关于北方地区水资源模拟方法的探讨

以永定河山区为算例,对北方地区的水资源模拟进行了研究。首先运用分布式水文模型计算了天然径流量,其次通过用水户的供、用、耗、排关系建立了水资源模拟模型,并计算了主要控制断面的径流量和用水户的需水量以及用水量、缺水量以及供水工程的蓄水量、供水量、弃水量等指标。通过模拟计算表明,干流河道控制断面的计算径流量与实测径流量基本吻合,支流河道有一定的偏差。

Investigation on Water Resource Simulative Method of North Region in China

This article investigates water resource simulative method of north in China taking Yongding River Mountain area as example.The investigating process consists of two steps: firstly it calculates natural runoff by means of distributed hydrological model,secondly it establishs water resource model by supply,use,loss,drainage relation of water user,and calculates main channel section runoff and necessary water,useful water,scarce water of water user and calculates storage water,supply water,drainage water of water supply project.Simulated calculation results show that runoff of trunk river is very close to actual runoff while that of branch river exists few difference.
