生态服务功能损失量化的实践困境及改进路径OA

The scientific quantification of loss of ecological service functions serves as a crucial technical foundation and a key step in determining compensation amounts for ecological environmental damage cases.By benchmarking against the national standard series"Technical Guidelines for Identification and Assessment of Ecological Environmental Damage",this study systematically reviews the methodological framework and assessment indicators for quantifying the loss of ecological service functions.The research highlights three major challenges in current judicial practice:controversies over non-use value assessment techniques,divergences in legal application,and gaps in institutional coordination.The study proposes improvement pathways,including establishing a quantification selection matrix at the levels of standard guidance and practical operation,formulating practical guidelines for non-use value assessment,improving explanatory mechanisms for technical investigators and expert jurors in ecological and environmental damage compensation cases,and strengthening funding support systems for quantification work,thereby facilitating the effective translation of scientific conclusions on loss of ecological service functions into judicial opinions.
