  • 도시림의 경관생태학적 관리를 위한 기초정보를 수집하기 위하여 대구광역시 시가지에 분포하는 고립된 잔존 임지 3개 공원을 대상으로 비오톱 유형을 구분하고, 그 기능적 등급과 식생경관의 구성적 특성을 평가하였다. 비오톱 유형은 소분류군을 기준으로 대개 15~20개 유형으로 나타났으며, 공원 면적이 클수록 비오톱 유형의 다양성과 평균 면적도 크게 나타남을 알 수 있었다. 비오톱 등급은 생물이 살아가기에 부적당한 낮음(1~3등급)이 전체의 72.7%로 대부분을 차지하고 있었으며, 높음(7~9등급)은 전혀 나타나지 않았다. 기능적 가치등급에 있어서는 중간(등급 3)과 그 이하(등급 4~5)가 대부분으로 나타났으며 비오톱 공간 면적이 클수록 등급도 다소 높아지고, 등급이 높을수록 상대적으로 저온역을 나타내고 있음을 알 수 있었다. 식생경관의 구성적 특성은 아까시나무, 상수리나무가 공원에 관계없이 우점경관요소형으로 나타나 아주 단순하였으며, 그 평균 면적도 대개 1 ha미만의 아주 작은 공간규모를 나타내어 산림생태계 구성요소로서의 기능적 역할의 연속성에 많은 문제가 있는 것으로 판단되었다. 결론적으로 도시내 잔존 임지에 있어서 비오톱 유형의 다양성과 기능적 가치를 증대시키기 위해서는 각 유형별 생태적 최소면적을 확보를 위한 유사 비오톱 유형의 공간적 통합을 위한 경관생태시업이 필요한 것으로 판단되었다.

  • This study suggests the methods of the assessment and creation of biotopes in small and medium sized cities, in Korea. For this purpose, Chonju city was selected to classify and asses the biotope types. Moreover, relevant legislations to conserve and enhance urban biotopes were examined. The results of this study are as follows: 1) There were two approaches to asses the potential of urban biotopes in medium-sized cities. One was the urban scale evaluation for urban green spaces and the other was the biotope scale evaluation for the classification and evaluation of biotopes. 2) The urban scale evaluation was developed through overlaping analysis of landuse and vegetation factors. This study also included the conception of watershed. In this conception, three watersheds in Chonju city were characterized. According to these characteristics, individual programs for conservation and enhancement of urban green space were suggested. 3) For the biotope scale evaluation, Selected site was inclusively mapped and field investigation actually was carried. There were total 9 types of bitopes. Especially landuse was appeared in various evaluation items were vegetation structure, area of green space, condition of vegetation and vegetation profile. Mt, Gonji and Dukjin park, Chonbuk national University and fields were evaluated highly I the potential. 4) The biotope programs were based on the results of assessment and physical characteristics of biotopes. The uniform and simple levels on vegetation must be modified with various levels of vegetation structure and vernacular plants. And the physical characteristics like Points, Corridors and Patches can be organized by the conception of biotope networking theory. 5) The proper legislative environment was the clue elements for the biotope programs. Until now, only five types of parks and two types of green space are defined and the minimum size of green space has been proposed by the law. So, it is necessary to enlarge the conception of green space in legislation and improve the quality of green space by amending the related regulations. This study has limitation because it was selected only in Chonju. Through the continuous studies, we need to apply this other small and medium sized cities, South Korea. Also the data collection and management of theme maps such as actual vegetation, landuse and a soil must be done preliminary.

  • The purpose of this study was to analyze biotope types of urban land-use patterns. Forest areas were considered according to vegetation type and potential for succession. Urban ecosystem structure was analyzed according to land use, land coverage, vegetation structure (actual vegetation, diameter at breast height, layer structure, and revetment). As a results of the classification, the biotopes were divided into 71 types according to the urban ecosystem structure. In the case of the Hanam province, the biotopes were divided into 51 types: 26 forest types; 5 swampy and grass land types; 3 farm land types; 3 types of planted land, and 8 types of urbanization.

