高速公路边坡生态防护物种选择的模糊多属性决策方法
发布时间：2018-11-20 16:54
【摘要】：高速公路边坡生态防护物种种类繁多,影响因素复杂,评价指标模糊性大,需综合考虑各种因素及其相互关系。通过现场试验、专家评估、文献调研等方法,基于模糊数学和多属性决策理论,建立了边坡生态防护物种评价的二级模糊多属性决策模型。以抗逆性、功能特性、培育特性和生长特性4个指标构建模型,并分别从4个指标出发详细划分第二层次指标,采用模糊数学理论对指标及指标相互间关联性进行了综合评估,以一级模糊多属性决策结果为基础再进行二级模糊多属性决策。该方法成功应用于粤北某高速公路边坡生态防护工程,结果证明了模糊多属性决策方法的有效性和易操作性,为高速公路边坡生态防护的物种决策提供一种新的思路与方法。
[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.
