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，包括灌木和草本的根、茎、叶、花、果、实（种子）等植物样本。", "ds_source": "
本数据集为野外调查结合后期整理得到的第一手观测数据。其中植物标本实物通过野外实地采集而获得；标本图像数据是在对实物标本制作完成后对其拍照并电子化而获得；植物分类特征通过查阅中国科学院植物研究所开发的“植物智”软件而获得；地理坐标、生境要素通过现场GPS测定和实地调查而获得。植物实物标本经现场采集、进行挂签，填写野外采集号，并记录采集样点的地址、地理坐标、生境。室内以黄麻纸或报纸进行压制、阴干，带回实验室进行鉴定登记。野外对植物标本进行样本采集号的编写，不同地区和不同的人员由于其习惯的不同，编号采用样点ID+样本号（HM-02-CD-0004-001）或年份+样本号（2018-154）的方式。野外共获得标本3500余份，经筛选、剔除腐烂标本，共获得3332份完整标本。", "ds_process_way": "
