It is of great significance for the coordinated development of the environment and the economy to study the impact of the human driving factors of land use change (LUC) on ecosystem service value (ESV). In this study, we combined the biomass and remote sensing data of the Lijiang River Basin (LRB), which is a typical karst basin with a fragile ecological environment, to establish an ESV model to calculate the ESV. We also introduced the Lorenz curve and Gini coefficient to further analyze the impacts of the human driving factors of LUC on ESV. The results show that (1) the ESV in the LRB from 1995 to 2015 decreased from 8640.03 million yuan to 8595.38 million yuan, with a total decrease of 44.65 million yuan, indicating that the overall ESV in the region has a decreasing trend; (2) the obvious changes in land use caused a significant loss in ESV and changes in the structure of ecosystem services; and (3) the human driving factors of the total population, GDP, and urbanization rate are inversely related to the ESV in the LRB.
研究土地利用变化(LUC)的人为驱动因素对生态系统服务价值(ESV)的影响,对于环境与经济的协调发展具有重要意义。本研究结合具有脆弱生态环境的典型喀斯特流域——漓江流域(LRB)的生物量和遥感数据,建立了 ESV 模型来计算 ESV,并进一步利用洛伦兹曲线和基尼系数分析了 LUC 的人为驱动因素对 ESV 的影响。结果表明:(1)1995—2015 年,漓江流域的 ESV 从 8640.03 亿元减少到 8595.38 亿元,总减少了 44.65 亿元,表明该区域的整体 ESV 呈下降趋势;(2)土地利用的显著变化导致 ESV 明显减少,生态系统服务结构发生变化;(3)流域内的总人口、GDP 和城镇化率等人为驱动因素与 ESV 呈负相关。
