摘　　要：对石羊河流域1995—2005年水资源利用与经济发展指标进行相关性分析及通径分析,结果表明,农业生产对水资源的压力巨大,必须建立科学合理的水资源利用机制和上中下游协调发展模式,通过生活、工业、农业和生态环境等各用水部门之间协调,使整个区域的水资源得到合理充分的利用,从而达到最大供水效益。研究表明,在经济可持续发展的情况下,人口的增长使得发展林业对水资源的压力巨大,为显著减轻经济和社会发展对水资源的压力,应优先大力发展第三产业,其次发展第二产业、畜牧业和林业。科学分配各产业、各部门的供需水量,实现流域或区域的社会、经济和生态环境的协调发展。Using social-economical data of Shiyang river basin in Gansu province, the authors analyzed the development and utilization of water resources by methods of correlation analysis and path analysis. It was disclosed that agriculture exerts more and more pressure on water resources along with the increase of popu- lation. More population resulted in more farmland and then more water resources consumption. Therefore, it is urgent to establish a scientific and rational water resources use mechanism, making the correlations har- monious among the water use in the upper, the middle and the lower river reaches, and among the water de- mands in departments of living, industry, agriculture and ecology. Consequently, the water use efficiency could be improved greatly in the whole basin. In order to alleviate the population-induced pressure on water resources but keep sustainable development of society and economy, the priority must be given to the devel- opment of the Third Industry, then to the Second Industry and then to the animal husbandry and the forestry; lastly, to realize the coordinated development among society, economy and ecology in the whole basin.
