Analysis of Sustainable Utilization of Water Resources in Guangdong Province Based on Ecological Footprint Theory
摘要
Abstract
Based on the theory of ecological footprint, t he ecological footprint and ecological carrying capacity of w ater resources in Guangdong Province were calculated and analyzed from 2005 to 2011 in aspect of the provincial, regional, and municipal scales. The results showed that ( 1) during the study period, the w ater resources ecological footprint per capit a of Guangdong Province decreases continuously with a rate of 11. 6%/a;( 2) t he water resources ecological footprint per 104 yuan GDP decrea-ses annually, indicating the increasing of ut ilization of w ater resources;and( 3) the w ater resources ecological carrying capacity is high in the provincial scale, which suggested the ecological surplus status and t hus the utilization of water resources is sustain-able. On the regional distribution, the ecological foot print w as highest in the northern mountain area of Guangdong w hereas low-est in eastern Guangdong. The water resources ecological pressure w as highest in the Pearl River Delta region whereas the low-est in northern Guangdong. On the municipal distribution, the water resources ecological footprint per capita was higher in Sha-oguan and Guangzhou than that in other cit ies, and the w ater ecological pressure in Foshan was the highest among al cities. In the process of socio-economic development, the industrial structure should be adjusted and the w ater use efficiency should be im-proved based on the status of sustainable utilization of water resources.关键词
