한국 전통 연지의 시원으로 평가되는 궁남지는 "삼국사기"에 나타난 무왕의 연지 축조 기록, 사비왕궁으로 추정되는 관북리 유적 및 화지산 이궁지 남쪽에 위치한 지리적 정황에 의해 궁남지로 비정되는 한편 사적으로 지정 복원되었다. 본 연구는 궁남지의 복원정비 과정에 나타난 진정성 왜곡과 전통의 발명에 초점을 맞추어 고찰되었으며, 연구의 요약된 결론은 다음과 같다. 1. 마래방죽[마천지]으로 불려왔던 궁남지는 일제 강점기 때만 해도 3만여 평의 광대한 자연 저습지의 상태로 존재했다. 궁남지 복원에 주도적인 역할을 했던 홍사준은 1940년대만 해도 마래방죽에 백제시대 궁남지 유적으로 추정되는 섬과 석축시설이 남아있었고 그 위에 전각 및 정원을 조성한 흔적이 발견되었다고 전했다. 또한 화지산 이궁터의 조사 후 서동설화와 연관시켜 마래방죽을 궁남지와 동일시하는 의견을 피력하였는데, 이는 궁남지 복원정비의 이론적 근거로 작용하였다. 특히 홍사준이 제시한 스케치 도면 및 부여도엽에서 마래방죽의 형태와 규모를 엿볼 수 있었는데, 이러한 방죽의 형태는 일제 강점기에 촬영된 사진 속 상황과 근사한 것으로 판단된다. 2. 궁남지의 축소정비는 1960년대 추진된 경지정리사업에 의해 농경지로 불하되고 남은 잔여의 면적이 수습된 결과였다. 1965~67년에 있었던 최초 복원공사 이래 수차례 시행된 궁남지 정비를 통해 드러난 문제는 고고학적 사실에 근거하지 않은 채 후대의 시각으로 추정복원 되면서 경복궁 향원지의 구성을 그대로 복제한 데 기인한다. 구체적으로, 연못 안에 섬과 정자를 놓고 교량으로 섬과 육지를 연결시키는 구성은 궁남지가 경복궁 향원정을 모델로 만들어졌음을 방증해 준다. 하지만 교량설계에 참조된 취향교 조차도 조선시대의 형식으로 보기 어려운바 당시의 잘못된 복원설계의 동기와 발상이 궁남지의 가치를 크게 저하시켰다고 판단된다. 이처럼 전통조경의 소재로서 이미 널리 알려진 디자인 전범을 그대로 모방한 것은 경복궁이 갖는 미적 표상과 기호를 지향한 것으로서, 궁남지가 그와 유사한 장소 권위를 획득하도록 의도된 것이었다. 3. 궁남지는 애초부터 진정성이 결여된 채 정비된 사적이었기 때문에 정비 과정에서 경관의 왜곡과 전통성의 남용을 통해 유적의 역사적 맥락이 과감히 표방되어 갔다. 이러한 역사 재료의 무비판적인 활용과 왜곡을 불사한 정비방식은 1960~70년대 박정희 체제에 의해 주도된 민족주의 문화정책과 맞닿아 있다. '만들어진 전통담론'의 맥락에서, 박정희 시기의 문화정책은 국민의 기억에서 이상화된 과거를 취사선택하여 그것을 가시적으로 부각시키는 방향으로 전개되었다. 그 결과, 이전의 유적을 보수하는 수준을 넘어서서 화려하고 웅장한 모습이 부각된 사적지가 전국 곳곳에 생겨나게 되었는데, 궁남지가 초기에 순수한 보존의식으로 축소되어 정비되었음에도 불구하고 점차 본래 공간과는 상관없는 새로운 건조물들이 들어서고 기형적으로 확장 정비되어 갔던 사실은 그러한 국가주도 문화정책의 영향이 컸다고 판단된다.

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.

