Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0024] figure 1 A flowchart showing a preferred embodiment of a method of monitoring meteorological drought according to the present invention.

[0025] refer to figure 1 , in step 110, the environmental remote sensing data of the area to be monitored is acquired.

[0026] Here, the environmental remote sensing data may be one or more of precipitation data, vegetation index data, soil moisture data, and surface temperature data in the area to be monitored.

[0027] During specific implementation, precipitation data and vegetation index can be obtained from tropical rainfall measurement satellites, and soil moisture data and surface temperature data can be obtained from advanced microwave scanning radiometers carried by Earth Observation System satellites.

[0028] Considering that only in the vegetation growth area and growth period, the impact of meteorolo...

Abstract

The invention provides a method for monitoring meteorological drought. The method comprises the steps: acquiring environmental remote sensing data of a region to be monitored; determining the comprehensive drought condition index of each image source point in the region to be monitored based on the acquired environmental remote sensing data and the environmental conditions of the region to be monitored.

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...
