数据文件为7z压缩包格式，可用7-Zip软件解压打开，内部分为2个压缩包，包括2020年川藏地区30个样点、青海省果洛州30个样点的调查照片，每个样点的照片放置在单独的一个文件夹内，文件夹命名为样点的编号，每个文件夹后的日期为采样日期，每个样点的照片包括采样点周围的景观照片，采样样方内植物群落的照片以及优势种的特写照片，可观察到样方内植被群落状况，土壤表面状况以及周围采样区的坡向坡度、人为干扰情况等等，照片均为原图，jpg格式，以手机或相机拍摄，采样点的具体经纬度信息在压缩包内的单独Excel表格中，可对照查看。整个采样的红色样方框大小为0.5米*0.5米。

The data file is packaged as a 7z compressed archive, which can be extracted and opened using 7-Zip software. The archive contains two sub-compressed packages, including survey photos of 30 sampling sites in the Sichuan-Tibet region and 30 sampling sites in Guoluo Prefecture, Qinghai Province, collected in 2020. Photos for each sampling site are stored in a dedicated folder named after the site's unique ID number, with the sampling date appended as a suffix to the folder name. The photo set for each site includes landscape photos around the sampling point, photographs of plant communities within the sampling quadrat, and close-up shots of dominant species. These photos enable observation of the vegetation community status within the quadrat, soil surface conditions, aspect and slope of the surrounding sampling area, anthropogenic disturbance conditions, and other relevant field information. All photos are unedited original files in JPEG format, captured using mobile phones or digital cameras. The exact longitude and latitude coordinates of each sampling site are provided in a separate Excel spreadsheet within the compressed archive for cross-reference. The red sampling quadrat used across the entire survey has a dimension of 0.5 meters × 0.5 meters.
