| 摘 要： | 基于RS和GIS技术，选择浙江省嘉兴市为研究对象，采用Costanza生态系统服务价值计算公式，分析了2005年和2010年嘉兴市的土地利用/土地覆盖变化及其所引起的生态系统服务价值的变化；并通过生态系统功能偏离累积模型和不同土地利用类型间的生态服务价值流向阐述了这5年间生态服务价值变化的原因。结果表明，由于嘉兴市城市化和工业化发展迅速，2005—2010年嘉兴市居民点及工业用地面积增加最多，其次是水域，而耕地面积大量减少。由于生态价值系数的差异，增加的生态服务价值并不能弥补损失的价值，致使嘉兴市生态系统服务价值有所下降，从2005年的3283亿元减少到2010年的3131亿元，降低了464％。

| Abstract: | Based on RS and GIS technology， ecosystem service values (ESV) of Jiaxing City in 2005 and 2010 were calculated using the formula put forward by Costanza to identify the influence of land use/land cover changes. Ecosystem function deviation accumulation model and ecological service value flow were adopted to explore possible reasons for ESV changes during the five years. The results indicated that with the rapid development of urbanization and industrialization of Jiaxing City from 2005 to 2010， residential areas and industrial land increased most， and was followed by water area. But， cultivated land decreased dramatically. Due to the different ecosystem service value coefficients of each land use type， the increased ESV could not balance the losses， and consequently led to the decline of the total ESVs from 3283 billion yuan in 2005 to 3131 billion yuan in 2010 reduced by 464％． |
