Abstract
Based on the concepts of ecological services value index (IESE), economic development index (IED) and social benefit index (ISB), the research used the method of entire-array-polygon diagram index to evaluate the ecological services value of urban green area in Hangzhou between 2005 and 2014 and calculate the comprehensive index of sustainable development of ecological service. The results showed that the total ecological services value of urban green space system in Hangzhou had increased from 1 440.67×106 RMB in 2005 to 2 463.22×106 RMB in 2014; the annual comprehensive indexes of sustainable development of ecological service in these ten years were 0, 0.008, 0.107, 0.341, 0.105, 0.781, 1.020, 0.834, 0.772 and 0.836 respectively. The ability of sustainable development had been fluctuating, showing the trend of increasing first and then decreasing. The relationship among ecological services value index (IESE), economic development index (IED) and social benefit index (ISB) could be described in linear equation: S＝0.912IESE-0.742IED+0.431ISB-0.084. The assessment of the ecological services value of urban green area and the research on sustainable development in Hangzhou will provide reference for optimizing the pattern of urban green space, and sustainable and coordinated development of ecology and economy.
