  • This study monitored the changes before and after restoration of ecological stream focusing on the places which are applied Sustainable Structured wetland Biotop (SSB) system and ecological Fish-way for restoration of Maeno stream. A total of 11 species and 191 individuals of fishes were founded out which were not verified inhabitation before restoration at SSB wetlands. Especially, it was could identified that micro habitat and healthy Fish-way was created because the restored target species, Microphysogobio yaluensis and Iksookimia koreensis were identified that habitation was monitored in SSB wetland. Amphibian have been restored to a number of Rana nigromaculata found in and around wetlands at the time of the third survey, which is highly active after restoration. Specified endangered species class 1 and natural monuments designated by the Ministry of Environment, Lutra lutra lutra, as a Mammalian, uses the wetlands and ecological Fish-way as habitat areas, and the his habitat is restored. In the case of Flora, vascular plants emerging in the survey area were increased to 7 and 13 species before restoration and 15 and 19 species directly after restoration, and 22 species and 33 species after restoration. Vegetation after restoration was found to be a basic producer of various ecosystems and a plant community that contributes to the purification of water quality such as Phragmites japonica communities. As the result of water quality monitoring, the average of treatment efficiencies were BOD 64.3%, T-N 47.2%, T-P 80.7%. Successful treatment of the nonpoint pullution source, which is a limiting factor to disturb the ecosystem, creatively restored the target species in the water quality class I, II.

  • This study surveyed an ecosystem conservation area that is wetland area to establish ecological restoration and preservation plan. Monitoring standard have been set up item, method, period, number of times etc. Result that examine according to monitoring standard, Plant field investigated Flora, actual vegetation. Flora is 132 taxa(39 family 116 species 19 variety 1 forma) appeared and wild species were 85 species, and introduced species were 47 species. Grasped monthly(April∼September) actual vegetation, swampy plant community influence were increase and influence of Persicaria thunbergii was big situation specially. Frequency appearance of naturalized plant is much on field. Animal field investigated Birds, Herpetofauna, Insecta. Birds were appeared 34 species 378 individual and Herpetofauna were appeared 4 species 5 individual and insecta investigated 11 order 52 family 153 species. Inorganic environmental field investigated groundwater level, quality of water, soil quality. Groundwater level is high by 0.0∼89.0cm, $Ca^{++}$ content is some high by 2.18∼13.73cmol/kg in soil. Also we suggested basis direction and each space details plan on monitoring as follow : wetland ecosystem restoration plan, eruption area restoration plan, forest ecosystem restoration plan.n.

  • 본 연구에서는 하천구조물에서 자연과의 조화를 고려하여 생물과 공생을 목표로 한 다양한 접목시도를 통해서 Mattress/Filter시스템을 이용한 하천 본래의 기능인 환경생태기능을 회복시킬 수 있는 방안을 강구하고, 생태기능이 저하된 하천의 생태계 질을 향상시켜 건전한 하천생태계를 복원시키는 Mattress/Filter의 수질개선시스템의 개발을 시도하였다. 수변생태계 복원을 고려한 Mattress 시스템의 설계는 주위의 경관과 조화를 배려하여 도입을 결정하고, 법면구배 변화점의 모서리가 완만하도록 Mattress의 배치 및 크기를 결정하여 식생에 의한 피복이 가능토록 설계해야 한다. 이 치수 기능을 유지하면서 생태계를 보전하기 위한 대안으로 생태복원구조물인 친환경 Mattress/Filter 의한 수질개선시스템을 개발하여 기존하천에 초본식물들이 식생됨으로써 수질이 개선되어 하천 본래의 생태계를 유지할 수 있는 늪지 조성, 하천의 친수성 확보, 수변식물에 의한 동식물의 서식처 제공 및 수변경관이 보전된 식생 수변공간에 조성에 필요한 기법을 제시하였다.

