基于粗糙集和突变级数法的生态经济区划

Study on Eco-economical Zoning Based on Rough Sets and Catastrophe Propression Method

首次采用粗糙集和突变理论相结合的方法进行生态经济区划,建立了较为科学的评价指标体系,确立了应采用的突变模型,采用粗糙集的属性约简算法对粗选的生态经济评价指标进行筛选,运用由突变理论衍生出来的突变级数法对指标进行浓缩,获得生态经济综合评价指标,据此指标进行生态经济区划。以山西省东南部某县的生态经济区划为实例进行区划研究与方法验证,结果与当地实际情况基本相符,表明该区划方法可行。

The method that combining Rough sets and Catastrophe theory together is firstly used in the eco -economical zoning. In this paper, a scientific appraisal target system is established and a appropriate catastrophic model is built. Moreover,attribute reduction algorithm of rough sets is used to filter the primary eco-economical appraisal target and catastrophe progression method derived from catastrophe theory is used to condense the target,and then the comprehensive appraisal target of eco-economy is acquired and used to eco-economical zoning. Besides,this paper applies the method to studying and validating the eco- economical zoning of a country in the southeast of Shanxi Province, and the results accord generally with local realities,therefore,it is proved that the zoning method is feasible.
