水生态系统生产总值核算体系及应用

在系统梳理生态系统服务功能及生态系统生产总值核算方法的基础上，聚焦水生态系统，选取2004—2021年相关文献进行统计分析，筛选出水生态系统生产总值核算的3大类14项指标，建立了水生态系统生产总值核算体系，给出了各指标的核算方法及计算公式。以向家坝水电站为例，基于水生态系统生产总值核算体系，评估了向家坝水电站建设对水生态系统生产总值的影响。结果表明，2011—2015年向家坝水电站水生态系统生产总值变化量为261.189 3亿元，其中物质产品价值变化量为111.494 0亿元，调节服务价值变化量为84.815 1亿元，文化服务价值变化量为64.880 2亿元。

Accounting system of gross water ecosystem product and its application

On the basis of systematically sorting out ecosystem service functions and accounting methods of the gross ecosystem product, focusing on the water ecosystem, relevant literature from 2004 to 2021 were selected for statistical analysis. Through screening out 14 indicators of the gross water ecosystem product in three categories, a gross water ecosystem product accounting system was established, and accounting methods and calculation formulas of different indicators were provided. Taking Xiangjiaba Hydropower Station as an example, the impact of the construction of Xiangjiaba Hydropower Station on the gross water ecosystem product was evaluated using the gross water ecosystem product accounting system. The assessment results show that the change in the gross water ecosystem product from 2011 to 2015 was 26. 118 93 billion yuan, including the change in material good value of 11. 149 40 billion yuan, the change in regulation service value of 8.48151 billion yuan, and the change in cultural service value of 6. 48802 billion yuan. © 2023, Editorial Board of Water Resources Protection.
