摘要
为了给黄河流域实施生态环境精细化管理和生态治理差异化管控提供参考,采用“单位面积价值当量因子方法”对黄河流域1995—2020年4类11种生态系统服务的价值(ESV)进行核算,采用Pearson相关分析方法对研究期6个典型年份流域各类生态系统服务之间的权衡与协同关系进行测度,同时借助空间自相关方法对黄河流域进行生态管理分区划定。得出结论如下:1)研究期内,黄河流域的ESV呈增加趋势。就土地利用类型来看,农田、湿地和荒漠的ESV占比减小,而森林、草地和水域的ESV占比的变化趋势则与之相反。供给服务、支持服务和文化服务的ESV占比均呈现减小趋势,而调节服务、支持服务构成了区域ESV的主体。空间上,单位面积ESV在东西走向上呈现“凹”形,在南北走向上呈现“凸”形。2)黄河流域各类生态系统服务之间显著正相关,强协同关系占比为47.27%,表明研究期内各生态系统服务之间成协同关系。3)将黄河流域410个研究单元划分为4个一级分区和13个二级分区,并提出相应生态管理措施。
In order to provide a reference for the implementation of fine ecological environment management and differentiated management and control of ecological governance in the Yellow River Basin,the value of 11 ecosystem services(ESVs)in 4 categories in the Yellow Riv⁃er Basin from 1995 to 2020 was calculated by using the“equivalent factor method of value per unit area”,the trade⁃offs and synergies be⁃tween various ecosystem services in the Yellow River Basin in six periods were measured by Pearson correlation analysis,and the spatial au⁃tocorrelation was used to delineate the ecological management zones of the Yellow River Basin in 2020.The results show that:during the study period,the ESV in the Yellow River Basin show an increasing trend.However,in terms of land types,the proportion of ESV in farm⁃land,wetlands,and deserts decrease,while the trend of ESV changes in forests,grasslands,and water bodies is opposite.The proportion of supply services,support services and cultural services all show a downward trend,while regulatory services and support services constitute the main body of regional ecosystem service value.Spatially,the unit ecosystem service value is concave in the east⁃west direction and convex in the north⁃south direction.Correlation analysis shows that there is a significant positive correlation between the various ecosystem services in the Yellow River Basin,and the strong synergistic relationship accounted for 47.27%,indicating that there is a synergistic relationship be⁃tween ecosystem services in the Yellow River Basin during the study period.The 410 research units of the Yellow River Basin in 2020 are di⁃vided into 4 first level divisions and 13 second level divisions,and the corresponding ecological management measures are proposed.
