摘要:
[目的] 量化评价"丹治"工程(丹江口库区及上游水土保持工程)在"十二五"期间实现的总体生态效益,为中国水土保持工程决策和生态效益评价提供新的思路。[方法] 基于灰色关联理论,结合熵值法和层次分析法(AHP)确定评价指标的权重。构建了灰色关联度的TOPSIS评价模型,并采用项目区"水土流失面积"对结果进行了验证。[结果] "丹治"工程初期,水保措施尚未完善,发挥的作用相对较小,生态效益较低;随着各项功能措施的逐步发挥,水土保持生态效益大幅度提升,与初期相比"十二五"末期的生态效益总体增长3.48倍。[结论] "丹治"工程项目区总体生态环境逐步向良性发展,与项目区实际情况相吻合,表明基于灰色关联度的TOPSIS模型对水土保持工程效益评价有较强适用性和可靠性。

Abstract:
[Objective] The overall ecological benefits achieved by the Danjiangkou reservoir area and upstream water and soil conservation project ("Danzhi" project) in the second phase of the five-year project (2011-2015) was quantitatively evaluated, in order to provide a reference for decision-making within China's soil and water conservation project and ecological benefit evaluation.[Methods] Based on the grey relational theory, this paper uses a combination of the entropy method and analytic hierarchy process (AHP) to determine the weight of the evaluation index. Based on this, an improved TOPSIS evaluation model was constructed, and the rationality of the results was verified by using "the soil erosion area" index in the project area.[Results] At the beginning of the "Danzhi" project, the various measures had not been perfected, the functions had been relatively lagging behind, and the ecological benefits were relatively low. With the gradual exertion of various functional measures, the ecological benefits of the soil and water conservation had been greatly improved, and the overall ecological benefits at the end of the fifth year have increased by 3.48 times compared with the initial period.[Conclusions] The overall ecological environment in the area of the "Danzhi" project is gradually developing in a benign way, which is consistent with the actual situation in the project area. Based on the improved TOPSIS evaluation model, it has strong applicability and reliability for the benefit evaluation of soil and water conservation project.
