本文以官厅水库流域张家口地区为例，针对水资源利用中的问题，对区域现存经济发展模式进行了分析。结合流域长远发展，提出了区域水资源可持续利用的经济发展模式，为流域长期发展规划提供了决策依据。

Regional Economic Development Pattern and Sustainable Use of Water Resources

According to economics,economic development is sure to lead to environm ental pollution.It needs the efforts of government and people including both economists and environm entalists to control the pollution i n a range of allowed limits that environment c an afford.Water pollution in a river basin is mainly caused by unreasonab le economic development pattern.Two o bvious indicators to value the effic iency of water use are production ratio of one unit water in agriculture(i.e.grain output in kg /unit water consumption in m3)and water consumption per 10,000RMB output for industry(namely m3/10,000RMB output ).After a detailed analysis on the pro blems of water use existing in Guanting Reservoir b asin,the present pattern of economi c development and water consumption are discussed in this paper.The two indi ces in the basin are 0.67kg /m3and 160m3/10,000yuan,respectively.Ac-cording to the situations of the basin,the accepted values should be grea ter than 1.0kg /m3and less than 100m3/10,000yuan.From sustainable development point of view,a new developme nt pattern of eco -economy is suggested to enhance economy in the basin scale.The pattern is mainly focused on sustainable use of water resources as we ll as other resources in the basin.
