摘要

[目的] 评价生产建设项目建设期水土保持效果，为水电站水土保持后续监督管理提供数据支撑，为生产建设项目的水土保持效果评价提供参考。[方法] 以生产建设项目——四川省甘孜藏族自治州拉哇水电站为研究评价对象，以生产建设项目水土保持监测重点和监测技术规程为体系框架，应用层次分析法—模糊综合评价法构建包含红线范围扰动、水土流失控制、绿化恢复、水土保持措施实施和水土流失危害5个方面14个水土保持指标的生产建设项目水土保持效果综合评价模型，对拉哇水电站建设中水土保持效果进行综合评价。[结果] 2017—2021年拉哇水电站综合评价指数分别为0.840，0.727，0.571，0.786，0.792，评价等级为优、良、中、良、良，呈现先减小后增加趋势，水土保持效果总体评价结果表现为良好。[结论] 在拉哇水电站建设过程中，包含红线范围扰动、水土流失控制、绿化恢复、水土保持措施实施和水土流失危害5个方面的水土保持工作总体表现良好，收到了较好的成效。

Abstract

[Objective] The soil and water conservation effects of production and construction projects implemented during the construction period were determined in order to provide data support for the follow-up supervision and management of soil and water conservation of hydropower stations

and to provide a reference for the evaluation of soil and water conservation effects of production and construction projects. [Methods] The study was conducted at the production and construction project of the Lawa hydropower station in the Xizang Autonomous Prefecture of Garze

Sichuan Province. The system framework consisted of the focal points and technical regulations of soil and water conservation monitoring of production and construction projects. The analytic hierarchy process (AHP) and fuzzy comprehensive evaluation were applied to establish a soil and water conservation effect evaluation system that included 14 indicators from five aspects (red line disturbance

soil and water loss control

greening restoration

implementation of soil and water conservation measures

and soil and water loss hazards) to comprehensively evaluate the water and soil conservation effect during the construction period of the Lawa hydropower station. [Results] The comprehensive evaluation indexes of the Lawa hydropower station during 2017—2021 were 0.840 (excellent)

0.727 (good)

0.571 (average)

0.786 (good)

0.792 (good)

respectively

indicating a trend of decreasing first and then increasing. The overall result was good. [Conclusion] Soil and water conservation work performed during the construction of the Lawa hydropower station (including red line disturbance

soil and water loss control

greening restoration

implementation of soil and water conservation measures

and soil and water loss damage) performed well overall

and achieved good benefits.
