四川巴塘海子山高寒灌丛群落的基本特征

Species composition and structure characteristics of alpine shrubland communities of Haizi Mountain in Batang,Sichuan,China

高寒灌丛作为高寒地区的地带性植被广泛分布于青藏高原,在区域生态系统中具有保持水土、涵养水源及生物多样性保护等生态功能。该研究采用统一规范的方法设置了58个样方,对巴塘海子山主要高寒灌丛群落的物种组成、数量特征、生境信息等进行调查。基于最新的中国植被分类系统修订方案,该地区高寒灌丛可划分为3个植被型、11个群系、21个群丛。该研究对每个群丛的特征进行了描述,提供了所有样方的原始数据。

Alpine shrublands,as a zonal vegetation,are widely distributed on the Qingzang Plateau,and play ecological functions such as soil and water conservation,conservation of water resources,and biodiversity protection in the regional ecosystem.This study used a unified and standardized method to set up 58 quadrats to investigate the species composition,quantitative characteristics and habitat information of the main alpine shrublands of the Haizi Mountain in Batang,China.Based on “Vegegraphy of China” compilation and research standards,the alpine shrublands in this area can be divided into three vegetation types,11 alliances,and 21 associations.This paper presents descriptions on the characteristics for each association and provides the original data from all survey plots.
