Wuliangsu Basin,ecological vulnerability,long time series


The Wuliangsu Lake and its surrounding area is in the western part of Inner Mongolia, China. Its geolocation is between 106°24′23″ E and 109°48′13″ E, 40°11′18″ N and 41°14′44″ N, with an area of about 1.47x104 km². Based on the Google Earth engine platform, we constructed an ecological vulnerability evaluation index dataset through the SRP model. In order to avoid the influence of the water in the study area on other indicators, all the original data were masked using the land cover data in 2020. In addition, this dataset has been standardized with a range of [0, 1]. The smaller the value, the lower the ecological vulnerability is, and vice versa. The spatial resolution of the ecological vulnerability is 30 m. The dataset is archived in .shp and .tif formats, and consists of 71 data files with data size of 4.1 GB (Compressed to one file with 1.08 GB). The analysis paper based on the dataset was published in Journal of Geo-information Science, Vol. 25, No. 10, 2023.
