Analysis on Land Use Landscape Pattern Changes and Driving Force in Hangzhou City
摘要
Abstract
Based on the interpretation of TM images, the theory of landscape-ecology and the method of quantitative analysis, the characteristics and changes of landscape pattern in Hangzhou city during the past 15 years (1991-2005) were analyzed and meanwhile the driving force of landscape changes were discussed based on canonical correspondence analysis (CCA) method. The results showed: (1) The land-use landscape pattern changed greatly, mainly the area of farming landscape and water landscape declined significantly, but the area of building landscape increased, which of 43.85% came from farming landscape; (2) Number of patches (NP) and Shannon's diversity index (SHD1) and fragmentation (FN1) increased, however, the dominance (D) decreased. These results showed that landscape pattern would became smaller and smaller; (3) CCA method clearly demonstrated the correlations and spatial feature between landscape pattern indices and driving forces at eight districts in Hangzhou city.关键词
