甘肃省河西地区水资源及其分配的动态模型

The Water Resourles and Its Dynamic Model of Dssignning in the West of Yellow River in GanSu

河西地区有石羊河,黑河和疏勒河三大内陆水系。在此基础上,参照行政区,将河西划分为Ⅰ、Ⅱ、Ⅲ等三个区。根据有关资料,模拟了三个区的技术水平允许农业利用率预测模型,(?)(?)用水(?)年叠加增长速度,畜牧业用水(?)年叠加增长速度和以环境为主的其它用水累年叠加增长速度.并对1990年和2000年的各行用水进行预测。

There are three large in terior river systems in the west of Yellow River of Gansu. That is Shiyang river system, Heihe river system and Shuli river system. Considering this case, we divide the Hexi into three areas, Ⅰ,ⅡandⅢ, through resulting the administrative areas. Tothese atea, according to the statistic data of the every prefecture and city, we have simulatedthe increasing velocities of the water quantity used by agriculture, industry, animal hus-bandry, environment and others, in Ⅰ,Ⅱ, andⅢ ares respectively. And on the basis of thestudy of agriculure using water, we analyse comprehensively the total water used and thewater quantity used by every trades.
