    摘要:

    [目的] 研究水土流失治理效益评价指标体系、评价模型与评价标准,为国家水土保持重点工程绩效评价、实施效果后评价等工作提供技术支撑。[方法] 采用频度分析法筛选评价指标,采用层次分析法确定评价指标权重。[结果] 提出水土保持工程效益评价指标体系,并构建综合评价模型。模型包含土壤固持与保护、水源涵养、生态改善、收益增加、防灾减灾等5大类15个指标。在此基础上,提出了优秀、良好、缓慢改善、恶化、极度恶化5级评价标准。[结论] 水土保持工程效益综合评价模型涵盖了生态、经济、社会等多方面因素以及各因素之间相互作用关系,可为国家水土保持重点工程实施效果提供直观的、综合的、可量化的评价结果。

    Abstract:

    [Objective] The evaluation index system, evaluation model and evaluation standard of water and soil conservation benefits were studied, in order to provide technical support for the performance evaluation and post implementation effect evaluation of national key projects of water and soil conservation.[Methods] The frequency analysis method was used to screen the evaluation indexes, and the analytic hierarchy process was used to determine the index weight.[Results] The evaluation index system of the benefits of national soil and water conservation projects was proposed, and the comprehensive evaluation model was established. The model included 15 indicators in five categories:soil fixation and protection, water conservation, ecological improvement, income increase, disaster prevention and reduction. Based on this, the evaluation criteria was proposed including:excellent, good, slow improvement, deterioration and extreme deterioration.[Conclusion] The comprehensive evaluation model for soil and water conservation benefit evaluation covers many factors such as ecology, economy and society, and it also covers the interaction relationship between different factors, which can provide intuitive, comprehensive and quantifiable evaluation results for the implementation effects of national key soil and water conservation projects.
