赣州市2010-2020年生态服务价值当量影响变化分析

Analysis on the Changes of the Equivalent Value of Ecological Services in Ganzhou City From 2010 to 2020

以土地利用数据、统计年鉴数据以及行政区划数据,运用生态系统服务价值当量模型计算得到赣州市不同时间段的生态系统服务当量,并以此变化为依据,分析了赣州市2010-2020年的生态系统服务价值当量的变化原因,结果表明:2010-2020年赣州市生态系统服务价值从1347.90亿元上涨到1941.73亿元,其中2010-2015年增长了585.67亿元,主要原因是因为赣州市2015年的粮食播种面积和产量增加,增加了土地的实际经济效益。基于此,提出了赣州市生态建设管理建议与对策。

Based on land profit data,statistical yearbook data,and administrative division data,this paper utilizes the ecosystem service value equivalent model to compute the ecosystem service equivalent of Ganzhou City during different time periods.Furthermore,it analyzes the causes behind changes in the ecosystem service value equivalent of Ganzhou City from 2010 to 2020 based on these alterations.Finally,this study proposes ecological construction management suggestions and countermeasures for Ganzhou City.This paper concludes that the value of ecosystem services in Ganzhou City increased from 134.79 billion yuan to 194.173 billion yuan from 2010to 2020 with an increase of 58.567 billion yuan from 2010 to 2015 primarily due to an expansion in sown areas and grain output which augmented actual economic benefits derived from land.
