洪泽湖水位变化趋势和突变分析数据集（1967-2016年）

根据1967—2016年蒋坝、尚咀、高良涧和老子山4个水位站逐日数据，运用小波分析特征水位年际、年内变化规律，通过构建特征水位与同期各入湖、出湖流量及降水量、蒸发量之间的多元回归关系，揭示驱动洪泽湖水位变化的主导因素。

Based on the daily water level data from four hydrological stations (Jiangba, Shangzui, Gaoliangjian and Laozishan) during 1967–2016, wavelet analysis was employed to investigate the inter-annual and intra-annual variation patterns of characteristic water levels. Multiple regression models were established between the characteristic water levels and the concurrent inflow and outflow discharges, precipitation and evaporation of Hongze Lake, so as to reveal the dominant factors driving water level changes in Hongze Lake.
