摘要
选取8个与植被工程效果紧密相关的评价指标,建立工程实施效果的评价指标体系,评价甘肃藉河流域罗玉沟世行二期项目实施情况。采用层次分析和综合指数相结合的方法,将罗玉沟流域水土保持植被工程实施效果综合指数等间距地划分为5个等级。结果表明:罗玉沟流域植被工程实施综合效果总体处于"良好"等级,但仍存在林分结构布局不合理、草地盖度偏小等问题,结合工程现状提出了今后的改进方向。
Eight evaluating indexes which are closely associated with effect of vegetation project have been selected. Evaluating system has also been established. Five grades have been compartmentalized by methods of analytic hierarchy process and comprehensive index. The results indicate as following： vegetation project of soil and water conservation in Luoyugou watershed is generally adequate. However, a series of problems stiU exist in the project, such as unsuitable structure and arrangement. Based on the situation of the project, useful measures are pointed out.
