本数据集针对青藏高原荒漠区的高寒气候特点，以我国青藏高原柴达木盆地为调查核心区，兼顾青藏高原阿里高原谷地等区域，于2017-2021年，调查了分布在这些区域的垫状矮半灌木高寒荒漠、多汁盐生矮半灌木荒漠、半灌木-矮半灌木荒漠、灌木荒漠等植被类型。调查的主要植被群系包括：藏亚菊高寒荒漠、垫状驼绒藜高寒荒漠、唐古特红景天高寒荒漠、盐爪爪荒漠、小叶金露梅荒漠、帕米尔麻黄荒漠、膜果麻黄荒漠等。
“荒漠植物群落及生境数据库”的说明文档，对应数据库中的样方数据和土壤信息。
调查区域分为三个片区，其中，西藏阿里地区30个调查点、柴达木腹地295个调查点位，柴达木盆地东北部35个点位。调查中，在对青藏高原荒漠区的主要植物群系调查的同时，采用无人机对群落生境进行了调查。
无人机拍摄高度分别为10 m、30 m、50 m、70 m、90 m米和 110 m，除13个军事管控区禁飞区点，共获得无人机照片1893幅。群落生境无人机图像录入中国荒漠植物群落数据调查。通过照片可以看到样点所处的地形部位、地表河流及冲蚀沟壑植被相对盖度等生境状况。

This dataset focuses on the characteristics of the alpine climate in the desert areas of the Qinghai Tibet Plateau. Taking the Qaidam Basin of the Qinghai Tibet Plateau in China as the core area of the survey, and taking into account areas such as the Ali Plateau valley of the Qinghai Tibet Plateau, vegetation types such as cushion shaped dwarf and semi shrub alpine desert, juicy halophytic dwarf and semi shrub desert, semi shrub dwarf and semi shrub desert, and shrub desert distributed in these areas were investigated from 2017 to 2021. The main vegetation formations surveyed include: Tibetan Chrysanthemum Alpine Desert, Cushioned Camellia Ceratoides Alpine Desert, Tanggute Rhodiola Alpine Desert, Salt Claw Desert, Xiaoye Jinlumei Desert, Pamir Ephedra Desert, Film Fruit Ephedra Desert, etc
The explanatory document for the \"Desert Plant Community and Habitat Database\" corresponds to the sample data and soil information in the database
The survey area is divided into three areas, including 30 survey points in Ali, Xizang, 295 survey points in the hinterland of Qaidam, and 35 survey points in the northeast of Qaidam Basin. During the survey, while investigating the main plant communities in the desert areas of the Qinghai Tibet Plateau, drones were used to investigate the community habitats
The drone shooting heights were 10 meters, 30 meters, 50 meters, 70 meters, 90 meters, and 110 meters, respectively. Except for 13 military control zone no fly zones, a total of 1893 drone photos were obtained. The drone images of community habitats were input into the survey of desert plant community data in China. Through the photos, we can see the terrain, surface rivers, and relative vegetation coverage of eroded gullies where the sample points are located
