基于二元语义和区间FCM的森林公园生态安全评价方法研究

Research on Ecological Security Evaluation Method for Forest Park based on Two-tuple Linguistic and Interval FCM

由于传统的生态安全评价方法不能处理区间数和语言值,并且安全度等级划分的主观性和随意性较大,评价结果有效性差。基于二元语义和区间FCM的生态安全评价方法,将实数看成区间数的特例,语言数也转化为区间数,FCM聚类方法将区间值转化为语言值,根据最大隶属度原则,对方案集进行分类。将语言值转化为二元语义,将方案集成结果转换为二元语义,利用二元语义的有序性对方案进行排序,既能处理区间值也能处理语言值,分类标准更加客观。

Because the traditional evaluation method for ecological security can＆#39;t deal with interval number and linguistic value, and there are great subjectivity and randomness about the security grade, then the effectiveness of the results is very low. The ecological security evaluation method based on two-tuple linguistic and internal FCM takes the real numbers as a special case of interval number, the number of languages is also converted to interval number, FCM clustering method transforms interval values into linguistic values, according to the principle of maximum degree, the program was set for classification. Converting the linguistic values to two-tuple linguistic, transforming integrated results of the program into two-tuple linguistic and making use of the two-tuple linguistic orderliness sort the program can deal with both the interval value and linguistic value, and classification standard get more objective.
