Spatial Equilibrium of Inter-provincial Ecological Pressure in China

Abstract

There is an imbalance between the ecological pressure and its carrying capacity. One should understand the relationship between people and land to evaluate quantitatively the imbalance and analyze its evolution. Based on the calculation of ecological pressures and its carrying capacity, this paper analyzes China's spatial equilibrium of the ecological pressure and its influence factors by use of the ecological Gini coefficient and the spatial equilibrium index. The results show that China's ecological Gini coefficient is 0.2771 and 0.3779 in 2000 and 2008. The ecological pressure space is relatively balanced, but the imbalance between the ecological pressures and its carrying capacity has been expanded. More central and western provinces belong to "harmonious man-land pattern" and the spatial non-equilibrium factors are mostly contributed by the eastern provinces. The regional difference of the relative relationship between the ecological pressure and the carrying capacity leads to the regional difference of the man-land relationship. In order to coordinate the relationship between human and land in China, it is an important for the regional ecological economic policy to be based on the spatial equilibrium of the ecological pressure.

Key words

ecological pressure / ecological capacity / Gini coefficient / spatial equilibrium / man-land relationship
