安吉县生物多样性保护优先区域森林生态系统服务价值核算

Assessment of forest ecosystem service value accounting in priority area of biodiversity protection in Anji county of geography census

森林生态系统为人类提供了生态系统服务,生物多样性是制约森林生态系统服务发挥的关键因素之一。本文以安吉县生物多样性保护优先区为试点区域,分析了现有国内外生态系统服务价值的内涵及核算体系,针对核算的关键难点和问题,以核算体系合理、模型可操作、数据可获取及参数设置科学为原则,构建适用于安吉县的森林生态系统服务价值核算理论技术方法,实现对安吉县生物多样性优先保护区域的生态系统服务价值的空间量化核算。结果显示,2018年安吉县生物多样性优先保护区域森林生态系统服务总价值为65.37亿元,每公顷森林生态系统服务价值在80000元以上。

Forest ecosystem provides human beings with ecosystem services and biodiversity which is one of the most key factor of restricting ecosystem services.Taking the priority area of biodiversity conservation in Anji county as a pilot area,this paper analyzes the connotation and accounting system of ecosystem service value at home and abroad.For calculation of the key difficulties and problems,in order to reasonable accounting system,operational model,data access and parameter settings science for the principle,it builds to applie to Anji county of forest ecosystem service value accounting theory methods,implementation of biodiversity conservation priorities in Anji county area ecosystem service value of quantitative calculation of space.The results show that the total value of forest ecosystem services in the biodiversity priority areas in Anji county in 2018 is 6.537 billion yuan,and the value of forest ecosystem services per hectare is above 80000 yuan.
