SDFAI and NEP of China

This dataset contains the short-cycle drought-flood abrupt alternation index (SDFAI) and net ecosystem productivity (NEP) data for China. SDFAI is used to characterize rapid transitions between drought and flood conditions over short time scales, and can identify both the direction and intensity of drought-flood abrupt alternation events. NEP is used to represent the net carbon balance of cropland ecosystems and is an important indicator for assessing cropland carbon sink capacity.本数据集包含针对中国区域的短周期旱涝急转指数（short-cycle drought-flood abrupt alternation index, SDFAI）与生态系统净生产力（net ecosystem productivity, NEP）数据。短周期旱涝急转指数（SDFAI）用于表征短时间尺度上旱涝状态的快速转换，可识别旱涝急转事件的发生方向与强度。生态系统净生产力（NEP）用于表征农田生态系统的净碳收支，是评估农田碳汇能力的重要指标。
