基于改进生态足迹的朝阳市水资源可持续利用研究

分析了传统水资源生态足迹模型的不足,引入水资源可持续利用指数对模型进行改进,计算辽宁省朝阳市2010-2013年水资源生态足迹、水生态承载力、水生态盈亏、万元GDP水生态足迹、水资源生态压力指数、水资源可持续利用指数,并分析朝阳市2010-2013年水资源生态足迹变化及水资源可持续利用情况。结果表明,朝阳市2010-2013年平均人均水资源生态足迹为0.267 2 hm~2,平均人均水资源生态承载力为0.062 5 hm~2,平均人均水资源生态赤字为0.204 7 hm~2,平均万元GDP水生态足迹为0.109 0 hm~2,平均水资源压力指数为4.33,平均水资源可持续利用指数为0.19,水资源利用处于不可持续状态。

Study on Sustainable Utilization of Water Resources in Chaoyang City Based on Improved Ecological Footprint

The traditional water resources ecological footprint model was analyzed, and the model was improved by introducing the water resources sustainable utilization index. Water resources ecological footprint, water ecological carrying capacity,water ecological profit and loss, ten thousand yuan GDP water ecological footprint,water resources ecological pressure index,water resources sustainable utilization index of Chaoyang city during 2010 to 2013 were calculated, and the change of ecological footprint and the sustainable utilization of water resources in Chaoyang city during 2010 to 2013 were also analyzed. The results showed that,during 2010 to 2013, per capita water resources ecological footprint of Chaoyang city was 0.2672 hm2 per capita, water resources ecological carrying capacity was 0.0625 hm2 per capita,water resources ecological deficit was 0.2047 hm2, the average million GDP water ecological footprint was 0.1090 hm2, mean water pressure index was 4.33, and the sustainable utilization index of water resources was 0.19,it indicated that the utilization of water resources was unsustainable.
