摘要

通过概化计算得到陕北红碱淖流域1998～2004年的水量补给和消耗

建立了流域水量平衡模型

使用Mat-lab软件建立了多因素线性回归模型

定量分析了红碱淖流域水量失衡的影响因素.研究表明:1998～2004年红碱淖流域年平均补给水量为1.06×10

年平均耗水量为1.69×10

年平均水量净消耗为0.63×10

.自然因素是影响红碱淖流域水量失衡的主要因素.降水量每变化1 mm

对应于水量补给变化约为1.01×10

流域年平均温度波动1 ℃

导致的水量变化约为1.24×10

年平均风速波动1 m/s

造成水量变化约为1.34×10

.流域内农业灌溉是人为因素方面的主要耗水部分

年均约为0.45×10

.由于自然因素的不可控性以及红碱淖流域社会经济的发展

要缓解流域水量失衡状况

必须采取有效措施减少人为因素造成的流域耗水量.

Abstract

Water supply and consumption of Hongjiannao watershed during 1998-2004 were calculated with generalized methods and a water balance model was established. A multiple regression model was set up and the impacting factors of water volume change were quantitatively analyzed with the Mat-lab software. The results indicated that the annual water supply was 1.06×10

and the annual water consumption was 1.69×10

in the watershed. Natural factors were the main driving force to the water imbalance in Hongjiannao Lake watershed. The annual average temperature va

riation of 1 ℃ and the annual average wind velocity variation of 1 m/s would cause the water volume change in the watershed of 1.24×10

and 1.34×10

respectively. Moreover

the precipitation variation of 1 mm would lead to around 1.01×10

of the Lake's water supply change. As a major water consumption of human activities

the annual average irrigation consumed about 0.45×10

water. It seems that some approaches should be adopted to reduce water consumption caused by human activities.
