摘要
洞庭湖位于长江中游荆江以南和湘、资、沅、澧四水控制站以下的平原、湖泊水网区,天然湖泊面积2691km2,洪道面积1481km2。由于泥沙淤积、人类活动的影响,使湖区的水情发生了变化。通过对湖区主要水文控制站的水位流量关系的分析,得到了近四十年来水情变化的一些规律,供有关部门参考。
Dongting Lake is located in the south of Jingjiang River in the middle reaches of the Yangtze River and downstream of hydrologic control stations in Xiangjiang, Zijiang, Yuanjiang and Lishui Rivers, covering the wide alluvial plain and river-plus-lake network region. In this area,there are 2 691 km2 of natural lakes, 1 481 km2 of flood channels. Due to the sediment accumulation and the effect of human activities, the hydrological regime in Dongting Lake area has changed. The hydrological regime change law is proposed by the analysis of discharge-stage relations of main hydrologic stations in Dongting Lake area in this paper.
