The relative carrying capacity of natural resources, economy resources and synthetic capacity and their dynamic changes of Anhui Province from1978 to1998 were calculated.

(3)The contribution rate of relative carrying capacity of water resources in relative carrying capacity of natural resources always remains above 50%,water resources plays an important role in the development of Tianjin.

The paper adopts the calculating methods of relative carrying capacity of resources to calculate the relative carrying capacity of land resources, relative carrying capacity of economic resources and synthetic carrying capacity of resources in vulnerable ecological regions of 1990 and 2000 in Yunnan province.

According to the method in term of relative carrying capacity of resources,respectively analyzed relative carrying capacity of resources of Shangqiu City,basing on countrywide and Henan Province s relative carrying index of resources.

This paper uses methods of relative carrying capacity of resources.

Aiming at the characteristics of sample absence and untrue data,the resources capacity and the factor of geographic features were introduced,and the GM-GRNN model for forecasting the size of expressway network was presented.

In the period of economic transformation from economy growth manner to economic development model,it is the important premise and foundation for the main functional regional division and resource carrying capacity to economic development,industrial ecological economy is the profound channel to solve resource scarce and the conflict between economy and environment.

After a overall review of the study of resources carrying capacity,starting from the concept,this paper surveyed the studying process about the resources carrying capacity which was firstly in the field of natural bionomics and then was changed to the fields of applying bionomics and human bionomics.

This paper has used sustainable development index and method of relative resources carrying capacity.
