The Study of Land Use Change on the Landscape Impact of Urban Water in Taihu Lake Basin - A Case Study in Urban Suzhou

Abstract:

Integrated using GIS technology, the relevant principles of landscape ecology and hydrology, and choosing the landscape index such as patch number, patch area, patch density, fragmentation index, separation index and connectivity index, etc. to analyze the changes of urban water landscape in urban Suzhou. The results showed that: 1) The past 15 years, the area of the water landscape in the study area had decreased from 16.18 km2 to 5.21km2; 2) During 1980s to 2009, the patch number of the water landscape had increased, the average patch area had decreased, but the patch density, the patch separation and the fragmentation index had increased. This fully reflected the level of the water landscape fragmentation continued to increase in the study area; 3) During 1980s to 2009, the connectivity index had decreased from 0.7 to 0.44 in urban Suzhou; 4) From 1980s to 2009, the water rate had decreased about 66.21%. It leaded to the regional channel storage capacity had reduced approximately 318.44×104m3, and the per unit area of regulation and storage capacity had decreased nearly 2.25×104m3／km2.
