Abstract

Based on TM images of Hangzhou Xixi wetland, two different time classified images were obtained. By using the type of landscape assessment of ecosystem benefit based on City green model and GIS, the Dynamic Change of Ecosystem Benefits in Hangzhou Xixi wetland from 1991 to 2005 was researched. Through the changed table for unit area kind of changing ecological benefit, as well as through the comprehensive analysis of various broad headings area data and the unit ecological benefit of Hangzhou Xixi wetland from 1991 to 2005, the ecology service value in Hangzhou Xixi wetland of the two times respectively were calculated. The results show that the ecology service value in 1991was 80.983 million Yuan, and the ecology service value in 2005 was 46.031million Yuan. It indicated that from 1991 to 2005, the total ecology service value in Hangzhou Xixi wetland's was at a drop condition, the value of declination was 107.888 million Yuan.
