Liaoning is the cradle of the new Chinese industry,as anold traditional industrial base,Liaoning is known as "the eldest son of the Republic".Because of the traditional mode of production.Liaoning province has a lot of ecological and environmental problems,but also brings a lot of social and economic problems.In order to promote the harmony and unity of the natural,social and economic of Liaoning,rational allocation of resources,promote the rational distribution and structural adjustment and upgrading of the industry,we carry out scientific and rational evaluation of regional ecological suitability of Liaoning Province.This paper systematically analyzes the natural environment,economic and social problems at home and abroad,especially in Liaoning province.Through the literature review and data collection,the paper summarizes the concept,evolution and related theories of ecological suitability and ecological suitability evaluation.On the basis of regional natural,social statistical data and field survey,the 3 aspects of nature,society and economy are taken as the overall framework of the study.The evaluation index system of regional ecological suitability of Liaoning province was established based on the comprehensive and typical indexes.A mathematical model of regional ecological suitability evaluation was established by using grey relation projection method.Finally,the regional ecological suitability of Liaoning province was sorted and classified by cluster analysis.The ecological suitability index system layer of Liaoning Provinceis divided into natural ecology,social ecology,and economic ecology 3 categories of indicators,indicators system layer is subdivided into 10 elements layer index,10 factors index again subdivided into 54 layer index layer index.Natural ecological indicators are the most important,followed by social ecological indicators,and the economic ecological indicators.It can be seen that the relative important by the weight of the index.The order of regional ecological suitability in Liaoning Province:1 Dandong,2 Shenyang,3 Benxi,4 Dalian,5 Fushun,6 Panjin,7 Anshan,8 Yingkou,9 Tieling,10 Fuxin,11 Liaoyang,12 Jinzhou,13 Chaoyang,14Huludao.The cluster analysis of regional ecological suitability in Liaoning Province:Dandong as class I,Shenyang and Benxi as class II,Dalian,Fushun,Panjin,Anshan,Yingkou,Tielingas class III,Fuxin,Liaoyang,Jinzhou,Chaoyang,Huludao as class IV.According to the evaluation and comparison of regional ecological suitability,each region in Liaoning can find its own gap and development potential.This is conducive to the control and comparison of natural,social and economic development.In the sustainable development of the future,we should identify the location,make reasonable regional protection,planning and economic management,development strategy,regulation and control of the ecological system,protection of social ecological security.Improve and optimize of regional ecological environment protection from the "source" regulation and optimize the allocation of regional resources and the rational development and utilization.Improve competition strength,and realize the natural ecology,social ecology and economic and ecological sustainable,stable,coordinated and healthy development.At the same time,it can provide reference for the study of ecological suitability in China and other parts of the world. |
