摘要
在景观生态学理论和方法的指导下,基于"岛屿生物学理论",从城市屋顶面积、隔离度(如高度、最邻近斑块距离等)这2类因子出发,有针对性地构建了阻力指数(RI)测度城市屋顶景观格局。运用成都市二环路卫星遥感影像和地理信息系统,选取生态中心斑块并构建缓冲区。利用各缓冲区RI的计算结果,将城市屋顶分别规划为3级绿化生态空间发展区,分步骤建设城市屋顶生态斑块网络。
Based on the Theory of Island Biogeography, from urban roof area and the factors that indicate the degree of separation, includingheight and distance of Nearest-Neighbor patch, the paper constructs Resistance Index (RI) that measures the urban roof landscape patternpertinently. The crucial step is to select the ecology center patches and build the buffers by using satellite remote sensing image of SecondRing Road of Chengdu and geographic information systems. Then the urban roofs are planned for three green ecological space developmentalareas by calculated result of RI of buffers and are constructed step by step.
