Sustainable Development Study in Xuchang City Based on Relative Carrying Capacity of Resources

Abstract:

The relative carrying capacity of resources methods was used to calculate the relative carrying capacity of land resources, the relative carrying capacity of economic resources and carrying capacity of integrated resource of Xuchang City during 1978-2008. Study shows that: carrying capacity of integrated resource of Xuchang City is overload, overloading population between 44.2 ~ 1.203 million, showing a "low - high - low" fluctuations; before 1996, land resources is the main capacity resources of Xuchang City, while economic resources become the main capacity resources from then on, mainly due to the decrease of indices of the carrying capacity of land resources. the key factors to restrict sustainable development in Xuchang city is a weak economic foundation and a large population, so Xuchang city should speed up economic development, enhance the carrying capacity of economic resources; control the rapid population growth, improve population quality, make great efforts to achieve sustainable development of resources, environmental, economic and population in Xuchang City
