长江中下游主要水文站年均流量数据集（1980-1989年）

该数据集为长江中下游区域各湖区水系的1980-1989年均流量数据，包含了洞庭湖区、太湖区、鄱阳湖区及长江下游干流区等各湖区水系80年代10年900多个水文站点中部分水文水位站点的年均流量数据，在日均流量数据基础上，剔除异常值，均值化处理后得到年均流量数据。
数据集按湖区水系分类，包含太湖区、鄱阳湖区、洞庭湖区等共分9个excel表格存放。
年水文数据共享政策至多10年，5个站点 ，且同一个账号一个季度内限一次，请按照共享原则申请。

This dataset contains annual average flow data of lake basin water systems in the middle and lower reaches of the Yangtze River from 1980 to 1989. It includes annual average flow data from selected hydrological and water level stations out of over 900 hydrological stations across the 10-year period of the 1980s, covering lake basin systems such as Dongting Lake Basin, Taihu Lake Basin, Poyang Lake Basin and the lower Yangtze River mainstream area. The annual average flow data is derived from daily flow data after outlier removal and averaging processing. The dataset is categorized by lake basin water systems, and is stored in a total of 9 Excel files, including Taihu Lake Basin, Poyang Lake Basin, Dongting Lake Basin and other relevant basins. For the annual hydrological data sharing policy: each application is limited to a maximum of 10 years of data and 5 stations, and each account is restricted to one application per quarter. Please submit your application in accordance with the established data sharing principles.
