【摘要】：京津冀城市群是中国在国际经济体系中具有最强竞争力的支撑平台之一,也是中国乃至全世界水安全保障难度最大的地区之一。本文主要以2000-2014年数据为基础,采用泰尔系数、变异系数、曲线分析和空间分级分类分析等方法,揭示了京津冀城市群水资源与用水变化的时空特征。结果显示:1绝大多数城市多年平均水资源总量显著减少,干旱化的长期趋势明显,而且北部、西部城市减少幅度更大;2京津冀城市群水资源极度短缺,空间不均衡性呈现先减小后增大的趋势,而且中部和南部城市水资源开发利用潜力更低,缺水更甚;3绝大多数城市用水总量零增长或缓慢负增长,用水结构以工农业用水比重下降为主要特征,各类用水的空间不均衡性保持相对稳定;4用水效率普遍快速提升,空间分布差异呈现先增大后减小的总体趋势。基于此,建议京津冀城市群实施"以水量城"的城镇化政策和"以水定产"的产业政策,完善水生态补偿政策,落实水资源管理红线政策,实现水资源约束下各城市间经济社会与生态环境的协同发展。
[Abstract]:Tianjin city group is one of the supporting platform China has the strongest competitiveness in the international economic system, and it is also one of the Chinese and the world water security in the most difficult areas. This paper is mainly based on 2000-2014 years of data, using Theil coefficient, variation coefficient, curve analysis and spatial classification analysis, reveals the spatial and temporal characteristics of water with the change of water resources in Beijing and Tianjin city group. The results showed that: 1 the vast majority of the city average annual total water resources significantly reduce the long-term drought trend is obvious, and the north western city, a larger reduction; a severe shortage of 2 Beijing and Tianjin city group of water resources, spatial imbalance decreased first and then increased. But the central and southern city water resources development and utilization potential is lower, more than the total amount of water shortage; most of the vast city of 3 zero growth or slow negative growth, water use structure in agriculture The decline in the proportion of water industry as the main feature, various types of water space imbalance remained relatively stable; 4 water efficiency is improved rapidly, the spatial distribution of the overall trend showed first increased and then decreased. Based on this suggestion, Beijing and Tianjin city group to launch the "urbanization policy of water city" and "water quotas" industrial policy, improve water ecological compensation policy, the implementation of water resources management policy red line, realize the coordinated development of water resources under the constraints of the inter city economic society and ecological environment.
