本图集以中国北方农牧交错带的科尔沁沙地、呼伦贝尔沙地和毛乌素沙地为核心，利用大疆精灵系列无人机（DJI phantom 4），对典型的荒漠和固沙植物群落进行垂直向下连续拍摄，最终整合成为约100 m×100 m的植物群落厘米级正射图像，建群种或优势种包括：芨芨草、羊草、狼针草、柠条锦鸡儿、沙蓬、四合木、盐爪爪、榆树、针茅等。", "ds_source": "

This atlas takes the Horqin Sandy Land, Hulunbeier Sandy Land and Maowusu Sandy Land in the farming pastoral ecotone of northern China as the core, and uses the DJI phantom 4 to take vertical and downward continuous photographs of typical desert and sand fixing plant communities, and finally integrates them into about 100 m × A centimeter level orthophoto image of a plant community at a height of 100 meters, with established or dominant species including: Achnatherum splendens, Leymus chinensis, Wolf needle grass, Caragana korshinskii, Sarcandra sargentiana, Tetrandra sinensis, Salt claw, Ulmus pumila, Stipa arundinacea, etc.
