柴达木盆地天然草地面积696．9万公顷，依据中国草地类型分类系统，可分为温性草原类、高寒草原类、温性荒漠类、高寒荒漠类、低地草甸类、山地草甸类、高寒草甸类及沼泽类等8类、38个草地型。主要由于水分、热量条件的变化，导致柴达木盆地草地类型在东半部以温性草原类为主，西半部以温性荒漠类为主。受地形地貌特征及海拔高度的影响，草地类型垂直分布格局明显，从盆地中心至边缘呈现沼泽类、低地草甸类、山地草甸类、温性荒漠类或温性草原类、高寒草原类、高寒草甸类或高寒荒漠类。
柴達木盆地天然草地麵積696．9萬公頃，依據中國草地類型分類繫統，可分為溫性草原類、高寒草原類、溫性荒漠類、高寒荒漠類、低地草甸類、山地草甸類、高寒草甸類及沼澤類等8類、38箇草地型。主要由于水分、熱量條件的變化，導緻柴達木盆地草地類型在東半部以溫性草原類為主，西半部以溫性荒漠類為主。受地形地貌特徵及海拔高度的影響，草地類型垂直分佈格跼明顯，從盆地中心至邊緣呈現沼澤類、低地草甸類、山地草甸類、溫性荒漠類或溫性草原類、高寒草原類、高寒草甸類或高寒荒漠類。

Rangeland area is 696.9 x 10^4 hm^2 in Chaidamu basin, according to China＇ s rangeland classification system, the rangeland of Caidamu basin can be divided into 8 types： temperate steppe type, alpine steppe, temperate desert, alpine desert, lowland meadow, mountain meadow, alpine meadow and marsh etc., 38 formations. Mainly due to moisture, heat conditions change, the rangeland type in the eastern half of Chaidamu basin is mainly temperate steppe type, and temperate desert mainly in the western half. Because of the effect by terrain features and altitude, clear pattern of vertical distribution of rangeland types from the basin center to the edges is marsh type, lowland meadow, mountain meadow, temperate desert or temperate steppe, alpine steppe, alpine meadow or alpine desert.
