Abstract

针对黄土高原丘陵沟壑区沟道整治工程造成的下垫面的剧烈变化,通过野外调查、室内试验模拟的方
法,研究了流域沟道不同整治比例(0%、20%、30%、40%、50%)、不同降雨强度(40、60、80、100、120mm/h)情
况下,沟道地表径流流速变化、流域控制工程坝前蓄水变化及对沟道洪水标准的影响。结果表明,随着沟道整
治比例的增大,相对于沟道无整治工程时地表径流平均流速分别减小6.21%、10.95%、19.85%、21.78%,流
域控制工程坝前平均蓄水分别减小3.94%、15.55%、17.23%、23.90%,径流系数由无整治工程时的0.80减
小至0.61。随着降雨强度的增大,平均流速由0.102m/s增大至0.160m/s,流域控制工程坝前平均蓄水与
40mm/h时相比分别增加5.90%、24.17%、30.80%、38.82%,径流系数由0.59扩大至0.81。由此可见,流
域沟道不同整治比例和不同降雨强度对流域控制工程的径流蓄积、径流系数及洪水设计均具有较大影响,实
际工程设计中应考虑其影响,不可忽略。

Other Abstract

Based on the grey system theory,the grey cluster evaluation model of sustainable operation management
performance evaluation of rural drinking water safety project was established.Evaluation index system was developed by
considering indexes from six aspects,including organization management,project management,safety management,economic
management,mass satisfaction,sustainable development ability.The weight of index was calculated by the method
of entropy combination weight,which overcomes the subjectivity of traditional analytic hierarchy process.Taking Daozhen
county of Guizhou Province as an example,the results show that the ranking order of the first order index weights is organization
management,safety management,sustainable development ability,project management,mass satisfaction,economic management;
sustainable management of rural drinking water safety project performance assessment level of Daozhen county is qualified
in 2015,and the grey clustering model and the entropy combination weight method have good scientific and practical in the evaluation
of sustainable operation management of rural drinking water safety project.
