基于Meta分析的绿色流域评价指标体系构建研究
Research on the construction of evaluation index system for"green watershed"based on Meta-analysis
摘要
Abstract
The establishment of a scientific and systematic indicator system for"green watershed"is a fundamental prerequisite for achieving sustainable watershed development.This study systematically integrated multi-objective and multi-dimensional indicators from domestic and international watershed evaluation studies using meta-analysis.A comprehensive indicator set for green watersheds was subsequently compiled based on a"Functionality-Integrity-Systemicity"framework.Through correlation analysis and heterogeneity tests,this study revealed the degree of correlation and heterogeneity characteristics between indicators from the three dimensions and the overall green watershed level.The results show that within the Functionality dimension,natural capital indicators such as the vegetation index(R=0.75)and forest coverage rate(R=0.75)exhibited strong positive correlations with the green watershed level,whereas soil erosion(R=-0.47)and the soil and water loss rate(R=-0.50)showed significant negative correlations.In the integrity dimension,the important habitat retention rate(R=0.71)and the large benthic macroinvertebrate diversity index(R=0.71)have a stably high correlation,reflecting the critical role of ecological indicators.For the Systemicity dimension,a positive association was found between GDP per capita(R=0.64),urbanization level(R=0.62),and the green watershed level.Furthermore,subgroup analysis was conducted to preliminarily investigate the sources of high heterogeneity for specific indicators.Based on these findings,the study discusses key challenges in green watershed evaluation,including differentiated assessment,the scale dependency of indicator systems,and the construction of dynamic evaluation frameworks.Ultimately,this research provides a scientific reference for the development of differentiated and precise green watershed evaluations.关键词
