我国水资源总量为28000×103m3,人均水资源量仅为2100m3,为世界人均水平的28%,预计到2025年,人口增至16×103时,人均水资源量会降到1700m3,将成为用水紧张的国家。因此,在新型城镇化加速建设时期,各地必须加强水资源的保护和管理,尤其是人口密度较大的城市和生态足迹赤字的城市更要通过加强水环境规划、水资源管理体制改革、水污染控制、水源地保护等措施来防微杜渐。文章对我国西部特大中心城市成都的水源保护现状进行分析,通过对成都郫县唐元、三道堰、新民场、安德、唐昌五镇的饮用水水源地走访调查,发现该地区当前面临水源保护和经济发展无法调和的现实矛盾,涉及水源规划、饮水安全、生态补偿、招商引资、农业发展、场镇建设、民生利益等诸多层面。文章研究指出,只有通过落地诸如金融财税支撑、法律法规保障、规划政策调节、生态环境综合治理等一揽子措施,才能在有效保障成都地区用水安全基础上协调推进相关场镇的经济发展和维护城乡居民的民生利益。
The total amount of water resources in our country is 28000 × 103m3 and the per capita water resources is only 2100m3, which is 28% of the world average. It is estimated that by 2025, when the population increases to 16 × 103, the per capita water resources will drop to 1700m3, which will become Water-stressed country. Therefore, during the acceleration of new-type urbanization, all localities must strengthen the protection and management of water resources. In particular, cities with more densely populated cities and deficits in their ecological footprint should, through more efforts in water environment planning, water resources management system reform and water pollution Control, water protection and other measures to prevent micro-gradually. This paper analyzes the present situation of water source protection in Chengdu, an extraordinarily large central city in western China. Through the investigation and investigation of drinking water sources in Tangyuan, Sandao weir, Xinminchang, Ande and Tangchang of Chengdu, we find that the region is currently facing Water conservation and economic development can not be reconciled the reality of contradictions, involving water planning, drinking water safety, ecological compensation, investment, agricultural development, market town construction, people’s livelihood and many other benefits. The article pointed out that only through the landing such as financial and tax support, laws and regulations protection, planning policy adjustment, comprehensive management of ecological environment and a package of measures, in order to effectively protect the water security in Chengdu based on the coordination and promotion of the economic development of the town and the maintenance of urban and rural residents Livelihood benefits.
