  • 낙산복원사업 대상지의 생태계 회복을 위한 계획수립의 기초자료로 사용하기 위하여 부지 내 식생조사를 통해 자연환경을 평가하였다 현존식생도 녹지자연도 및 Hemeroby 등급을 통해 자연성을 평가한 결과 많은 면적이 산림으로서의 기능을 상실한 인공화된 지역이었다. 식생이 존재하는 지역 중 산림의 형태를 유지한 지역은 아까시나무군락을 유지하고 있었고 기타 지역은 휴경지, 논.밭 잡초군락이며 동시에 ruderal 식물군락으로 판명되었다. 성과주변에 식재한 수목은 총 67종 1,243개체였으며 그중 자생종이 27종(40.3%) 544개체(43.8%)였고 도입종과 귀화종 재배종이 각각 17%, 8.8%, 15.4%로 나타났다. 생활형 분석에서는 1,2년생 초본식물이 47%를 차지하였고 귀화율은 24.1%로 나타나 매우 불안정하고 교란된 환경인 것으로 판단되었다.

  • 영국 리즈대학과 요크대학의 연구팀은 친환경 유기농장을 유지하는 것보다 기존 농장 주변으로 자연 생태계 지역을 완충지로 두는 것이 식량 생산에 더욱 효과적이라는 연구결과를 냈다. 친환경 유기농업은 상대적으로 수확량이 적어 개간 면적이 넓어지기 때문에 결국 생태계에 악영향을 끼치게 될 것이란 분석이다.

  • This study analyzed the characteristics of emergy inputs from environmental sources that are essential in maintaining ecological processes and providing ecosystems services of the tidal flat ecosystems in Korea. Environmental sources provided a total of $4.98{\times}10^{21}sej/yr$ of emergy to the tidal flats of Korea. The emergy inputs from environmental sources were worth 1,141 billion ₩/yr. This is the value of environmental conditions that are the basis of ecosystem services provided by the tidal flat ecosystems. The emergy input per hectare to regional tidal flats decreased along the coastline from northwest to southeast, with the highest input in the Incheon-Gyeonggi area in the central western part of the Korean coast and the lowest input in the Busan area in the southeastern end. This reflects the general distribution pattern of the magnitude of tidal ranges along the Korean coast. There was no a clear-cut relationship between emergy inputs per unit area and fishery production(expressed in emergy quantity) per unit area. However, tidal flats in the west coast with higher emery inputs per unit area produced more fishery products than those in the south coast with lower emergy inputs, suggesting a possibility that the emergy inputs could be used for the rapid evaluation and comparison of the potential for ecosystem service provision by individual tidal flats.

  • This study targets the city of Paju, Gyeonggi-do, where many challenges are facing ecological assets management due to the increase in recent development. Using the survey data provided by the National Institute of Ecology in Korea, the study analysed the differences in the local residents' perception of local ecological assets. The Q methodology, which is useful for revealing differences in opinions, was applied to classify the narrative groups, which had different points of view in evaluating each asset. Next, the study compared the differences in perceptions of the vulnerability of ecological assets. As a result of the analysis, the city of Paju was divided into two main narrative groups: a 'Nature Conservation Group' and a 'Heritage Conservation Group'. The Nature Conservation Group wanted to prioritize ecologically valuable assets, such as wetlands, brackish zones, and forests. The Heritage Conservation Group preferred preserving ecological assets having a cultural contexts, such as royal tombs, graves, and the surrounding landscape. Evaluating the ecological assets, the two groups identified 23 ecological sites under threat from development among the 25 ecological sites considered. The Nature Conservation Group noted the importance of sites such as the Sannam Wetlands, Gongneungcheon, Gongneungcheon Brackish Zone, and Simhak Mountain. These were considered to be the most vulnerable ecological assets in the city. The study found differences in the perceived values for each ecological asset by residents. The results can serve as useful data for decision-making on ecological asset management in the city of Paju.

