Study On Coordination Degree Of Economy And Ecological Construction In Weihe River Basin Of Shaanxi

In recent years, with the rapid development of economy, the ecological environment of the river basin has been severely damaged, along with the economic scale and economic development. The irrationality of the economic development model and the coordination between economic and ecological construction in the process of economic development are the important factors affecting the sustainable development of the basin. Weihe is the "Mother River" of Shaanxi, the west by Baoji, Xianyang, Xi'an and Weinan four cities to the East, the province's 63% population live in Weihe River Basin, Weihe River Basin Economic Development and ecological construction in Shaanxi has great influence on people's living standards and quality of life. Therefore, it is of great theoretical and practical significance to measure the coordination degree of economic and ecological construction of Weihe River Basin in Shaanxi, and to understand and improve the coordinated development of economic and ecological construction of Weihe River Basin in Shaanxi.This paper mainly studies the coordination between economic and ecological construction of Weihe River Basin in Shaanxi. First of all, the paper describes the related concepts and theoretical basis, and combs the related literature at home and abroad, which lays a theoretical foundation for this study. Secondly, this paper analyzes the present situation of the economic and ecological construction of Weihe River Basin in Shaanxi, and analyzes the unity of opposites between the two. Again, the paper constructs the index system of basin economy and ecological construction index system, and introduces the degree of coordination between economic and ecological construction of Weihe River Basin by the economic system, of internal coordination of the internal coordination between the economic system of ecological construction and ecological construction of the watershed two system coordination degree of three parts,including basin economic subsystem and ecological construction subsystem internal coordination degree using the order parameter function to calculate the coordination degree model between watershed economic system and ecological construction system coordination degree using principal component analysis to calculate the regression fitting model and grey relational analysis method, comprehensive method, finally obtains the degree of coordination between economic and ecological construction in Weihe basin in four cities in Shaanxi province the economic and ecological construction, between the four City watershed coordination degree using the arithmetic average method to calculate the economy of Shaanxi River Basin in Weihe Coordination degree between ecological construction and ecological construction. Results: (1)the coordination degree of the complex system of economic and ecological construction in the Weihe River Basin of Shaanxi has fluctuated continuously in 2005-2014 years, but the overall situation has been continuously improved, and the two system is developing in a coordinated direction. (2)the coordination in Weihe basin of Shaanxi Province Economic and ecological construction and development of 2005-2014 is divided into three stages, 2005-2008 years of"coordination" stage, 2009-2011 "weak coordination" stage, 2012-2014 "coordinated" stage. (3)by using the grey relative correlation analysis on five major factors of the coordination degree respectively for city maintenance and construction capital expenditures and the level of economic development, social security expenditure, comprehensive utilization of waste and social investment in fixed assets. Finally, according to the above conclusion put forward economic and ecological construction of the coordinated development of the Shaanxi Weihe basin policy recommendations: to promote stable economic growth; the optimization of the mode of economic growth; increase investment in ecological construction; enhance the comprehensive development capacity of the system.
