河湖水生态产品价值核算体系的构建及应用

Construction and Application of Value Accounting System for River and Lake Aquatic Ecological Products

水生态系统是生态系统的重要组成部分,具有多重服务价值。本研究结合已有的生态系统生产总值(GEP)核算技术规范,运用层次分析法构建河湖水生态产品价值核算体系,提出相应核算方法,并以云浮市为例,分析河湖水生态产品价值核算体系的运用。经核算,2019年和2020年云浮市河湖水生态产品总值分别为901175万元和678926万元,环比降低222248万元,降幅为25%,降雨量是导致降幅较大的主要原因。

Water ecosystems are an important component of ecosystems,which have multiple service values.Based on the existing technical specifications for calculating gross ecosystem product(GEP),this study uses analytic hierarchy process to construct a value accounting system for river and lake aquatic ecological products,proposes corresponding accounting methods,and takes Yunfu City as an example to analyze the application of the value accounting system for river and lake aquatic ecological products.After calculation,the total value of aquatic ecological products in the rivers and lakes of Yunfu City in 2019 and 2020 was 9011.75 million yuan and 6789.26 million yuan,respectively,a decrease of 2222.48 million yuan compared to the previous period,with a decrease of 25%,and rainfall is the main reason for the significant decrease.
