【摘要】：丰水型城市既有一般城市的水资源承载力特征,又有其一定的特殊性。在分析城市水资源特性及利用方式的基础上,以丰水型城市南京市为例,采用综合评价方法,分析了2006—2010年南京城市水资源承载力的变化过程。结果表明,南京城市水资源承载力总体上呈增长态势,大致处于适载范围内,但承载力有限、波动明显。采用敏感性分析法分析了影响承载力变化的主要因素,进而选择人均GDP、万元GDP用水量、城市人均日生活用水量和污水处理率4项敏感性指标,开展了水资源承载能力提升途径的情景分析。在此基础上指出,提高生产、生活用水效率,节约宝贵水资源,辅以污水处理率的稳步提升是丰水型城市稳定和提升水资源承载力的主要途径,并根据不同城市类型提出了相应的提升建议。
[Abstract]:Water-rich cities have not only the characteristics of water resources carrying capacity of general cities, but also their particularities. Based on the analysis of the characteristics and utilization of urban water resources, taking Nanjing as an example, the variation process of water resources carrying capacity in Nanjing from 2006 to 2010 was analyzed by using the comprehensive evaluation method. The results show that the carrying capacity of urban water resources in Nanjing is increasing in general, which is within the range of suitable load, but its bearing capacity is limited and fluctuating obviously. The main factors influencing the change of bearing capacity were analyzed by sensitivity analysis method, and four sensitive indexes were selected, such as per capita GDP, water consumption of ten thousand yuan GDP, daily water consumption per capita and sewage treatment rate. The scenario analysis of the way to enhance the carrying capacity of water resources is carried out. On this basis, it is pointed out that improving the efficiency of production and domestic water use, saving precious water resources and increasing the treatment rate of sewage are the main ways to stabilize and enhance the carrying capacity of water resources in water-rich cities. According to different types of cities, the corresponding promotion suggestions are put forward.
