公路路域护坡工程生态效果评价研究

Evaluation of the Highway Ecological Effects of Vegetation Slope Protection Based on Fuzzy Comprehensive Evaluation Method

影响路域植被护坡工程生态效果的因素复杂多样,具有模糊性和随机性的特点,应用模糊综合评价法进行路域植被护坡工程生态效果的评价,能够克服评价过程中难以确定客观、有效的数学评价方法和主观评价精度低等问题。针对具有多层次、多目标的公路植被护坡工程生态效果评价问题,本文通过模糊综合评价法与层次分析法相结合的方法,得出公路植被护坡工程生态效果结论并确定了影响公路植被护坡工程生态效果的主要因素。

Owing to diverse,fuzzy and random characteristics of the factors affecting the ecological effects of ecological protection slope project,the Fuzzy Comprehensive Evaluation theory was applied to evaluate the ecological effects of vegetation slope protection,which could solve the problems that an objective and effective mathematical evaluation method is hard to determine and subjective evaluation precision is low.Aiming at the evaluation issue of the multi-hierarchy characteristic and multi-criteria of the ecological effects of highway vegetation slope protection,the highway ecological effects of vegetation slope protection conclusions were elicited and main causal factors were determined by combining Fuzzy Comprehensive Evaluation Method with AHP evaluation method.