Treatment efficiency was examined of a pond-wetland system constructed for water quality conservation of Koheung Estuarine Lake over one year after its establishment in July 2000. The system is composed of primary and secondary ponds in series and six wetland cells in parallel. Cattails (Typha angustiflora) were planted in three wetland cells and common reeds (Phragmites australis) in three other cells. Water pumped from Sinyang Stream flowing into the Lake was funneled into primary pond whose effluent was discharged into secondary pond by gravity flow. Effluent from secondary pond was distributed into each wetland cell. SS, $BOD_5$, T-N, and T-P concentrations in influent to primary pond, and effluent from primary pond, secondary pond, and three wetland cells planted with cattails were analyzed for about one year from August 2000 to August 2001. The removal rates at primary pond for SS, $BOD_5$, T-N and T-P were 29%, 30%, 15%, and 36%, respectively. The abatement rates at secondary pond for SS, $BOD_5$, T-N and T-P were 38%, 40%, 30%, and 47%, respectively. The reduction rates measured at three cattail-planted wetland cells for SS, $BOD_5$, T-N and T-P were 54%, 57%, 60%, and 68%, respectively. Considering early stage of the pond-wetland system and inclusion of winter during the research period, its treatment efficiency was rather good. Cattails had not yet grown to dense stands due to initial establishment period, which resulted in slightly lower treatment efficiencies of wetland cells for these pollutants, compared with those of ponds.

The purpose of this study is to develop a method to spread out the ecological ponds in urban areas more effectively. It is urgent to supply the ecological ponds in more broad scope to ensure the water space in urban areas which has been dried out. It is necessary to formulate a plan for improving the amenity in the cities through creation a biotop in swampy land by building rainfall ponds. Thus, a model of the ecological pond in this study has been developed by reviewing the related researches which provide the theoretical basis and by considering the characteristics of nature for a naturally approached pond. This study has produced a ecological pond model in order to introduce and spread out damp biotop. Ecological aspects have been mainly considered in designing and building the pond model. This model consists of areas for emerged plants and bog plants and has its advantage in providing animals and insects with habitats and shelters. In addition, the model includes areas for emerged plants, which are very effective in purification of the rainfall from the rooftop. After the construction of the pond, the plants were planted according to the plan, and the infiltration trench was installed beside the pond to drain out the overflow of the pond. The result of this research has shown the possibility of supplying the ecological pond in small parks and in schools of the city in an easy way. Through the application of this pond system, the water cycle and the ecosystem in urban areas will be improved.

Treatment level and pond reactions of a pond system were examined from May to October 2002. The system was constructed in July 2000 for purifying water of Sinyang stream that flows into Koheung Estuarine Lake located in the southern part of the Korean Peninsula. The system was composed of a primary and a secondary pond in series and established on the rice field near the lake. Water pumped from the stream was funneled into the primary pond, whose effluent was discharged into the secondary pond by gravity flow. Effluent from the secondary pond was funneled into wetlands. About 130 $m^3$/day of water was pumped into the primary pond and detention time of the primary and secondary pond was about 2 days. DO from the surface to the 1.0 m depth of the primary and secondary pond was in the rage of 5.2 to 11.0 mg/L and 4.3 to 0.7 mg/L, respectively. DO at the bottom layer of the primary pond was 0 mg/L and that of the secondary pond ranged 3.0~4.7 mg/L. The primary pond functioned as a facultative pond and the secondary as an aerobic one. The temperature difference between the surface and bottom layers of the ponds in August was about $2.5^{\circ}C$ and that in May and October was about $1.0^{\circ}C$. Thermocline was observed in the primary pond during the high ambient temperature of August. The sludge depth of the primary pond in May, August, and October was 2.4, 1.9, and 2.2 cm, respectively. That of the secondary pond was 1.2, 1.0, and 1.1 cm, respectively. SS, $BOD_5$, T-N, and T-P concentrations in influent averaged 16.64, 6.71, 6.21, and 0.23 mg/L and those in effluent from the primary pond averaged 11.48, 4.97, 4.81, and 0.17 mg/L, respectively. The removal rates of the primary pond for SS, $BOD_5$, T-N and T-P were 31%, 26%, 22%, and 24%, respectively. Average concentrations of SS, $BOD_5$, T-N, and T-P in effluent from the secondary pond were 9.81, 4.07, 4.03, and 0.14 mg/L, respectively and the abatement rates of the secondary pond for SS, $BOD_5$, T-N and T-P were 20%, 12%, 13%, and 15%, respectively. SS, $BOD_5$, T-N and T-P concentrations in effluent from the primary pond were significantly low(p=0.001) when compared with those from the secondary one.

