长江中下游主要水文站日均水位数据集（1970-1979年）

该数据集在70年代长江中下游历史水文年鉴的基础上进行人工整理，得到包含了各湖区水系水文水位站点的位置、建立年代、所属河流等站点信息，及部分站点的日均水位数据等指标。
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表格文件存放， 1970-1979年共10年各湖区水系共计900多个水文水位站点中部分站点的日均水位数据，含有效条数达169万多条。
数据共享政策为3000条，一个站点的一日数据为一条记录，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 was manually curated based on historical hydrological yearbooks of the middle and lower Yangtze River during the 1970s. It encompasses station metadata including locations, establishment years and affiliated rivers for hydrological and water level stations across various lake basin water systems, alongside daily average water level data and other indicators for a subset of these stations. Classified by lake basin water systems, the dataset is stored in 9 Excel spreadsheet files covering basins such as the Taihu Lake Basin, Poyang Lake Basin and Dongting Lake Basin. It contains daily average water level data for partial stations among over 900 hydrological and water level stations across all lake basin water systems over the 10-year span from 1970 to 1979, with a total of more than 1.69 million valid records. For the data sharing policy: the maximum permitted shared data per application is 3000 records, where one day's data from a single station counts as one record, and each account is restricted to one application per quarter. Please submit your application in accordance with the sharing rules.
