Coupling coordination of new rural economic developmentand environmental protection--Evolution analysis based on the data of 1999-2012 of all western regions

Because of the law of interactive stress and dynamic coupling between economic development and environmental protection, the particularity between them should be correctly understood the western region whose ecological environment is relatively fragile, to achieve the coordination of the new rural economic development and environmental protection. Using system science theory and synergetic theory, on the basis of analyzing the basic theory of system coupling coordination about economic and environmental, the article built coupling coordination index system of the new rural economic development and environmental protection in the western region, and established coupling coordination degree model. By taking 1999 which was the starting year of the western development strategy as the starting point, we evaluated the level of the coupling coordination degree of western new rural economic development and environmental protection, and drew the following conclusions: the coupling relation between economic development and environmental protection was strengthening, the coordinated development level was gradually increasing, and its regional internal gap was shrinking each year.
