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。
In the engineering of side-slope ecological protection, there is a wide range of plants with different complex factors. It is difficult to take all the factors and their interrelations into account before determining the slope eco- logical protective species, due to big fuzziness of evaluation factors. Based on the fuzzy mathematics theory and multiple attribute decision-making method, the secondary fuzzy multiple attribute decision-making model for ecological protection species is constructed by means of field test, expert evaluation and a large amount of data. An attempt has been made to establish the model by the four evaluating indicators of stress resistance, functional performance, cultivate characteristics and growth characteristics in view of slope ecological protec- tion effect. Further the four indicators are marked off sub-indexes. The fuzzy mathematics theory is used to evaluate indexes and their correlations for establishing one-level fuzzy multiple attribute decision-making model and then the secondary fuzzy multiple attribute decision making model. The decision-making model is employed to evaluate the slope ecological protection on an expressway in Northern Fujian Province which proves the proposed model effective and easy to operate. The analysis should be considered for the similar ecological protection engineering.
