摘要
为了研究水资源利用情况与经济增长的协调性,提出了一种考虑不同受纳水体的水生态足迹计算方法,并以此计算了山东省2003—2015年水量与水质生态足迹,构建了宏观方面的协调发展脱钩评价模型与微观方面的协调度理论,对水资源消耗与经济增长之间的协调关系进行评价.结果表明山东省水生态足迹总体呈现波动上升趋势,水量生态足迹显示出明显的农业主导型;水质生态足迹计算中,地表与地下水质生态足迹比例约为3∶4;地表水质生态足迹中,2003—2009年硝态氮为决定性污染物,2010—2015年总磷为决定性污染物;地下水质生态足迹则表现为硝态氮主导.人均GDP增长与水生态足迹由弱脱钩的初级协调向强脱钩的中级协调转变,初步说明山东省水资源与经济的协调发展呈现改善趋势.
To study the coordination of water resources utilization and economic growth,a calculating method of water ecological footprint was put forward by considering different receptive water bodies.This method was used to calculate water yield and ecological footprint of water quality of Shandong Province in 2003-2015.Macro-level coordinated development of decoupling evaluation model and micro-level coordination degree theory were established to evaluate the coordination relationship between water resources consumption and economic growth.The results show that the water ecological footprint of Shandong Province presents an uptrend of fluctuation overall,and the ecological footprint of water showes obvious agricultural dominance.The proportion of ecological footprint of surface water to groundwater is 3∶4,and in the ecological footprint of surface water,nitrate nitrogen is the deci sive pollutant in 2003-2009,but phosphorus is the decisive pollutant in 2010-2015.The ecological footprint of groundwater is more complicated,which is alternately determined by COD,nitrate nitrogen and phosphorus.The per capita GDP growth and water ecological footprint are transformed from the primary coordination of weak decoupling to the intermediate coordination of strong decoupling.It is basically suggested that the coordinated development of water resources and economy in Shandong Province shows an improved trend.
