摘要
依据野外调查和卫片判译,将那曲地区的草地分为山地草甸、高寒草甸、高山草原、高寒荒漠等5类和37个草地型。对主要草地型的分布规律、生境条件、优势种、伴生种、高度、盖度、产量及载畜量做了描述和计算。高山嵩草、紫花针茅分别是那曲草甸草地和草原草地中最优秀的建群种。藏嵩草草地和华扁穗草草地分别是那曲草甸和草原带上最重要的冬春牧场。
The grassland of Naqu region can be divided into five types and 37 subtypes. The distribution, eco-tope, sward height, cover degree and herbage yield of each subtype is described. Kobresia pygmaea and stipa purpuea is dominant species in alpine meadow and steppe, respectively. K. littelezdalei and Blysmus sinocompre-ssus grassland is the most important grazing land for spring and winter.
