Application of Technique for Order Preference by Similarity to Ideal Solution Method to Grade Division of Soil Erosion in Construction Projects of Power Transmission
摘要
Abstract
Through the analysis of soil erosion factors,a comprehensive evaluation model for grade division of soil erosion based on the technique for order preference by similarity to ideal solution（TOPSIS）was established by selecting vegetation coverage,surface slope,area ratio of valley to slope,gully density,and area ratio of collapse to slope as evaluation indexes.The grade division of soil erosion was then made according to the evaluation.An empirical study was conducted by taking the development and construction projects of power transmission for an example.Results show that the TORSIS model is simple and convenient,and the result is reasonable.It provides a basis for the relevant departments to develop soil and water conservation planning and its control measures.关键词
