Index System And Modeling Of Regional Ecological Civilization Construction Evaluation

In recent years, the construction of ecological civilization is gradually into a top-down consensus, theoretical research and practice have made considerable progress. The importance of ecological civilization evaluation is becoming increasingly prominent, and attracted widespread attention in academia. However, most studies evaluated only one area of regional ecological civilization construction, and the comprehensive and detailed study that look at the construction of ecological civilization into a complex system is relatively rare. Research on the theoretical system of ecological civilization is more and more, at the same time, the empirical and guidance research are fragmented and fragmentation. Many studies have determined subjectivity index system and have appeared serious homogenization, and the studies that based on the characteristics of the data itself and reflected the ideology of regional differences have not yet appeared.How to evaluate the ecological civilization construction achievements scientifically in background of regional differences has become a critical proposition which impact on regional development. This study starts from four aspects that is Economy, society, ecology and environment respectively, putting index selection as the foothold, seeing differentiated evaluation as the main line, putting model building as a means. On this basis, the quantitative index system of regional ecological civilization construction is constructed. Evaluation of regional ecological civilization is study in depth from the two different levels of time-space and static-dynamic, by a combination of theoretical research and case studies and comprehensive use of various econometric analysis models.Through research, the following results and conclusions were obtained:(1) The connotation and characteristics of ecological civilization is clear by theoretical analysis, the key issues of evaluation of ecological civilization construction are understood in depth, and the essential characteristic of ecological civilization construction is analyzed. This provides a guiding principle for the index selection and filter in the late.(2) After lessons relevant indicator system at home and abroad, the theory and the scientific method to support the index system of ecological civilization construction are studied. After multi-disciplinary considerations, an index library of regional ecological civilization construction that able for most of the region is established. It provides differentiation evaluation criteria and alternative indicators.(3) By adding the neural network model to index selection process, a nonlinear index filter model was established. It is able to pick out indexes suitable for regional characteristics from alternative library, realize the objective to select indicators, and thus evaluate different target from different regions.(4) For defects existing evaluation models, by building set pair analysis models, spatial statistical analysis models and cellular automata model, from the static evaluation, spatial analysis and trend deduced three angles, different ecological civilization evaluation model are constructed and the information contained in the index system was exhumed.(5) After selected Yangtze River Delta area as a typical study area, this study filtered index with model and constructed the index system suitable for regional characteristics. Analysis showed that the indexes from the total economy class are weakened, the index reflecting the change of industrial structure is more important, and the contribution from the ecological and environmental class is lower in ecological civilization construction evaluation of the Yangtze River Delta. Then, a comprehensive evaluation of the ecological civilization construction in Yangtze River delta area is given based on three types of models. The results show that the overall level of ecological civilization construction at Yangtze River Delta region is high, intraregional differences is big, the distribution has a significant spatial autocorrelation, and the overall development trend is good.This study presents the differences evaluation mechanisms of ecological civilization construction from the theoretical level, Improves the theoretical system of ecological civilization, and provides a scientific decision-making to accelerate regional ecological civilization construction and regional co-coordinative development. From the research methods, this paper first proposed the construction of an alternative indicator database and use neural network model to improve the accuracy and objectivity of index Filter. With temporal analyze perspective, a comprehensive evaluation of regional ecological civilization construction is given by combined a variety of models. It enriches the research means of regional ecological civilization construction, and provides technical support for scientific planning and regulation of regional ecological civilization construction.
