青藏高原珍稀濒危植物分布图（2019-2023）

本图集包含了青藏高原荒漠区三种珍稀濒危植物（裸果木、沙拐枣和梭梭）的分布范围，青藏高原荒漠区珍稀濒危植物分布图是基于2019-2023年实地调查的基础上制作而成。通过在实地调查数据集中出现的荒漠植物与中国珍稀濒危植物名录进行比对，提取调查结果中存在裸果木、沙拐枣和梭梭这三种珍稀濒危植物的样点，结合青藏高原荒漠植物群落分别图集，筛选珍稀濒危植物存在的斑块，拼接后绘制成青藏高原荒漠地区珍稀濒危植物分布图。青藏高原地理位置特殊，被誉为“世界屋脊”和“第三极”，是亚洲内陆的一个巨大高原，位于中国的西南部，它南起喜马拉雅山脉南缘，北至昆仑山、阿尔金山脉和祁连山北缘，西至帕米尔高原和喀喇昆仑山脉，东及东北部与秦岭山脉西段和黄土高原相接，对该地区进行珍稀濒危植物分布调查和制图具有重要意义。然而，调查结果显示，青藏高原荒漠区仅有3种珍稀濒危植物，说明青藏高原荒漠植物目前所受环境压力较小。

This atlas contains the distribution ranges of three rare and endangered plant species (Gymnocarpos przewalskii, Calligonum mongolicum, and Haloxylon ammodendron) in the desert region of the Qinghai-Tibet Plateau. The distribution map of rare and endangered plants in the desert area of the Qinghai-Tibet Plateau was compiled based on field surveys conducted from 2019 to 2023. By comparing the desert plant species recorded in the field survey dataset with China's List of Rare and Endangered Plants, sample plots where the three target rare and endangered plant species were detected were extracted. Combined with the atlas of desert plant communities in the Qinghai-Tibet Plateau, patches hosting these rare and endangered plants were screened, and the final distribution map was generated via mosaic mapping. The Qinghai-Tibet Plateau, renowned as the "Roof of the World" and the "Third Pole", is a massive inland plateau in Asia situated in southwest China. It stretches from the southern foothills of the Himalayas in the south to the northern edges of the Kunlun, Altyn Tagh and Qilian Mountains in the north, borders the Pamir Plateau and Karakoram Range in the west, and connects with the western section of the Qinling Mountains and the Loess Plateau in the east and northeast. Conducting distribution surveys and mapping of rare and endangered plants in this region holds significant academic and practical value. However, the survey results indicate that only 3 species of rare and endangered plants exist in the desert region of the Qinghai-Tibet Plateau, suggesting that desert plants in this area currently face relatively low environmental stress.
