, grasshopper and Locusta migratoria are frequently observed. In case of butterflies, they are mainly found in log fence and willow(salix) around eco-pond. In case of fishes inside of eco-pond, the species and its density are remarkable increased one year after the construction. With above evaluation results, we have identify the increase effect of biodiversity after construction of the eco-pond.

  • This study was conducted to analyze growth responses of fast growing tree species(8 clones of hybrid poplars, Salix alba, Metasequoia glyptostroboides, Liriodendron tulipifera, Acer okamotoanum, and Quercus palustris), the chemical characteristics of soil and $NO_3-N$ concentration of groundwater in a plantation applied with liquid pig manure. Concentrations of nitrogen and phosphorous in the soil treated with liquid pig manure were higher than that of the soil treated without liquid pig manure. With the exception of S. alba, DBH(Diameter at Breast Height) growth of all the fast growing tree species treated with liquid pig manure was higher than that of the species treated without liquid pig manure. In liquid pig manure treatment group, P. euramericana 'Eco28' clone showed the best performance in height and DBH growth. Concentration of nitrogen in the leaf with liquid pig manure was higher than that of the leaf treated without liquid pig manure. Based on the $NO_3-N$ concentration of groundwater analyzed during the experimental period, there was no evidence that groundwater was polluted by the liquid pig manure applied at the plantation.

  • 쓰레기 매립지에서 생장과 적응력이 우수한 수종 및 품종을 육성하기 위하여 1997년에 포플러류 4수종(10클론)과 도입종 버드나무 1수종(2클론)을 수도권매립지에 식재한 후 1997년부터 2005년까지의 생존율, 생장, 활력, 공해 및 균 해충에 의한 엽 피해, 그리고 천공충에 의한 피해를 각각 조사하였다. 전체 생존율은 1997년에 평균 90%에서 2005년에는 53%로 크게 감소하였다. 포플러 수종 중 현사시가 2005년에 66%의 생존율을 보여 가장 우수한 반면 양황철과 이태리포플러가 41%로 가장 저조한 생존율을 보였다. 현사시 3호(Clivus) 클론이 73%로 가장 높은 생존율을 보였다. 평균 수고는 이태리포플러 Eco28호가 $11.2m{\pm}2.1m$로 가장 우수하였고 그 다음으로 Clivus($11.0m{\pm}2.0m$)였다. 반면 도입종 버드나무 클론 중에서 131-27은 $7.8m{\pm}1.6m$로 가장 저조한 수고생장을 보였다. 활력, 낙엽율, 엽피해, 그리고 천공충 피해는 클론 간에 통계적 차이가 있었다. 수종별로는 현사시와 도입종 버드나무가 활력이 강하고 매립지 환경의 다양한 스트레스에 적응력이 강한 것으로 나타났으나 양황철나무는 스트레스에 아주 민감하게 반응을 하였다. 우수 클론을 한 클론만 선발하면 현사시 3호(Clivus)를, 추가하여 선발하면 버드나무 2클론(131-25, 131-27), 현사시 4호 2클론(72-9, 72-16)을 포함하여 총 5클론을 선발할 수 있었다. 이들 5클론은 수도권매립지와 비슷한 환경에 보급할 수 있을 갓으로 판단된다.

  • 본 연구는 월드컵공원 사면지구의 현존식생과 식물군집구조 조사를 통해 매립지 사면지역의 식생구조 특성 및 변화 경향을 밝혀 쓰레기매립지의 식생복원을 위한 기초자료 제공을 목적으로 수행하였다. 현존식생 변화 분석은 1999년, 2003년, 2005년, 2007년, 2008년, 2012년, 2016년, 2021년 현장조사 결과를 비교하여 주요 식생의 변화양상을 파악하였다. 식물군집구조 조사는 자연발생림 내 1999년에 설정한 고정조사구 총 6개소를 대상으로 현장조사를 실시하였다. 현존식생 변화상을 종합해보면 2010년 태풍 곤파스(Kompasu)의 영향으로 사면지구의 아까시나무는 강풍으로 인해 도복되면서 분포면적과 세력 변화가 발생하였고, 특히 건조하고 불량한 식재기반 위에서 군락을 형성하던 습지성 목본인 버드나무는 세력이 감소하게 되었다. 식물군집구조 변화상을 종합해보면 아까시나무군락은 2010년 이후 목본 종수와 개체수가 감소하다가 다시 증가하는 경향을 나타내 향후 아까시나무림이 유지될 것으로 예측되었다. 가죽나무-아까시나무-참오동나무군락은 종수 및 개체수가 아까시나무군락과 유사한 변화를 보였으며, 교목층의 참오동나무와 가죽나무는 도태된 상태로 아까시나무림으로 변화가 예측되었다. 능수버들군락은 아까시나무림으로 천이된 상태였으며, 일부 조사구에서만 교목층에 아까시나무와 함께 능수버들이 생육하고 있으나 대부분 능수버들이 쇠퇴된 상태이었다. 이들 식생군락은 월드컵공원 사면지구의 대표식생으로서 지속적인 모니터링을 통해 군락별 생태계 변화를 파악해야 하며, 생태계 복원 차원의 매립지 내 조경수식재지 조성에 있어서 중요한 기초자료로 활용할 수 있다.

  • This study was accomplished to identify and analyze vegetation structure of Mountainous Wetlands in Dan-yang and around area, and surveyed from September to November, 2006. 6 sites of total 16 potential Mountainous Wetlands by GIS based wetland forecasting system (Korea National Arboretum, 2006) were identified as wetlands throughout field survey by the indicators such as hydrology, soil and vegetation. By classification system of Korea National Arboretum (2006), types of wetlands were classified into 3 slope-types and 3 flat-types. To understand vegetation structure of wetlands, height, DBH (diameter at breast height), DI (Dominance Index), sociability and constancy were surveyed and the projection diagram and charts ware drawn. As results, Salix koreensis in woody plant layer and Persicaria thunbergiiin and Juncus effusus var. decipiens in herb layer were surveyed as broadly distributed species. The wetlands of Dan-yang around area were similar to those of Chung-ju around area, but the species of plants and hydrology conditions were different. This study is mainly focused on vegetation condition of Mountainous Wetlands. But, further studies on functional assessment for management and restoration of wetlands were necessary.

  • This paper search the difference between the village groves for enclosing and the village groves for rest in Chinan-Kun region. Both charged 72.5%(37 groves) of all(51 groves). The form of village groves for rest was various, but that of those for enclosing was linear. The average area of village groves for enclosing was 2,755.4$m^2$ and that of those for rest was 661.2$m^2$. So village groves for enclosing was 4.2 times larger than that of those for rest. In function of village groves, it was identified that function of complementing vacant part was more important than of rest in human settlement region. In the transformation of village groves, the village groves for enclosing were transformed into other productive use than those for rest. Although the worship service were performed annually in the past, that were almost disappeared in present. The forest state of village groves were almost deciduous ones. In vegetation structure, the number of upper trees of village groves for enclosing was 5 times more than that of those for rest. In average appearing rate of upper trees, the village groves for enclosing was 2 times more than that of those for rest. The most principal dominent species of both in upper trec was Zelkova serrata. The species showing highly appearing rate of upper trees were Zelkova serrata, Carpinus tschonoskii, Celtis sinensis, Qercus acutissima, Pinus densiflora, Castanea crenata, Salix glandulosa. etc.
