太湖地区贡湖生态修复区生态系统服务价值评估

Assessment of Ecosystem Services Value of Gonghu Ecological Restoration Area in Taihu Lake Area

通过调查2014年太湖地区太湖贡湖生态修复区的基本情况,运用等效替代、生产函数和意愿调查等方法,对修复区的渔业资源、气候调节、净化水质和旅游休闲等服务价值进行了评估,估算出2014年贡湖生态修复区的生态系统服务价值为1 065.3×10~4~1 381.8×10~4元,其中,旅游价值和间接使用价值分别为297.5×10~4~451.8×10~4元/a和588.0×10~4~743.0×10~4元/a,在总服务价值中分别占31%和54%。

The environment of the Gonghu ecological restoration area has been improved obviously in the implementation of the ecological restoration project since 2012. In this study, some quantitative methods, such as equivalent substitution method, production function and contingent valuation method were used to evaluate and analyze the value of ecosystem services based on the basic situation of Gonghu ecological restoration area in 2014. The results showed that the total value of ecosystem services of Gonghu ecological restoration area was 1 065.3 × 104-1 381.8 × 104yuan/yr. The most important function was tourism value and nutrient cycling value was the second one.
