摘要 参照两种典型的生态系统服务价值系数,根据土地利用变化对比研究了长江三角洲经济快速发展区域昆山的生态系统服务价值变化.结果表明:(1)昆山的生态系统服务价值在1994~2001年呈下降趋势,按两种系数计算分别下降了1.22亿元和0.71亿元,相对下降比例分别为4.93﹪和4.12﹪;(2)昆山的生态系统服务价值在评价年份内随时间的变化趋势可分别用线性函数Y1=-121.25X1+17342(R2=0.907)和Y2=-199.62X2+25088(R2=0.906)较好的表示;(3)昆山的生态系统服务价值按两种系数的评价结果均分别与GDP、人口总量和人均GDP指标有较好的线性负相关关系,其中与人均GDP的相关度最高;(4)根据生态系统服务价值与人均GDP之间的线性相关关系式预测表明昆山的生态系统服务价值在未来10a内还将进一步下降,需要采取积极的生态保护措施.采用不同价值系数评价的昆山生态服务价值变化特征相似,但是绝对值相差巨大,由此对生态价值静态评价进行了反思,研究生态系统服务价值变化及其变化的驱动机制更有意义. The value measuring ecosystem services - scientific basis for protection and restoration of regional eco-environment, is directly related to the structure and composition of ecosystems. At broader spatial scales, land use plays an important role in determining ecosystem properties and dynamics. Previous studies have focused more on static assessment of ecosystem services' value but less on its dynamic properties and the underline mechanisms. This paper explored the quantitative measurements of ecosystem service in a fast growing area in the Yangtze River Delta (Kunshan) and examined the changes of these measures with the cover changes between 1994 and 2001. The results showed that: (1) the value of ecosystem services decreased 122 million RMB (4.93%) and 72 million RMB (4.12%) respectively when assessed by the two different indices, (2) The linear changes of ecosystem services' value of the two indices could be modeled with equations Y1 = - 199.62X1 + 25088 (R2 = 0.906)and Y2 = - 121,25X2 + 17342( R2 = 0.907). (3) The ecosystem services' value in this fast growing area in the Yangtze River Delta was negatively and linearly correlated with GDP, population, and GDP per capita, with GDP per capita as the most important predictor. (4) The ecosystem services' value predicted would continue decreasing in the future 10 years, and effective actions are needed to maintain ecosystem services of the region. Finally, it concluded in this study that future studies should pay more attentions on dynamic valuation of ecosystem services' value and the mechanisms controlling the changes of ecosystem services in order to provide useful guidelines for ecology protection and sustainable development.