  • Coastal sand dune systems are particularly fragile and threaten the environment. However, these systems provide fundamental ecosystem services to the nearby urban areas, acting, for example, as protective buffers against erosion. In this paper, we attempt to classify the biotope types of coastal sand dune ecosystems and select an index for the assessment of the conservation value. The types of biotopes are categorized based on the vegetation map; floras are examined in order to research the effects of hinterlands on coastal sand dunes. In addition, a naturalization rate and an urbanization index for each biotope type in hinterlands are analyzed. In the ecosystem of coastal sand dunes, the urbanization index and naturalization rate shows a higher value in sand dunes with areas of road, residential, and idle land in farm villages, rice fields, and fields. On the contrary, a lower value in the urbanization index and naturalization rate is present when typical biotope types, such as sand dune vegetation and natural Pinus thunbergii forests, are widely distributed. Based on these results, urbanization index and naturalization rate should be used as critical indices for the assessment of the ecosystem of costal sand dunes.

  • This research has a meaning to provide basic data for eco-friendly way of district unit plans and ecological landscape planning by evaluation of biotope preservation value at the level of district unit and designating land development of the site, the whole area of Sinseo-dong (Dong-gu, Daegu metropolitan city) for research site. The summary of analysis result is as follows. As a result of classification of biotope types on the research site, it is divided into 11 biotope groups such as a residential biotope group and 51 specific biotope types which is subordinate to the groups. As a result of the first value assessment on classified biotope types, there are 16 types of natural rivers which is full of vegetation as a I class. Also it is analysed as 9 types of IIclass, 14 of IIIclass, 8 of IVclass, and 4 of Vclass. In particular, in light of a wildlife habitat, EB, in case of broad-leaved tree of mixed forest assessed as a II class, was classified into Iclass which is one-step upgraded as a final class with the analysis as there is a structural characteristic (more than 71% of low density, 50 years of age-class). As a result of second assessment, it is analysed that there are 17 special sites (1a,1b) and 33 special sites (2a, 2b, 2c) respectively for preservation of species and biotope. Particularly, in case of the No. 27 space, it was assessed that it has the value of about medium (IIIclass) level, but its value was upgraded with the on-spot detailed investigation that most of Aristolochia contorta, designated as a rare plant by Ministry of Environment, is growing. It is regarded that the above-mentioned research result on evaluation of biotope preservation value is expected to provide very important basic materials for future district unit plans and smooth integration with landscape ecology plans and eco-friendly space development.

  • 기후변화에 대응하기 위한 정책 수립과 이행을 위해 온실가스 인벤토리 작성의 중요성이 대두되고 있다. 이에 따라, 토지이용 항목과 변화들에 대해 공간 명시적으로 나타낸 Approach 3 수준의 Land Use, Land-Use Change and Forestry(LULUCF) 매트릭스 구축 필요성이 제기되고 있다. 본 연구에서는 LULUCF 매트릭스의 산림 항목을 중심으로 연속지적도, 중분류 토지피복지도, 임상도, 도시생태현황지도를 활용하여 LULUCF 매트릭스 구축에 적합한 공간정보를 검토하였다. 각 공간정보에 대한 분류 속성 비교를 실시하였고 충청남도 보령시를 대상으로 양적(면적) 비교, 질적(특성) 비교를 실시하였다. 양적 비교 결과 산림의 면적이 임상도에서 최고 50.42%($303.79km^2$), 지적도에서 최저 46.09%($276.65km^2$)의 차이를 보였다. 질적 비교 결과 자료 구축 범위 차이, 자료 구축 목적 차이, 분류 항목 차이, 일필일목의 원칙 적용 여부의 차이, 자료구축 시기 차이 등 5가지 질적 특성의 차이를 확인하였다. 연구 결과 도시생태현황지도가 LULUCF 매트릭스 구축에 가장 적합한 공간 정보로 판단되었으나 전국구축이 되어있지 않은 한계로 토지피복지도가 가장 적합한 것으로 검토되었다. 또한, 도시생태현황지도, 임상도, 토지피복지도 등을 서로 종합하여 LULUCF 매트릭스를 구축하게 될 경우 각 공간정보의 한계를 보완할 수 있을 것으로 사료된다. 추후 전국토를 대상으로 하는 1:5,000 수준의 세분류 토지피복지도 및 도시생태현황지도가 완료될 경우 LULUCF 매트릭스 작성의 정밀도를 향상시킬 수 있을 것으로 판단된다.
