본 연구는 인천광역시 강화도 지역의 산지형 도시녹지를 대상으로 식생구조 분석을 통한 관리방향 제시를 목적으로 하였다. 총면적 11,331ha에 대한 현존식생 분석 결과 식물군집은 19개 유형으로 분리할 수 있었는데 이중 상수리나무군집, 소나무-상수리나무군집, 신갈나무군집 등 2차림이 전체의 92.32%(10,461ha)를 차지하고 있었다. 아까시나무림 등 인공식재림은 전체의 5.40%(612ha)로서 수도권지역 다른 도시들 보다 적은 면적을 나타내었다. 총 57개 조사구에 대한 TWINSPAN에 의한 classification분석 결과 총 7개 군집으로 분리되었는데 그것은 리기다소나무(군집 A), 상수리나무(군집 B), 소나무-상수리나무(군집 C), 상수리나무-소나무 (군집 D), 소나무-서어나무-졸참나무-상수리나무(군집 E), 졸참나무-신갈나무(군집 F), 느티나무-고로쇠나무 (군집 G)이었다. 강화도 지역은 온대 중부지방에서의 일반적인 천이진행단계인 소나무림에서 상수리나무림을 거쳐 신갈나무림, 졸참나무림, 서어나무림으로 생태적 천이가 진행중인 것으로 파악되었다. 토양 pH는 평균 4.17의 강산성 토양으로서 토양환경 개선을 위한 연구가 산림식생 관리계획에서 중요한 것으로 나타났다.

Urban forest area in South Korea has been increased up to 20.8% of national land as of 2007 by the mergence of municipalities and counties. The rate of park and green tract among urban forest averages out to about 4% nationally but the Capital, Seoul, almost 105% level, not easy to split the two. Park and green has positive management system because of its infrastructure attribute and relevant security obligation standard while urban forest left alone with no such concerns. The most important reason of the negligence comes from institutional inertia although it is possible to be managed functionally by forest laws as like forests of park, landscape, wind and noise protection, and timber product. As a results, it reaches below than 92.64% of the national average level of the timber stockpile especially in the metropolitan areas and loses broad acres rapidly due to the easy conversion system to the urban land usage. Therefore, there must be required some alternative methodologies to conserve and foster it. The paper proposes the four urban forest management types and their control methods. The four types divide into conservation, foster, development, and reservation ones. Also it suggests the five furtherance tract types with the combination among the four earlier types, optionally having one of the six aim climaxes and recommends the standardization of operation design. The total green quantity index of urban forest also suggested by the weight method according to location and DBH class. The case study of the suggested model was executed on the Daejon Metropolitan area and its index calculated as 110.4% level compared with the acreage.

The objectives of this study were to investigate the physical, chemical, and structural characteristics of the stream, especially Mugeo and Yeochon which are being changed to ecological stream by Ulsan city, and to acquire the considerations such as the planning element and plan criteria of the streams for making ecological stream system. Water quality, water quantity, vegetation, instream structures and facilities, and land usage of the streams were investigated and the build up capabilities of ecological stream for the two streams were also analyzed. Planning elements for restoration to ecological stream included physical and biological purification methods in water quality, short term water acquire alternatives in water quantity, and vegetation recovery plan and improvement of habitation environment in ecological system, respectively. Planing elements in physical structures and facilities also included recovery of concrete levee and removal and recovery of covered channel.
