Description

technical field

[0001] The invention relates to the field of ecological and environmental remote sensing monitoring, in particular to a method for monitoring meteorological drought based on environmental remote sensing data. Background technique

[0002] Drought can be divided into four basic types: meteorological drought, agricultural drought, hydrological drought and socioeconomic drought. Among them, meteorological drought is caused by reduced precipitation; agricultural drought is related to insufficient water available for plant growth; hydrological drought refers to insufficient supply of surface and groundwater; socioeconomic drought is related to insufficient supply of some economic commodities caused by other droughts. Compared with the other three types of droughts, meteorological droughts are more frequent and common, and at the same time, meteorological droughts can also cause other types of droughts. Therefore, dynamic meteorological drought monitoring is cruci...
