【摘要】 小流域坡面治理工程优化配置是一个多属性决策问题,但由于信息缺乏,决策往往由专家主观判断,结果依赖专家的经验。采用多种方法对海西海流域的坡面治理进行排序,并对排序结果进行综合分析,识别出林地与水平梯田结合的治理方式为当地坡面治理的最佳措施,解决了不完备信息下的决策问题和单一方法的决策结果随意性问题。研究结果可为当地坡面治理决策提供科学的决策依据。更多还原

【Abstract】 The slope improvement in a small watershed is a problem of multi-attribute decision-making.However,the decision-making is often a subjective judgment due to lack of information,which largely depends on the experience of decision makers.Several multi-attribute decision-making methods are presented to deal with decision problems in slope improvement of the Haixihai watershed under incomplete information and the arbitrary decision by a single method.Constructing woodlands and building level terraces are the most suitable measures for local slope improvement.The result provides the local decision makers with a scientific support in their decision-making.更多还原
