宁夏回族自治区环境承载力评价

Minority Areas of Northwest China are one of the ecological fragile and poverty-stricken regions where are facing with the dual pressures of economic development and environmental protection. So the analysis of the relationship between Environment Carrying Capacity and Environment Carrying States are the preconditions for the coordinated development of economy and environment. This article took Ningxia for example and used factor analysis and vector magnitude method to quantify the Environment Carrying Capacity, Environment Carrying Quantity and Carrying State, and then analysed the evolutionary relationship between economy growth and Environment Carrying Quantity on the purpose of revealing environment effects of economic growth. The results showed that the Environment Carrying Capacity of Ningxia was 0.915 and the environment system presented ideal carrying state, which were weak carrying state(1990-2001) and middle carrying state(2002-2006). However, the fluctuant growh rate illustrates that the economic development pattern are extensive and unsustainable. We considered that the keys of sustainable development of Ningxia are changing the pattern of economic development, readjusting and optimizing industrial structures and continually Intensifying Environmental Protection.
