摘要
基于水资源生态足迹模型,结合水资源生态盈余和生态赤字、水资源生态压力指数、水资源利用效率指数与水资源可持续指数,分析了东莞市2000~2011年水资源生态足迹变化趋势和水资源可持续利用状况。结果表明,2000-2011年,东莞市人均水资源生态足迹整体上呈增长趋势,人均水资源承载力总体上呈下降趋势,导致人均水资源生态盈余逐渐减少,并出现生态赤字,东莞市水资源开发利用处于不可持续状态。
Based on water resources ecological footprint model, combined water resources ecological surplus, water resources ecological pressure index, water resources utilization efficiency index and water resources sustainable index, this paper analyzes the variation trend of water resources ecological footprint and the situation of water resources sustainable utilization from 2000 to 2011 year in Dongguan City. The results show that from 2000 to 2011 year, the water resources per capita ecological footprint appears upward trend, and water resources per capita carrying capacity appears downward trend on the whole. So, water resources ecological surplus reduced gradually, and the ecological deficit appeared. The de- velopment utilization of water resources was unsustainable in Dongguan City.
