Rough Set And Catastrophe Series Approal In The Ecological And Economic Zoning Of The Applice Research

With the rapid economic development and ecological environment and the contradiction between economic construction highlight the growing problem, the coordination of economic development and the relationship between environmental protection and seek to achieve sustainable socio-economic development and people to coordinate an effective way to coexist, ecological economy Planning Study on the rise of the environment an important aspect of scientific research. Ecological and economic zoning is the most fundamental method of determining division of this study to focus on ecological theory and economic planning methods, and explore rough set theory and catastrophe theory in the application of ecological and economic zoning of the possible, Set Theory into a specific ecological and economic zoning technical methods can not only strengthen interdisciplinary knowledge infiltration, more importantly, the two sides can promote the theory of perfect, upgrade their technology, their research has certain theoretical value and practical significance.This study and the analysis of mutations of rough set theory on the basis of the rough set of attribute reduction algorithms to simplify indicators, the indicators further evaluation to determine the ecological elements of the mutant series model, as well as evaluation of Rough Set Division, layer by layer, gradually rough set theory and the specific mutation, formation of ecological and economic zoning of the Rough Set Series system and mutation method, to some extent, rich ecological and economic zoning of the theory and techniques.This study is part of the mutation theory derived from the mutant series method, applied to specific ecological and economic elements of the evaluation process, and the mutation of a series of improved to a certain extent. Mutation of a series of major ecological and economic evaluation of the process is specific: the use of rough set attribute reduction algorithm, a system of indicators to remove redundancy reduction targets. Rough Set in accordance with the method of calculation of the importance of the relationship between the indicators, in accordance with the importance of the different mutations identified in the series of important variable model and secondary variablesThe second is the content of this study will be rough set theory and catastrophe theory into specific ecological and economic zoning method. Based on rough set of attribute reduction algorithm as a screening method of knowledge, as a mutation series model concentrated knowledge, the formation of a final for the classification of knowledge, the use of the indiscernibility rough set theory, zoning, ultimately forming A classification system based on knowledge of methods. As an example, this paper Yangcheng County targeted mutation test series method to improve the practical effects of the existing conditions, the Yangcheng County collection of the relevant information. Established a three-tier structure of the index system, application mutation series model integration of the ecological and economic evaluation, in accordance with ecological comprehensive economic level and 17 in Yangcheng County area townships as the basic unit, the Rough Set Application Clustering Method its of a five zones. Contrast actual situation indicates that the class is strong and the differences between the categories are similar to those of the ideal results.
