Droughts have emerged as a global problem in contemporary societies. China suffers from different degrees of drought almost every year, with increasing severity each year. are seasonal and can severely impact crops. This study used spatiotemporal trend characteristics analysis disaster data 1991 to 2018 Chinese provinces, addition the Mann–Kendall test wavelet analysis. The included crop damage area, drought-affected area crops, failure area. outputs crops decreased by 10%, 30%, 80%, respectively. population reduced drinking water caused drought, domestic animals were numbered tens thousands. results show that areas owing disasters, mainly distributed northern, eastern, northeaster, southwestern regions. number people concentrated northern These indicators showed general trend. Tibet, Fujian, Shandong, Jiangsu, Anhui, Henan provinces autonomous regions also slightly In particular, Inner Mongolia Autonomous Region clear significant Z-value 2.2629. this research be provide scientific evidence for predicting future trends practising best management prevention resistance.
