摘要
基于成渝地区双城经济圈2010年、2016年、2022年土地利用数据,运用单位面积生态系统价值当量因子法、格网法、空间自相关分析法,对成渝地区双城经济圈生态系统服务价值(ESV)空间格局的动态演化进行定量分析,并继续探究土地利用变化对ESV的影响。结果表明:2010年-2022年间,该区域林地面积增加最多,耕地面积减少最多,土地利用转移以耕地转林地为主。ESV总体呈现增加趋势,表明该地生态环境恢复与保护起到了一定的作用。空间分析显示,ESV在空间上呈现显著正相关,空间格局呈现“中间低四周高”的特征,高值区集中在周边城镇,低值区主要在中心城市。
Based on land use data from the Chengdu-Chongqing Economic Circle in 2010,2016,and 2022,this study employs the unit area ecosystem service value equivalent factor method,grid method,and spatial autocorrelation analysis to quantitatively investigate the dynamic evolution of ecosystem service value(ESV)spatial patterns and explore the impacts of land use changes.Results reveal that from 2010 to 2022,the region experienced the most significant increase in forest area and the most substantial decrease in cultivated land,with land use transfers primarily characterized by conversion from cultivated land to forest.The overall ESV demonstrates an increasing trend,indicating notable achievements in ecological environment restoration and protection.Spatial analysis further unveils a significant spatial positive correlation,with a spatial pattern characterized by“low in the center and high around the periphery.”High-value zones are concentrated in peripheral towns,while low-value zones are predominantly located in central urban areas.
