Research on Dynamic Change of Landscape Pattern and Characteristics Based on GIS and RS in Jinan City

摘要

The landscape pattern information has been obtained in terms of Land sat TM images from 2000, 2005 to 2010 based on techniques of image processing by RS and spatial analysis by GIS. The time-space dynamic change of landscape pattern was analyzed from patches to patterns by some indexes including number of patches, area of patches, mean area of patches, Shannon's diversity index, Shannon's evenness index, Dominance index, contagion, Splitting index. The results indicated:1)The dimension of water land, communication land and unused land was increasing, that is to say, the above three landscape has been fragmented with human's interference.2) The forest and cultivated land which dominated the whole landscape has lost advantage position with the development of land use's diversity and evenness, at the same time, landscape heterogeneity has becoming more and more evident.3) From landscape ecology speaking, ecological environment was in the direction of bad way, because the mean area of patches has increased with building occupying cultivated land, thus, in order to enhance ecological environment quality, we should decrease the influence of human being on landscape and develop region comprehensive ecological effect.
