康藏高原的气候受着地势的影响,一般甚为寒冷,但在河谷地区稍有不同,尤以较大河流所经之平壩(小盆地),如:雅鲁藏布江流域、拉萨河、澜沧江、雅砻江等河谷地区,由于气候较暖,农作物生长颇佳,形成高原上主要的农业区;其余山岳地带,气候严寒,除牧草能生长外,其他农作物皆不生长,形成高原上的牧区;此外,尚有一些地带适于半农半牧,形成所谓半农牧区。
The climate of the Tibetan Plateau is affected by the terrain. It is generally very cold, but slightly different in the valleys, especially the Pingba (small basins) where the larger rivers pass, such as the Brahmaputra, Lhasa, Lancang, Due to the warmer climates, the crops grow well and form the main agricultural areas on the plateau. In other mountain areas, the climate is cold and no other crops grow except pasture and form the pastoral areas on the plateau. In addition, There are still some areas suitable for semi-farming and semi-grazing, forming the so-called semi-agricultural and pastoral areas.
