基于DEMATEL-ANP法的生产建设项目水土保持效果评价
Evaluation of soil and water conservation effect in production and construction projects based on DEMATEL-ANP method
摘要
Abstract
[Background]The effect of soil and water conservation of production and construction projects in flood detention area directly affects the effect of flood control system.The traditional evaluation of soil and water conservation effectiveness is faced with problems such as non-linear correlation between indicators and unreasonable weight distribution.The error rate of the combined method of DEMATEL and ANP in complex system evaluation is lower than that of the traditional model.The comprehensive evaluation of soil and water conservation benefits of production and construction projects is carried out,and the key influencing factors and their weights are identified,which can effectively improve the scientific and practical nature of soil and water conservation decision-making and programming.[Methods]Taking the project of Hudong flood detention area in Shandong province as the research object,the DEMATEL method was used to determine the influence relationship between the index factors,and the ANP method was used to determine the comprehensive weight of the evaluation index.Based on the evaluation of soil and water conservation effect of fuzzy comprehensive evaluation,a network analysis structure including 6 criterion layers and 16 index layers is established,and the evaluation index system of soil and water conservation benefit of production and construction projects is constructed.[Results]1)The soil and water loss intensity grade(c3),soil loss control ratio(c2)and soil and water loss conservation ratio(c1)have high centrality,which are 2.262 0,2.276 and 2.455 respectively,which directly affect the overall evaluation results.2)The ANP weights of the number of occurrences of serious hazard events(h2),the number of disorderly abandoned or downhill slag(w2)and the number of temporary measures implemented untimely and inadequately(m3)are 0.168,0.141,and 0.123,which should be given priority as the core basis for decision-making.3)Waste residue protection ratio(w1),vegetation coverage ratio(m4),forest and grass vegetation restoration ratio(m5)are important indicators to connect the top and bottom factors,and have the function of connecting the preceding and the following in the system.4)The comprehensive evaluation indices of soil and water conservation effectiveness for the Hudong Flood Detention Area Project in Shandong province from 2019 to 2022 were 0.749,0.576,0.823,and 0.712,respectively,with the effectiveness rated as good,moderate,excellent,and good,indicating an overall favorable performance.[Conclusion]The soil and water conservation measures implemented during the construction of the Hudong Flood Detention Area Project in Shandong province have demonstrated commendable performance,yielding significant ecological and hydrological benefits.The DEMATEL-ANP integrated evaluation methodology proves effective in assessing such production-construction projects,as it not only elucidates the interdependent relationships among evaluation indicators but also substantially mitigates the subjective biases inherent in conventional analytic network process applications within decision-making frameworks.The research results can provide reference for the evaluation of soil and water conservation effect of the same type of production and construction projects.关键词
