| 摘 要： | 通过对甘肃省主要河流径流时空分布规律的分析研究,得出干旱缺水的主要原因是各河年径流丰水时段很短,一般只有2～3年;枯水时段很长,可达7～26年;祁连山区许多河流多年均值基本稳定。并预测从1998年开始至2009年,全省诸河水量从枯水年代转向平水到偏丰的年代;建议全省必须树立长期抗旱的思想,水资源利用必须进行系统分析优化配置。

| Abstract: | We got the main reason of aridity from studying on the time space distribution regulation of runoff of main rivers in Gansu province. That is, for all of the main rivers, annual runoff quantity,plentiful (rich)water period was very short ,generally ,only last 2~3 years; But low water period was very long may last 7~26 years. The average runoff remained steady basically for many years to many rivers in Qilian mountain regions; And we forecasted that the water quantity of all main rivers in whole province will change from low water years to more than normal water years from 1998~2009. The author suggested that everyone should establish a thought of anti drought for long times.The utilization of water resources must be reasonable and optimal arrangements based on systematic analysis. |
