Abstract：
Dry valleys are typical ecologically fragile areas in the Hengduan Mountains, and their environment quality change is of a special indicative significance for regional ecological security. The Yuanjiang dry-hot valley, the Jinshajiang dry-warm valley (Shangri-La-Lijiang section), and the upper Minjiang dry-temperate valley were taken as the study area. Based on land use data from 2000, 2010, and 2020, we constructed a FLUS-InVEST coupled model to analyze the spatiotemporal evolution of historical habitat quality, and set up three scenarios—natural development, cropland protection, and ecological restoration—to simulate the landuse patterns in 2040, to obtain the spatiotemporal evolution dataset of habitat quality and multi-scenario simulation in Yuanjiang-Jinshajiang-Minjiang dry valleys (2000-2040). The dataset includes: (1) geo-location of the study area; (2) land use data at 1 km resolution for each valley under the three scenarios for 2040; (3) spatial distribution data of habitat quality at 1 km resolution for each valley for 2000, 2010, 2020, and 2040 (three scenarios); and (4) statistical data on habitat quality for each valley in different periods. The dataset is archived in .shp, .tif, .xls and .txt formats, and consists of 179 data files with data size of 967 KB (Compressed into one file with 679 KB).
