高速公路邊坡生態(tài)防護(hù)物種選擇的模糊多屬性決策方法
[Abstract]:There are many species of ecological protection for expressway slope, the influencing factors are complex, and the evaluation index is fuzzy, so it is necessary to consider all kinds of factors and their mutual relations. Based on fuzzy mathematics and multi-attribute decision theory, a two-stage fuzzy multi-attribute decision-making model for slope ecological protection species evaluation was established by field test, expert evaluation, literature investigation and so on. Based on the four indexes of resistance, function, cultivation and growth, the model was constructed, and the second level index was divided into four indexes in detail, and the correlation between the indexes and the indexes was evaluated comprehensively by using the fuzzy mathematics theory. Based on the results of first-order fuzzy multi-attribute decision making, two-level fuzzy multi-attribute decision making is carried out. The method has been successfully applied to a highway slope ecological protection project in northern Guangdong Province. The results show that the fuzzy multi-attribute decision making method is effective and easy to operate, and provides a new way of thinking and method for species decision making of highway slope ecological protection.
