The Silk Road Economic Belt area is considered to be one of the typical ecologically fragile areas.
In recent years, with global climate change, surface vegetation, ecosystems, water environment,
growth of animals and plants have been affected to some extent.
And the feedback effect of global climate change in the region is also obvious.
Many researchers have paid attention to this and conducted a lot of research.
With the development of remote sensing technology, regional drought monitoring research has been carried out.
This has important guiding significance for changes in regional ecosystems, soil environment and surface vegetation.
This research will focus on regional drought remote sensing monitoring methods
that has been carried out in the Silk Road Economic Belt area.
