The data set includes: ① MODIS of Zhangye oasis desert transition zone_ NDVI pattern analysis source data: grid data from May to September of each year from 2017 to 2018; ② TCI and NDVI_ Grid source data: three kinds of grid data with different resolutions, with spatial resolutions of 30m, 100m and 250m; ③ Boundary width_ Source data: boundary data of desert, desert, rocky bare mountain and Haloxylon ammodendron, as well as average and standard deviation grid data in March, may, July, September and November; ④ Research scope_ Vector source data.
The source data used for MODIS data is mod09gq data, and the selection condition is the data with daily cloud amount of 0 after effective precipitation from May to September.
Landsat 8 oli data selection conditions are cloud amount 0, vegetation growth period, atmospheric radiation correction first, and then band calculation and analysis.

Landsat 8 oli data selection conditions are cloud amount 0, vegetation growth period, atmospheric radiation correction first, and then band calculation and analysis.
After atmospheric radiation correction, band calculation and analysis are carried out.
MODIS data quality can fully meet the needs of spatial productivity pattern analysis; Landsat 8 oli data can meet the needs of spatial scale effect analysis.
