摘要

水土保持综合评价是水保技术方案及政策可行性评价的基本原则和依据。从水土流失基本情况和水土保持防治效果两方面建立了评价指标体系

采用层次分析法(AHP)和熵权法确定了指标权重

利用因子加权求和法构建了评价模型。以江苏省近5 a典型输变电类生产建设项目为研究实例

运用评价模型进行了水土保持综合效益评价

并针对不同水土保持类型区条件下的输变电项目进行了效益分析比较。结果表明

丘陵区条件下的输变电类生产建设项目水土保持效益最大

其次为一般平原区

最后为平原沙土区;水土保持效益波动性从大到小顺序依次为:一般平原区> 丘陵山区> 平原沙土区。

Abstract

Comprehensive evaluations of soil and water conservation may provide principles and a theoretical basis for the policy development of soil and water conservation and the feasibility assessment of technological scheme. An index system was built based on the two factors of the basic situation of soil and water loss and the protective efficiency of soil and water conservation. An evaluation model was constructed based on factor weighted sum

and the factor weights were determined by using AHP and entropy weight method. By taking the typical power transmission projects in Jiangsu Province for examples and using the evaluation model

the study made a comprehensive evaluation of the soil and water conservation benefits and a comparative analysis of the soil and water conservation benefits for different types of soil and water conservation areas. Results showed that

as for the soil and water conservation benefits in power transmission engineering projects

the hilly area had the greatest beneficial result

followed by the general plains area and the sandy plain area. For the fluctuation of soil and water conservation benefits

the general plain area was the first

the hilly area was the second

and the sandy plain area was the third in a descending order.
