Abstract: Abstract：China is one of the countries suffered many serious natural disasters which have serious impact on crops and cropland as a big agricultural country. In this study, we use metrological, Morlet wavelet and spatial analysis methods to analyze the spatial-temporal distribution characteristics of China’s crops and cropland suffered natural disaster, and to investigate the periodicity of crop suffered natural disaster area, and the relationship between the areas of crop and cropland suffered natural disaster and temperature, precipitation and topography based on the statistical data of the areas of crop and cropland suffered natural disaster from 31 provinces (autonomous regions and municipalities directly under the central government), and combined with meteorological data (temperature, precipitation…) and topography. The results show that the crop suffered disasters were mainly caused by droughts and floods from 1978 to 2017, the areas of crop and cropland suffered natural disaster are shown downward tendency, moreover, there is significant change period about 30 years for crops area suffered disaster. Meanwhile, there are differences in the spatial distribution of different disasters. Among these, the crops’ areas with large areas affected by natural disasters are mainly more developed areas of agriculture such as the North China Plain, the Northeast Plain, and the middle and lower reaches of the Yangtze River. Cropland areas suffered natural disasters are mainly distributed adjacent to the provinces (municipalities and autonomous regions) on both sides of the Hu Huanyong line, and the southwest of China is the most serious region. Floods, landslides, mudslides are the main reason which cause the cropland areas suffered natural disasters. There are positive, negative, negative, positive and positive correlations in the confidence interval between crop’s drought, flood and precipitation, crops’ freezing and temperature, cropland suffered natural disaster and average slope, slope is higher than 15 degrees. This study has an important significance for reducing natural disaster losses and improving defense disaster capabilities by studying the spatial-temporal characteristics of crops and cropland suffered natural disaster in China. By studying the spatial-temporal characteristics of crops and cropland affected by natural disasters in policy design, it will be an important significance for reducing natural disaster losses and improving our national defense disaster mitigation capabilities.
