西藏草地藏沙蒿资源分布调查
|
摘要
采用多种调查手段对西藏草地蒿属植物(Artemisia)的种类、藏沙蒿(Artemisia wellbyi)的生态分布开展了调查。结果表明,西藏草地有蒿类植物共计57种;藏沙蒿在藏北、藏西北海拔为3581~4691 m的区域分布,其生境多为河滩、草坡、流石滩;分布区域光照充足、紫外线和太阳辐射强度大、空气稀薄、土壤贫瘠、降水量少、气候寒冷;藏沙蒿资源量极具潜在的开发利用价值,可以作为西藏荒漠化区域生态和产业发展资源予以利用。
In the present paper,various approaches were adopted to investigate the species of Artemisia and its ecological distribution in Tibet grassland. Results indicated that there were in total 57 species of Artemisia located at river shoal,grass slope and flow rock shoal at the altitude of 3581-4691 m in the west and north of Tibet. The ecological environment in that area was abundant with sunshine,ultraviolet and high strength solar radiation,rarefied air,barren land,lower precipitation,and cold whether. With its abundance and potential value to be explored and utilized,Artemisia wellbyi could contribute to ecological restoration in dessert region in Tibet and industrial improvement.