  • Ecological restoration is an ecological technology that diagnoses problematic ecological spaces and restores the damaged ecosystem to a healthy appearance similar to its original appearance based on reference information obtained by analyzing intact nature. To achieve successful restoration, the project must be carried out in respect of a series of procedures. However, in Korea, restoration projects are usually actively promoted regardless of diagnostic evaluation, which wastes cost and energy, and the effect is not significant. As the reference information is not utilized, ecological restoration to return the damaged nature makes features different greatly from the appearance of nature, causing another damage. As the restoration effect is not evaluated, it is impossible to determine whether it is successful or not, and as a result, even if the project continues, there is no development and no effect. However, advanced societies have not only made academic progress by respecting these procedures but also have great economic effects along with the improvement of environmental conditions as ecological restoration has become an industry. Therefore, the international society recognizes ecological restoration as an important means of solving environmental problems at the global level, including climate change, and international organizations are actively promoting projects to treat the injured planet. However, most of the restoration projects promoted in Korea were evaluated below the level as a result of the evaluation of the effect. Nevertheless, those who have led low-quality projects are blocking plans to establish ecological restoration as a new industry that can contribute significantly to improving these levels, and thus the problem is expected to worsen. To solve this problem, it is necessary to filter out defective businesses by introducing a strict and correct project evaluation system by dividing it into before and after. Furthermore, it is necessary to establish ecological restoration as an industry and leave the process in the principles of the market.

  • This study aims to identify and reduce the gaps of understandings and thoughts of river restoration between river engineers and ecologists by logically re-examining the definition and value of river restoration. For this purpose, function, and goods and services of river ecosystem are analyzed based on the study of those by de Groot et al. (2002). From the result of this analysis, definitions and strategies of presently-known river restoration and its similar activities are re-examined. Next, presently-known river restoration models, ERM (Ecological restoration model), ARM (Amenity restoration model) and semi-ERM (semi-Ecological restoration model), are reinforced in their frameworks. This study is expected to narrow the gap, between the professionals of different fields, of their understandings and thoughts of river restoration.

  • 최근의 하천복원 사업은 제외지 중심의 하천복원에서 벗어나 제내지의 격리 차단된 구하도까지 복원하고자 하는 노력이 시도되고 있다. 그러나 하천복원에 따른 수리적 및 생태적 연결성 향상이 적절히 수행되는지에 대한 정량적 평가 수단이 부족한 상태다. 본 연구에서는 구하도 복원에 따른 생태적 연결성 평가수단으로서 복원전 후 수리해석 결과를 이용하여 대상어종의 서식처적합도지수(HSI)와 식생의 공간분포를 분석 또는 예측할 수 있는 모형을 개발하였다. 공간분포된 수리특성을 위해서는 2 3차원의 모형이 필요하지만 복잡한 계산과정, 고도의 기술 및 많은 시간과 비용이 필요하다는 점에서 접근이 용이하지 않다. 이에 1차원 홍수추적모형의 결과를 이용하여 1차원 수리특성을 2차원으로 확장시키는 수치모형도 함께 개발하였다. 다만 개발된 각 모형의 단계별 실행 결과는 개별적인 요소의 평가로서 그 의미가 작으므로 하천복원의 종합적 평가를 위한 수리-물리서식처-식생의 통합적 모의가 필요하다 개발된 모형의 사용성 증대 및 생태적 연결성 평가 통합모형으로의 발전을 위해 개발된 모형을 하나의 연동시스템으로 구축하고자 하며, 연동 시스템을 이용하여 수리적 및 생태적 연결성을 신속하고 간단하게 해석할 수 있다.

  • 본 연구는 수도권 지역의 아까시나무림을 중심으로 식물군집의 식생구조적 특성을 분석함으로써 향후, 도시녹지의 자연성 복원을 위한 기초 자료로 제시하고자 하였다. 조사지역은 서울도심지역으로 중구 남산과 서대문구 안산, 서울외곽지역으로 은평구 봉산과 부천시, 성주산, 비도시지역으로 경기도 천마산을 선정하였다. 주요 연구분야는 생태적 특성과 복원모델로 구분하였가. 생태적 특성평가는 천이단계, 자연성 및 다층적 식생구조와 종다양성을 실시하였으며, 복원모델은 적정수종, 개체수, 흉고단면적, 수목간 최단거리를 선정하였다. 조사결과, 복원모델은 비도시지역 중 자연성이 높으며 다층구조를 이루고 있는 자생식물군집을 선정하였으며 적정식물은 교목성장 3종, 아교목성정 7종, 관목성장 16종, 주연부 수종 4종 초본식물 27종이 적절한 것으로 판단되었다. 향후, 아끼시나무림읜 자연성 복원을 위해서 자연림인 참나무류로의 천이를 유도할 수 있도록 자생종 중심의 생태적 복원방안의 모색이 이루어져할 것이다.
