本数据集针对阿拉善高原-河西走廊荒漠区干旱气候特点，以我国河西走廊和阿拉善高原为调查核心区，兼顾毗邻马鬃山、祁连山西部山地、甘肃中部干旱区等区域，于2017-2021年，调查了分布在这些区域的灌木荒漠、半灌木-矮半灌木荒漠、矮半乔木荒漠、多汁盐生矮半灌木荒漠、一年生草本荒漠等植被类型。调查的主要植被群系包括：梭梭荒漠、霸王荒漠、盐爪爪荒漠、短舌菊荒漠、猪毛菜荒漠、红砂荒漠、白刺荒漠、柽柳荒漠等。\n
\n调查区域分为两个主要片区，其中，阿拉善高原280个调查点、河西走廊荒漠区184个调查点位。本数据集包含有调查现场照片、无人机照片及土壤剖面照片三部分。以调查区内所有荒漠植物群落为对象，采用数码相机对植物群落水平分布和生境特征以及灌木和草本样方进行拍摄，获得生境照片3463张，土壤剖面照片453张。同时，为客观反映该区荒漠植物群落的垂直结构，采用无人机分别在距离地面10 m、30 m、50 m、70 m、90 m米和 110 m的高度对群落进行垂直拍摄，以便于划分植物群落界限和研究植物种群空间分布格局特征。除军事管控区禁飞区外，共获得无人机照片2361幅。

It also takes into account the adjacent areas of Mazong Mountain, the western part of Qilian Mountains, and the central arid area of Gansu. From 2017 to 2021, the shrub desert, semi shrub short semi shrub desert, short semi tree desert, and juicy halophytic short semi shrub desert distributed in these areas were investigated Annual herbaceous desert and other vegetation types. The main vegetation formations surveyed include: Haloxylon ammodendron desert, Bawang desert, Salt Claw claw desert, Short tongued Chrysanthemum desert, Salsola deserts, Red sand desert, White thorn desert, Tamarix desert, etc.\n
\nThe survey area is divided into two main areas, including 280 survey points on the Alxa Plateau and 184 survey points in the desert area of the Hexi Corridor. This dataset includes three parts: survey site photos, drone photos, and soil profile photos. Taking all desert plant communities in the survey area as the object, digital cameras were used to capture the horizontal distribution and habitat characteristics of plant communities, as well as shrubs and herbaceous samples. 3463 habitat photos and 453 soil profile photos were obtained. At the same time, in order to objectively reflect the vertical structure of the desert plant community in the area, unmanned aerial vehicles were used to vertically photograph the community at heights of 10 m, 30 m, 50 m, 70 m, 90 m, and 110 m above the ground, in order to facilitate the division of plant community boundaries and the study of spatial distribution characteristics of plant populations. Except for the military control zone and no fly zone, a total of 2361 drone photos were obtained.
