2014年浙江省提出了“五水共治”的决策,而2015年正是关键年、冲刺年和深化年,浙江省在提出“五水共治”的同时,也积极推进生态省的建设。水资源可持续利用能力是现阶段需要考虑的重要问题,其动态分析能阐明水资源利用的状况。基于生态足迹法的水资源生态足迹、水资源承载力和水资源动态变化分析研究,可为浙江省水资源利用、管理和规划提供参考依据。结果表明:浙江省2006—2013年水资源生态足迹呈现波动变化的趋势;水资源承载力大于生态足迹,出现水资源生态盈余;水资源生态压力指数处于0~1,安全系数较高;万元GDP水资源生态足迹较高,水资源利用率较低。
Abstract
“A total of five waters treatment” was put forward in 2014 in Zhejiang province, and 2015 is an important year for the strategy.Zhejiang Province advocates the construction of an ecological province, and so the sustainable utilization of water resource is an important issue to be considered at this stage and the dynamic analysis of water resource can present its utilization actuality. Based on ecological footprint method, the analysis of ecological footprint, ecological carrying capacity and the dynamic change of water resources may provide references for water resources utilization, management and planning in Zhejiang Province.The results show that water ecological footprint in Zhejiang Province changed frequently from 2006 to 2013; the ecological carrying capacity of water was larger than the ecological footprint, giving rise to ecological surplus of water; the ecological pressure index of water ranged from 0 to 1, indicating a higher safe factor; water ecological footprint per ten-thousand-yuan GDP was also higher,which proved that water resources in Zhejiang Province was unsustaintable.
