中文摘要:

经济与资源环境的协调发展是实现区域可持续发展的重要途径。在简要论述协调度、协调度模型及动态协调度的基础上,给出了协调度的计算方法和等级划分方式。并对陕西省1993-2005年的经济发展与资源环境的协调度、动态协调度进行计算,陕西省经济发展与资源环境协调度从1993年的0.269增长为2005年的0.815,从1993—1995年失调衰退阶段Ⅲ经历了1996--2001年过度发展阶段Ⅱ并最终达到了2002—2005年协调发展阶段Ⅰ;动态协调度由1993年的0.146增长为2005年的0.531,呈持续稳步上升的态势,说明两系统动态协调度较好,趋于协调发展的轨迹上。

英文摘要:

The coordinated development of economy and resource-environment is the key method of sustainable development. Based on the definition of coordinated degree, the model of coordinated degree and the model of dynamic coordinated degree, the authors calculate the value of coordinated degree and dynamic coordinated degree of economic development and resource-environment in Shaanxi province from 1993-2005 respectively, by using principal component analysis method and calculating the index of economic development, the index of resource-environment, the coordinated degree and dynamic coordinated degree as well. The results show: 1) the index of economic development increased from 0.063 in 1993 to 0.699 in 2005 and had significant correlation with all the indicators; 2) the index of resource-environment increased from 0.180 to 0.635, mainly resulted from the going into production of the energy and chemical base in northern Shaanxi Province; 3) the value of coordinated degree went up from 0.269 in 1993 to 0.815 in 2005, the index of economic development from 1993 to 2000 was lower than that of resource-environment, the economic index in 2001 was higher than resource-environment index, the economic index from 2003 to 2005 was always higher than resource-environment index; 4) the value of coordinated degree during this period had experienced three stages:the disorder-recession development stage from 1993 to 1995, the barely coordination development stage from 1996 to 2001 and the coordinated development stage from 2002 to 2005; 5) the dynamic coordinated degree increased from 0.156 to 0.471, showing that the total development was in a good track. The findings reveal that the economic development is increasing rapidly, the coordinated degree is rising gradually, and the development of economic and resource-environment is becoming better as well, but the burden of resource-environment system is growing more serious. Through the analysis of the coordinated degree, the relationship between the economic development