A Sustainable Structured wetland Biotop (SSB) system was planned, designed, and finally constructed, and maintained in the An-teo Reservoir ecological park, which is the habitat of the endangered Gold-spotted Pond Frog. The system purifies polluted water of An-teo Reservoir which flows from up to bottom within the system. Water was sampled once a month at the inlet and at the outlet from December, 2009 to August, 2010. BOD5, SS, T-N and T-P were analyzed. Average influent and effluent BOD5 concentration was 2.9 and 1.0 mg/L, respectively, and BOD5 removal was 67%. SS concentration of influent and effluent averaged 18.1 mg/L and 2.5 mg/L, respectively, and SS abatement amounted to 86%. Average influent and effluent T-N concentration was 0.426 mg/L and 0.147 mg/L, respectively, and T-N retention was 66%. T-P concentration of influent and effluent averaged 0.071 mg/L and 0.022 mg/L, respectively, and T-P removal amounted to 68%. Plant and frog species of the system were monitored during the period. Amphibia and reptiles provided 7 species and 4 families including the Endangered Gold-Spotted Pond Frog (Rana chosenica ) which also lives in the system. Twenty-six plant species were naturally introduced into the system, however, they didn't make up a significant portion of the plant populations compared with the planted species. The endangered plants, Bladderwort (Utricularia vulgaris var. japonica ) and Euryale ferox were observed in An-teo Reservoir as well as in the system.

본 연구는 종묘(宗廟)의 지당(池塘)을 대상으로 조선시대부터 근현대기까지 진행된 변천과정의 규명에 목적을 두고 있다. 이에 따른 연구결과는 다음과 같이 요약될 수 있다. 종묘 지당에 관한 최초의 기록은 "세종실록"에서 확인된다. 세종 25년(1443)에 조성 중이던 지당은 지금의 상지(上池)를 가리키며, "국조오례의" "종묘전도"에 따르면 중도(中島)가 없는 형태의 방지(方池)였다. 숙종대의 중지(中池)에는 쌍도(雙島)가 조성되어 있었고, 중도(中島) 내에는 단풍나무, 박달나무 등을 비롯한 여러 수목이 식재되어 있었다. 또한 중지 내에는 무성한 연꽃도 자라고 있었다. 특히 쌍도 형식이었던 중지의 중도는 이후 단도(單島) 형식으로 변화하였는데, 영조(英祖) 연간에 이루어진 지당의 확장공사와 관련되었을 가능성이 높다. 근현대기에 이르러 이원적(二元的) 배치의 하지(下池)가 조성되면서 종묘의 지당은 본격적인 변형국면에 접어들었다. 근대기의 항공사진에 의하면 하지는 적어도 1947년 이전에 조성되었는데, 1980년대 중반에 이르러 이원적 배치의 하지 가운데 우측 하지가 매립되면서 일원화된 형태의 하지가 나타나게 되었다. 한편 "종묘배치도"와 국가기록원 소장 사진첩에 의하면 상지와 중지의 호안(護岸)은 본래 토축(土築)으로 조성되었지만 이후의 어느 시점에 석축(石築)으로 개축되어 현재에 이르고 있다.
