摘要
石臼湖作为长江下游的通江湖泊,逐步形成了独具特色的河流湖泊复合生态系统,研究其生态水位对于保障湖泊生物多样性具有重要意义。利用蛇山水位站1973—2020年日均水位过程,分析石臼湖的水位变异特征,结合年保证率法和年内展布法得到逐月最低生态水位,并对水位突变前后的生态水位保障度进行研究,相关成果可为维护石臼湖水生生态系统结构和功能提供数据参考。
Shijiu Lake,as a lake connected to the lower reaches of the Yangtze River,has gradually formed a unique river-lake complex ecosystem.It is of great significance to study its ecological water level for ensuring the biodiversity of the lake.Using the daily average water level process of Sheshan Water Level Station from 1973 to 2020,the water level variation characteristics of Shijiu Lake were analyzed.The monthly minimum ecological water level was obtained by combining the annual guarantee rate method and annual distribution method,and the ecological water level safeguard degree before and after the water level change was studied.The relevant results can provide data reference for maintaining the structure and function of the aquatic ecosystem of Shijiu Lake.
