A Research On The Ecological Footprint Evaluation And Computational Methods Of Urban Water Resourse In Beijing

摘要

Since the water resourse insome towns of Beijing were in a big shortage in the past few years, it becomes a key factor which restricts the sustainable development and theurbanlization of Beijing. Based on the fact, this paper introduces the research situation and development of the ecological footprint of urban water recourse in Beijing. And it puts forward the method for calculating the ecological footprint of urban water resourse, includeing domestic water, process water and ecological water, in Beijing. Furthermore, the computational method of ecological carrying capacity and ecological deficit of urban water resourse in Beijing is proposed, which provides reference for the evaluation of ecological capacity of urban water resourse in Beijing.
