摘要
为了分析一个地区人们实际消耗的水资源量,借鉴生态足迹理论,构建了水资源足迹计算模型,以分析判断该地区的水资源盈余情况。根据武汉市的统计资料,确定了针对该区域模型中的水资源均衡因子和地区产量因子2个关键参数,并计算了武汉市2003～2008年水资源足迹和水资源承载力,引入水资源足迹指数、万元GDP水资源足迹等指标,对武汉市水资源持续利用状况进行了定量评价。分析评价结果表明:就本地产水而言,水资源状况由弱不可持续利用向不可持续利用发展,但由于武汉市过境水量大,可有效解决水资源短缺状况。
Based on the ecological footprint theory,the computational model of water resources footprint is established to analyze the practical consumed water quantity in a certain period and area and identify its surplus condition in the area.According to statistical data of Wuhan City,two key parameters of equivalent factor and local runoff yield factor of water resources are determined in the model and the water footprint and water resources bearing capacity of Wuhan City in the period of 2003 to 2008 are computed.The water footprint index and ten-thousand Yuan GDP water footprint index are introduced to quantitatively evaluate the sustainable utilization of regional water resources in Wuhan.The analysis results show that as far as local runoff yielding,the water resources in Wuhan area has a variation tendency from weakly unsustainable utilization to unsustainable utilization,however,large incoming flow can effectively mitigate the water resources shortage condition in the city.
