摘要
以陕西省关中地区引汉济渭调水工程为例,采用层次分析和效用函数计算模型相结合的方案优选方法,计算该地区拟采用的三种调水方案的综合量比值。通过对三种方案评价结果分析发现,对国家南水北调中线调水工程影响最小,工程可实施性和经济性较好的调水方案综合量比值最大,为最佳调水方案。该结论与引汉济渭调水工程的初步推荐方案相一致。效用函数与层次分析法相结合的调水方案优选方法不但包含了评价系统所包含的数据信息,较好减免了人为因素对方案决策的影响,而且更能全面、客观地反映实际情况,因此,其是较为理想的跨流域调水方案优选方法。
Taking the water diversion from the Hanjiang River to the Weihe River in Hanzhong of Shaanxi for example,calculation was made of the aggregative quantity index number of three water diversion schemes by combining analytic hierarchy process（AHP） with computation function model.After comparing the three outcomes of water diversion schemes,it is definited that the middle route project of South-to-North water diversion is the best plan,which has the least influence on the environment and the maximum aggregative quantity index number which included more practicality and better economic benefit.The method,combining analytic hierarchy process（AHP） with computation function model,consists of all the information for the evaluation system,prevents the artificial influence and reflects completely the practical situation,wich is regarded as an ideal optimization plan for the inter-basin water transfer projects.
