黄淮海平原及其附近地区干旱时空动态格局分析——基于标准化降雨指数

Drought, one of the most severe hazards resulting in significant economic loses in agriculture and industry, is a natural phenomenon caused by the imbalance between import and demand for moisture. In the context of global climate change, the drought intensity, frequency, and its spatial patterns have been changing. An accurate understanding of these changing processes would be greatly useful in identifying regional climate change, regional drought forecasting, managing droughts, and ultimately restraining t...
