摘    要:以上海市为研究区域,以遥感与地理信息系统为技术手段,基于2003年航空影像,分别按照景观类型和斑块大小两方面对城市绿地景观进行了类型划分,建立了城市绿地景观空间数据库;并将研究区域划分为8个空间单元,运用景观生态学以及空间分析方法,分别从斑块水平、类型水甲、景观镶嵌结构等方面研究了上海市城市绿地景观格局的总体布局特征;选择斑块数量、斑块血积标准差、面积均值、周长均值、分维数等若干景观生态学指数来研究城市绿地景观镶嵌结构的数量特征,探讨了城市绿地景观在城市扩展与城市景观格局演变过程中所呈现的时空规律,旨在为城市规划与发展提供决策依据.

关 键 词:城市绿地  景观  空间格局  数量特征  上海市

Abstract:Based on the GIS and aerial images of 2003a, this paper studies the spatial pattern of urban green landscape of Shanghai via landscape ecological theory. The green landscape was consists of several kinds according to landscape type and patch size. The spatial database of green landscape was built in MYSQL. The research area was divided into eight units. General distribution characters of urban green landscape was discussed at the level of landscape patch, landscape type and mosaic based on the theories of landscape ecological and spatial analysis. Several ecological indices of landscape, such as patches number, standard deviation of area, average area, fragmentation index and so on, was selected to research the quantitative characters of mosaic structure of urban green landscape. The main purpose is to reveal the spatial and temporal characteristics of urban green landscape during urban expansion and to provide decisions supporting for urban developing, managing and to solve urban ecological and environmental problems.
Keywords:Urban green land  Landscape  Spatial pattern  Quantitative characteristic  Shanghai