  • Many studies which assessed the function of forest are focused on usage of citizen, but studies which focused on natural-ecological function still lack. Hence, the purpose of this study is to select and apply the evaluation indicators on natural-ecological function of forest as a base research for sustainable planing and management. First, the 35 indicators were selected by the review of the internal and external 56 literature. The 12 indicators among those were reselected as natural-ecological indicator by the first survey and 7 indicators such as green area, connectivity etc. were determined through MCB analysis by the second survey. Also, the weights of 7 indicators for the functional evaluation were computed using AHP analysis by the third survey. As aresult of AHP analysis, the naturality was showed the highest indicator by 0.189, while the NDVI was evaluated the lowest indicator by 0.063. According to the result of evaluating the natural-ecological function on forest in Daegu which was selected as suitable study area, the natural-ecological functions around the Mt. Ap and Mt. Chengryong, top of Mt. Biseul had more than 85 scores, so those were assessed as an excellent area. On the other hand, the functions around the western area of Mt. Waryong and Mt. Macheon, the Mt. Daeni of Dalseong-Gun had less than 50 scores, which means that the area had to be controled by sustainable management. Therefore, we will be able to utilize the basic data for the preservation and management at urban and environmental planning through the results of this study.

  • 보전전략은 규모가 큰 지역을 설정하여야 하는 데 그 이유는 광역보전지역은 다양한 생물지리학적인 분포를 포함할 수 있기 때문이다. 이런 관점에서 본 보고서는 우리 나라의 다섯 개의 중요한 생태계에 대하여 기술하였다. 다섯 개의 생태계는 산림생태계, 담수생태계, 연안 및 해양 생태계와 도서생태계 그리고 비무장지대생태계이다. 각각의 생태계 보전전략에 대해 물리적인 측면과 생물지리적 측면에서 기술되었으며 생태계 보전방안은 생태계의 기능과 가치뿐만 아니라 자연시스템을 유지하고 복원하는 데 매우 유리하다. 생태계 보전을 위해 1) 지역주민에게 인센티브를 제공하고, 2) 연구와 교육 및 홍보의 기능을 강화하며, 3) 지역정보와 기술을 상호 교환하고, 4) 국제협력 증진을 도모, 5) 보전지역을 조성하기 위한 예산확보를 제안하였다.

  • 지역이나 국가에 따라 사람들의 색채감성에는 조금씩 차이가 있다. 색채감성에 영향을 미치는 자연환경의 요소로는 생태조건, 기후조건, 자연광조건 등으로 나뉘며, 자연광조건은 자연광의 세기와 색온도, 생태조건은 토양과 식생, 기후조건은 온도와 습도, 쾌청지수 등으로 나눌 수 있다. 이들은 인간이 지각하는 색의 색상·명도·채도와 관련을 갖고 있다. 각 지역의 풍토조건의 차이로 생기는 색채감성의 구조를 자연광의 세기에 따른 명도 변화, 대기중의 습도에 따른 채도변화, 온도차에 따른 색상변화로 나누어 파악하였다. 또한 한국과 일본을 사례로 풍토색과 도시환경색채를 통해 색채감성의 차이를 비교하여 분석하고 그 주원인을 파악하여 지역별 색채 감성을 분석하는 기틀을 마련하고자 한다.

  • This research aims to analyze the meanings that the inscription of 'jeju Volcanic Island and Lava Tubes' onto UNESCO World Natural Heritage and the promotion of Geomunoreum International Trekking Fair has given to ecotourism in Jeju. The inscription of Jeju World Natural Heritage and its extension into Geomunoreum International Trekking Fair generated important meanings in Jeju ecotourism in terms of promotion subjects and direction of the natural heritage use. First, this research holds that the local government became a crucial role on ecotourism development, along with small-sized-voluntary group tourists. Second, the research reflects the change of Jeju ecotourism characteristics from simple landscape-oriented tourism to theme tourism such as Geo-tourism. Finally it was found out that community residents were encouraged to participate in regional engagement, while I suggest for some concrete ways to induce their participation for community-based development.
