摘要
随着生物资源价值估算方法的日益成熟,生态系统的服务评估成为生态系统研究的热点。运用市场价值、影子工程、碳税法等方法对太湖湿地生态系统的物质生产功能、环境调节功能和文化社会功能等直接与间接价值进行评估。结果表明:太湖湿地生态系统具有巨大和多重服务价值,总价值为112.39×108元。其中,生态环境调节与维护功能价值最大,占总服务价值的48.98%;其次是物质生产与供给功能,占29.1%;文化社会功能最小,占21.91%。通过对9项子功能进行评估得出,调蓄洪水的功能价值最大,约占26.23%,供水功能其次,约占24.56%,气候调节功能,约占18.23%,科研教育价值约占13.16%,植被资源生产功能价值最小,约占0.09%。此项研究首次定量评估了太湖湿地生态系统的服务功能价值,研究成果对于认识太湖湿地的价值,有针对性地保护太湖湿地具有现实意义。
Along with the maturation of estimation methods for biological resource value,the study on the service value of ecosystem becomes a hotspot in ecological field.Through using market value method,shadow engineering approach as well as carbon tax method and so on,this paper attempts to estimate both direct and indirect values of Taihu wetland such as organic matter function,environment regulation function and culture-social function.The results show that Taihu Lake wetland possesses huge and multiple ecological services value,which is about 112.39×10^8 Yuan in all.Taihu wetland has the greatest value in the function of the environment regulatory,accounting for 48.98% of the total.The organic matter production and water supply account for 29.1%.The culture-social function has the least value,accounting for 21.91%.The result of evaluation of 9 subfunctions shows that the most important function is flood regulation which is about 26.23% of the whole value.The second is water supply,accounting for 24.56% and the third is climate regulation,accounting for 18.23%.This study first asseses the value of Taihu wetland ecosystem service from the quantitative prospection.The findings of this study play a significant role in recognization the value of various ecosystem service of Taihu wetland and providing reasonable direction to the protection.
