湘江长沙段枯水期水位变化及其影响研究

Research on the Water Level Variation of Xiangjiang River in Changsha in the Dry Season and Its Influences

湘江是长沙的母亲河,长沙的发展得利于湘江的恩泽.但近几年来,湘江年年出现特枯水位,特别是2007年以来,长沙站最低水位逼近25.1米的供水警戒线.以湘江2010-2011年度枯水期长沙段水位变化为重点进行分析,并把多年来长沙站出现的最低水位与近几年出现的情况进行比较分析,得出近年来湘江长沙段枯水期的水位变化趋势.最后分析了湘江长沙段枯水期水位走低的各种影响.

Xiangjiang River is the mother river of Changsha, whose development is in the favor of Xiangjiang River. But in recent years, extreme low water level appears almost every year in Xiangjiang River; especially since 2007, the lowest water level of Changcha is close to the warning level of water supply, which is 25. im. This paper focuses on the water variation of Ximlgjiang River in Changsha in the dry season during 2010 - 2011, and compares the lowest water level of Changsha appeared in past many years with that in recent years, and obtains the trend of the water level variation in recent years. The paper also focuses on the impacts of the trend of the water level becoming lower of Xiangjiang River in Changsha in the dry season.
