Differential characteristics of disaster index and disaster area index
The two high-value areas are concentrated in North China,
Jianghuai and South China.
The former ranges from north to west and the latter is from south to east.
Jianghuai region, is the double highest region.
Qinghai and Tibet are the lowest value regions in the whole country,
and the low value regions in Zhejiang and Guizhou - Guangxi are the two low value regions.
The difference of the disaster index is more significant than the disaster index.
Although there is a close relationship between disaster and disaster,
it is mainly related to the scale, mode,
degree of human activities in land use and the ability of anti - disaster.
