基于LUCC的喀斯特山区生态系统服务价值评价
|
摘要
喀斯特山区具有特殊的生态环境,对其进行生态系统服务价值评价是保证喀斯特山区生态安全和生态系统恢复的重要基础。该文基于典型喀斯特山区罗甸县土地利用/覆被变化(LUCC)数据,运用土地利用动态度分析研究区土地利用变化情况。结合研究区经济水平,采用"当量因子法"计算研究区生态系统服务价值(ESV),并对罗甸县2009-2016年间ESV的时空变化和驱动力展开研究。研究结果表明:在2009-2016年期间,研究区耕地、建设用地使用面积呈增加趋势,其他的土地利用类型面积均有所减少;研究区生态系统服务价值总体呈下降趋势,除食物生产的ESV增加外,其余的生态系统单项服务价值均下降,其原因主要受控于人文因素的影响;2009和2016年研究区敏感性指数(CS)均<1,说明ESV对价值系数(VC)不敏感,缺乏弹性,因此结合罗甸县县域特征修正后的生态服务价值系数是合理的,研究结果是可信的;受地质背景的影响,罗甸县北部喀斯特地区的生态系统服务价值相比于中、南部非喀斯特地区偏低。因此,在罗甸县土地利用规划中,需要合理调整土地资源结构,提高研究区生态服务价值。
The karst mountainous area has its special ecological environment,and the evaluation of the ecosystem service value in the karst mountain area is an important basis for ensuring its ecological security and ecosystem restoration.The article takes the typical karst mountainous Luodian County as an example,using land use dynamics to analyze the land use change in the research area.And combining the economic level of the study area,the equivalent factor method was used to estimate the ecosystem service value(ESV),and the spatial and temporal variations and the driving force of ecosystem service value in Luodian during 2009 to 2016 were studied.The results indicated that the area of cultivated land and construction land in the studied area showed increasing trend,while the area of other land use types decreasing.The ESV value generally showed a downward trend,in addition to the increase in ESV in food production,the value of the remaining ecosystem services declined.This change is mainly controlled by the effects of human disturbance.In 2009 and 2016,the coefficients of sensitivity(CS) in the study area was less than 1,indicating that ESV is not sensitive to the value of coefficient(VC),and lacking resilience,so the ecological service value coefficient after the correction of the county characteristics of Luodian is reasonable,and the research results are credible.As a result of the geological background,the ESV value of the northern karst area of the County is lower than the central and southern regions.Therefore,for the land use planning of Luodian County,it is necessary to rationally adjust the structure of land resources to improve the value of ecological services in the studied area.
