【摘要】 文章主要基于生态系统服务价值(ESV)系数研究土地利用对生态系统服务价值的影响。以重庆市为研究对象,对其2007—2016年的土地利用情况进行研究,分析重庆市土地利用变化对生态系统服务价值的影响,同时采用Costanza生态系统服务价值计算方法、敏感性指数(CS)、ESV表对重庆市生态系统服务价值进行研究。通过实证分析可知,2007—2016年,重庆市的林地、水域与建设用地在不断增加,其他土地利用类型在不断减少;且重庆市2016年的生态系统服务价值相对于2007年增长了近60亿元;在生态系统各项服务功能变化中,仅有食物生产略有减低,其余都有上升;采用CS系数对ESV的敏感性进行分析,显示所有地类的敏感度均小于1,证明研究结果具有有效性与可信性。更多还原

【Abstract】 This paper mainly studies the impact of land use on ecosystem service value based on ESV coefficients. Taking Chongqing City as the research object, the land use situation from 2007 to 2016 was studied to analyze the impact of land use change on the service value of ecosystem price in Chongqing. At the same time, Costanza formula, sensitivity index, EVS table, etc., were used to study the value of ecosystem services in Chongqing. Through empirical analysis, from 2007 to 2016,Chongqing’s forest land, water areas, and construction land are rising, and other types of land use are continuously declining;and its ecosystem service value has increased by nearly 6 billion yuan compared to 2007; In the change of ESV, only food production decreased slightly, and the rest increased. Using the CS coefficient to analyze the sensitivity of ESV, it shows that all land types have a sensitivity less than 1, so the results of this study have validity and credibility.更多还原
