石门县生态系统服务价值对LUCC的响应分析
|
摘要
LUCC对维持生态系统服务功能起决定性的作用,是全球环境研究的热点和前沿问题。采用Costanza生态系统服务价值计算方法,在对石门县生态系统单位面积生态服务价值系数进行修正的基础上,探讨了石门县2001—2013年生态系统服务价值对LUCC的响应情况,并构建灰色模型对其发展趋势进行了预测。结果表明:(1)研究期内,石门县生态系统服务价值变化分两个阶段:第一阶段是上升阶段,从2001年的6.500 7×109元增加到2004年的6.519 9×109元,第二阶段是下降阶段,生态系统服务价值从2004年的6.519 9×109元持续下降到2013年的6.507 6×109元。(2)根据预测出的石门县2016—2025年各类土地利用数量情况,得到2025年石门县ESV将减少到6.464 1×109元。同时生态系统单项服务价值出现有增有减的趋势,其中气体调节、气候调节、土壤形成与保护、原材料价值出现下降趋势,而水源涵养、废物处理、生物多样性保护、食物生产、娱乐文化价值出现上升趋势。该文为石门县土地利用与环境保护提供科学依据和技术支持。
Land use/cover change plays a decisive role in the ecosystem services function,which is a hot and frontier issue in the global environment.In the present study,the effects of land use change are discussed based on the obtained values of ecosystem services in Shimen County from 2001 to 2013,and the change trend of land use change is predicted by the methods that the values of ecosystem services proposed by Costanza(ESV)are calculated with regard to the value coefficients of ecosystem services per unit area in the Chinese terrestrial ecosystem,as well as the Gray Model(1,1).The results showed that:(1)during the studied period,the value of ecosystem services in Shimen County was divided into two stages:the first phase was the rising phase that the value increased from 6.500 7×109 yuan in 2001 to 6.519 9×109 yuan in 2004,the second stage was the declining stage that the value of ecosystem services declined from 6.519 9×109yuan in2004 to 6.507 6×109 yuan in 2013;(2)according to the forecast of the amount of land use in Shimen County2016 to 2025,ESV of Shimen County in 2025 will be reduced to 6.464 1×109 yuan.At the same time,the value of ecosystem services is sometimes increasing or decreasing,while the values of gas regulation,climate regulation,soil formation and protection,and raw materials are reduced,and the values of water conservation,waste treatment,biological diversity protection,food production,entertainment and culture appear to rise.This paper can provide scientific basis and technical support for land use and environmental protection in Shimen County.
