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.

The vascular plants in the Ohseosan and the Bongsusan, Chungnam were listed 439 taxa (9.0% of all 4,881 taxa of vascular plants); 95 families, 268 genera, 339 species, 5 subspecies, 75 varieties and 20 forms. Furthermore, the Ohseosan were listed 339 taxa and the Bongsusan were listed 306 taxa. So, Hemicryptophytes (H) were 107 taxa (24.4%), Therophytes (Th), Geophytes (G) same as were 82 taxa (18.7%) showed high proportional ratio in life form. Based on the list of rare plants, 4 taxa; Aristolochia contorta, Viola albida, Scutellaria insignis (LC) and Scrophularia koraiensis (DD) and endemic plants, 8 taxa; Aconitum pseudolaeve, Ajuga spectabilis, etc. Based on the list of specific plants, 35 taxa; Wisteria floribunda for. floribunda in class IV, 5 taxa (Scutellaria insignis, Scrophularia koraiensis, etc.) in class III, 5 taxa (Acer triflorum, Cymopterus melanotilingia, etc.) in class II, 24 taxa (Pyrus ussuriensis var. ussuriensis, Campanula punctata, etc.) in class I. Based on the list of naturalized plants, 9 families, 20 genera, 24 taxa (Persicaria orientalis, Carduus crispus, etc.) and ecosystem disturbing plants were Rumex acetocella, Ambrosia artemisiifolia. Naturalization rate was 5.5% of all 439 taxa of vascular plants and urbanization index was 7.5% of all 321 taxa of naturalized plants. In particular, for rare plants, in and ex-situ conservation of genetic resources must surely be done, by preserving present natural habitats, discovering additional natural habitats and securing seeds. Moreover, ecosystem disturbing plants require long-term monitoring and consistent management, since not only do they disturb the ecosystem in competition with Korean native species, but damage humans, too.

This study was carried out to suggest the slope revegetation technology of biological engineering using the Ligustrum obtusifolium, which is one of the pioneer plant species. Ahead of the experimental construction, we evaluated the L. obtusifolium's value of biological engineering for the slope stabilization by testing the growth rate after the cuttings were buried for 8 weeks('98. 7. ~ '98. 9.). In this test, it was found that the L. obtusifolium, one of the species deep rooted with developed underground parts, is very effective for the slope stabilization and that the rooting powder(Hormex Powder) gave the better effects on root germination. In April of 1999, the experimental construction of biological engineering technology using recycled L. obtusifolium live cuttings(applied growth-stimulating compound) and green bags was conducted at sandy cut-slope in GLEN ROSS G.C.(Yongin). The slope was tolerant of soil erosion despite of heavy rainfall in the rainy season and many plant species invading for five months('99. 4. ~ '99. 9.). The vegetation research was performed through examining the frequency of each block using the transect method. 21 kinds of plant speices appeared in total area($25.5m^2$) and the dominant species are Digitaria sanguinalis, Setaria viridis, Cyperus amuricus, Persicaria blumei, Artemisia princeps var. orientalis. With regard to life forms, therophytes were shown with a dominant distribution of 66.7% of total species and neophytes relatively with a low distribution of 19.0%. Furthermore, it can be estimated that there is no ecological stabilization of this slope with the result of the ruderal species' occupation of 71.4%. It is too early to argue about ecological mechanical advantages and disadvantages of this technology, but, from the result of this study, it is expected that the slope revegetation technology of biological engineering using L. obtusifolium can be effectively applied to sandy slope(not rock or weathered rock slope) and that the early rapid stabilization and favorable succession could be done with the improvement of soil condition.

본 연구는 가시연꽃(Euryale ferox Salisbury)을 구성종으로 하는 연못의 식재기반 조성을 위한 기초자료 획득을 목적으로, 전라북도 내의 가시연꽃 자생지 14곳에 대한 문헌 및 현장조사를 통해 자생지 식물상과 식생환경에 대한 조사분석을 통해 다음과 같은 결과를 얻었다. 1. 가시연꽃 생육지 14곳의 전체 식물상은 79과 211속 298종 2아종 30변종 6품종으로 총 336분류군이 확인되었으며, 정수성 수생식물은 17분류군, 부엽성은 가시연꽃을 포함하여 7분류군, 부유성은 5분류군 그리고 침수성 수생식물은 2분류군으로 분류되었다. 수생식물만을 대상으로 한 유사도분석 결과, 가장 유사도가 높은 정읍 한성지와 고창 석남저수지에서는 가시연꽃 이외에 부엽성식물로 연꽃과 마름이 동일하게 서식하고 있다. 따라서 가시연꽃을 주소재로 한 연못 조성시 연과 마름은 동반식물로서 생태적 지위를 보이는 것으로 파악된다. 2. 생육형별 수생식물의 출현빈도를 살펴보면, 가시연꽃 이외에 정수성식물인 뚜껑덩굴과 갈대가 각각 11회 출현하여 78.6%의 높은 빈도를 보였으며 부엽성 수생식물인 마름이 10회(71.4%), 줄이 8회(57.1%) 출현하였다. 이밖에 고마리, 겨풀, 마름, 개구리자리, 물피, 매자기, 연꽃, 어리연꽃의 순으로 출현율이 높았다. 3. IUCN 평가기준에 따른 조사대상 가시연꽃 생육지에서 발견된 희귀식물은 가시연꽃과 함께 취약종(VU)인 통발, 이외에 약관심종(LC)인 새박, 자라풀, 물질경이 등 3분류군으로 도합 5분류군이 확인되어 가시연꽃 활용 연못시 도입이 가능한 희귀식물로 분류되었다. 4. 가시연꽃 자생지의 군락유형은 대부분 가시연꽃군락이었으며 군산의 대위저수지는 마름+가시연꽃+어리연꽃군락으로 정의하였다. 자생지별 가시연꽃의 녹피율은 0.03에서 36.50으로 상당히 큰 편차를 보였으며 평균 녹피율은 9.8로 계상됨에 따라 연못 조성시 가시연꽃의 녹피율을 10% 이하의 수준으로 유지하는 것이 합리적으로 판단된다. 5. 조사대상지별 가시연꽃 자생지와 인접한 식생군락으로는 나도겨풀군락 3개소, 마름군락과 줄군락이 각각 2개소, 연꽃군락, 어리연꽃+부들군락, 마름+연꽃군락, 자라풀군락, 나도겨풀+털물참새피군락 1개소 그리고 가시연꽃+마름군락 1개소 등으로 각 저수지마다 입지조건 등에 따라 다소의 차이를 보였다. 따라서 이러한 결과는 가시연꽃을 주요 구성종으로 하는 연못의 식재설계시 동반 부엽식물의 선정 및 식피율 배분에 반영해야 할 지침으로 제안한다.
