【摘要】 生态足迹是探讨人类持续依赖自然以及要怎么做才能保障地球的承受力,进而支持人类未来的生存的一种可持续评价方法。水资源作为基础性的自然资源和战略性的经济资源,却没有纳入生态足迹模型中,因此生态足迹模型存在很大的不足。 分析水资源特点和生态足迹模型后,在Wackernagel的生态足迹模型中设立第七帐户——水资源帐户,确定了计算水资源帐户生态足迹所需的三个关键参数:全球平均水资源产量、全球均衡因子和地区产量因子,同时确定了水资源生态足迹计算方法,并将水资源生态足迹纳入到了生态足迹模型中,完善了Wackernagel的生态足迹模型。在此基础上以江苏省为例,计算并分析了1998-2003年的水资源生态足迹、水资源承载力以及水资源生态赤字,对江苏省的水资源利用进行了评价。最后,运用纳入水资源帐户的生态足迹模型全面核算评价了江苏省1990-2003年的可持续发展状况。 结果表明,水资源生态足迹计算方法能够很好的和Wackernagel的生态足迹模型耦合,评价结果可以指导水资源可持续利用,保障经济社会可持续发展。更多还原

【Abstract】 The Ecological Footprint (EF) offers a cheap and rapid natural capital appraisal for nations with which human demands can be compared with nature’s available supply for human use. The ecological footprint is an accounting tool that can aggregate ecological consumption in an ecologically meaningful way. It gives us, therefore, a realistic picture of where we are in ecological terms. But unfortunately, it doesn’t incorporate freshwater use into Ecological Footprint by Wackernagel, that’s a great limitation on the assessment for water resources sustainable development.After analyzed the freshwater’s characteristics, based on Wackernaglel’s EF model, the seventh account is studied, defined and summarized, the three crucial parameters including Global Average Yield for freshwater, Yield Factor for freshwater, Equivalence Factor for freshwater are confirmed, calculated. At the same time, the calculation methods for freshwater also are defined, the freshwater account is combined to Wackemagel’s EF model. After that, the freshwater EF is used to assess the sustainable development of water resources on Jiangsu Province from 1998 to 2003, the betterment EF model is used to assess the sustainable development condition on Jiangsu Province from 1990 to 2003.The results show that the seventh account for water resources is reasonable, which proves the freshwater EF model can be used to assess the sustainable development of water resources, and can do well in the betterment EF model.更多还原
