The Time-Series Study of Xiangjiang River Water Carrying Capacity Based on the Ecological Footprint of Water Resource — The ChangZhuTan Region, for Example

Abstract:

This paper is based on "the method of ecological footprint of water resource" and through establishing "ecological footprint of water resource" model to analyze the water resources utilization of ChangZhuTan region, Xiangjiang River. Time-series is applied to researching the water resources utilization of ChangZhuTan region , Xiangjiang River from 2003 to 2009. Meanwhile, the indicators like ecological footprint of water resource and so on in the following 6 years are predicted. Ecological footprint of water resource per ten thousand yuan GDP is introduced to analyze the water utilization efficiency of ChangZhuTan Region, Xiangjiang River quantitively. The result shows that, from 2003 to 2009, the water resources of ChangZhuTan Region, Xiangjiang River is in the state of ecological Surplus, but the ecological surplus value decreases year by year, which means that the sustainable utilization of Xiangjiang River is getting worse. The prediction also shows that the ecological footprint of water resource per ten thousand yuan GDP will increase year by year in the next 6 years, which means that the water utilization will be less efficient.
