作者通过全球生物多样性信息网络数据库GBIF获取新疆枸杞分布点数据，利用ENMTools工具进行过滤筛选；从WorldClim（2.1）数据库获取19个生物气候变量和3个地形地貌数据，从世界土壤数据库获取9个土壤特征数据，作为环境变量输入MaxEnt模型进行最大熵建模，结合GIS模拟出当前气候条件下植物枸杞在新疆的潜在适生区，得到新疆枸杞土地适宜性评价数据集。该数据集内容包括：（1）新疆枸杞土地适宜性评价结果数据，空间分辨率为30″；（2）新疆枸杞空间分布点数据（引用数据）。数据集以.shp、.tif、.xlsx和.txt格式储存，有16个数据文件组成，数据量为285 KB（压缩为1个文件208 KB）。

They were used as environmental variables and input into the MaxEnt model for maximum entropy modeling. Combined with GIS, we simulated the potential suitable areas of the plant Lycium barbarum in Xinjiang under current climatic conditions, and obtained the Xinjiang Lycium barbarum soil suitability evaluation data set. The data set includes: (1) Xinjiang wolfberry land suitability evaluation result data, with a spatial resolution of 30 \";(2) Xinjiang wolfberry spatial distribution point data (cited data). The data set is stored in.shp,.tif,.xlsx and.txt formats and consists of 16 data files with a data volume of 285 KB (compressed into 1 file 208 KB).
