色林错湖区植物科、属、种统计数据集（2012-2013）

青藏高原研究所寒区地表水文学过程课题组经过3年的努力，完成色林错环湖区域的植物考察、采样与鉴定工作，共采集植物模式标本200余份，拍摄高清植物图片2000余张。目前，科研人员已鉴定出植物种类45种，分属于23科35属。该成果邀请中科院植物研究所植物分类专家对已鉴定的所有植物种名进行二次核实和校正，将色林错环湖区域的植物资源匹配相应的图解和注解说明，进行专业的排版、编校并出版成册，已出版书籍：宋洪涛，高海峰，等著. 2017. 色林错植物图鉴: 羌塘"鬼湖"的植物生灵. 北京：科学出版社. 可供该区域相关学术研究时参考之用。
色林错湖区属半干旱草原地带，罕见乔木和灌木分布，且草本植物种类也相对稀少。但植被对维持当地自然生态的完整性、野生动物栖息地及牧民生产生活起着不可或缺的作用。调查结果表明，环湖区域内植物种呈现科数多但同科物种属、种少的状况，其中：菊科物种最多，隶属7属8种，分别为火绒草属1种，蒿属2种，亚菊属1种，风毛菊属1种，狗娃花属1种，蒲公英属1种和香青属1种；其次为紫草科，共4种，均为微孔草属；毛茛科3属3种，分别为碱毛茛属1种，翠雀属1种，唐松草属1种；玄参科2属3种，分别为兔耳草属1种，马先蒿属2种；景天科3种，均为景天属；唇形科2种，均为青兰属；莎草科2种，分别为嵩草属1种，薹草属1种；蓼科2种，均为蓼属；石竹科2种，分别为无心菜属1种，蝇子草属1种；禾本科2种，分别为早熟禾属1种，披碱草属1种；百合科2种，均为葱属。此外，科内单属单种的植物12种，分别为瑞香科狼毒属、荨麻科荨麻属、龙胆科龙胆属、川续断科刺续断属、十字花科念珠芥属、蔷薇科委陵菜属、柽柳科水柏枝属、报春花科点地梅属、豆科黄芪属、蝶形花科棘豆属、藜科藜属和紫葳科角蒿属。

Over three years of dedicated work, the Research Group on Cold Region Surface Water Hydrological Processes from the Institute of Tibetan Plateau Research completed plant surveys, sampling and identification tasks in the circum-lake area of Siling Co. A total of over 200 plant type specimens and more than 2,000 high-resolution plant images were collected. To date, researchers have identified 45 plant species belonging to 35 genera across 23 families. For this achievement, plant taxonomy experts from the Institute of Botany, Chinese Academy of Sciences were invited to conduct secondary verification and correction of the scientific names of all identified plant species. The plant resources in the circum-lake area of Siling Co. were matched with corresponding illustrations and explanatory notes, followed by professional typesetting, editing, proofreading and publication. The published book is: Song Hongtao, Gao Haifeng, et al. 2017. *Siling Co Flora: Plant Lives of the "Ghost Lake" in Qiangtang*. Beijing: Science Press. This work can serve as a reference for relevant academic research in this region.

The Siling Co lake region belongs to the semi-arid steppe zone, with rare occurrence of trees and shrubs, and relatively scarce herbaceous plant species. Nevertheless, vegetation plays an indispensable role in maintaining the integrity of local natural ecosystems, wildlife habitats and the production and livelihood of local herdsmen. The survey results indicate that the plant species in the circum-lake area are characterized by a large number of families but few genera and species within each family. Among them: Asteraceae has the most species, with 8 species across 7 genera, namely 1 species of *Leontopodium*, 2 species of *Artemisia*, 1 species of *Ajania*, 1 species of *Saussurea*, 1 species of *Heteropappus*, 1 species of *Taraxacum* and 1 species of *Anaphalis*; followed by Boraginaceae, with 4 species all belonging to *Microula*; Ranunculaceae has 3 genera and 3 species, namely 1 species of *Halerpestes*, 1 species of *Delphinium* and 1 species of *Thalictrum*; Scrophulariaceae has 2 genera and 3 species, namely 1 species of *Lagotis* and 2 species of *Pedicularis*; Crassulaceae has 3 species all belonging to *Sedum*; Lamiaceae has 2 species all belonging to *Dracocephalum*; Cyperaceae has 2 species, namely 1 species of *Kobresia* and 1 species of *Carex*; Polygonaceae has 2 species all belonging to *Polygonum*; Caryophyllaceae has 2 species, namely 1 species of *Arenaria* and 1 species of *Silene*; Poaceae has 2 species, namely 1 species of *Poa* and 1 species of *Elymus*; Liliaceae has 2 species all belonging to *Allium*. In addition, there are 12 plant species belonging to monotypic genera within their respective families, including those from *Stellera* (Thymelaeaceae), *Urtica* (Urticaceae), *Gentiana* (Gentianaceae), *Morina* (Dipsacaceae), *Torularia* (Brassicaceae), *Potentilla* (Rosaceae), *Myricaria* (Tamaricaceae), *Androsace* (Primulaceae), *Astragalus* (Fabaceae), *Oxytropis* (Papilionaceae), *Chenopodium* (Chenopodiaceae) and *Incarvillea* (Bignoniaceae).
