巴什吐格草原草场类型及其资源开发利用

对巴什吐格草地自然地理环境、植被分布规律与草场类型特点研究结果表明，该区草地是中昆仑山北坡自然环境最好、植被发育最好、放牧地形最好和供水条件最好的典型草场之一。自南向北，草场植被垂直分布十分明显，东、西部植被水平分布亦有较显著差异。根据新疆草地分类系统可划分为：山地荒漠、山地草原化荒漠、山地荒漠草原、山地典型草原、高寒草原和高寒草甸６类及６个亚类、１１个组、１４个型。。山地荒漠草原和山地典型草原分别是冬春场和夏秋场的主体类型，各占冬春场和夏秋场草地可利用面积的４８２２％和６６７１％。结合当地草场实际，提出了草地合理开发利用的意见。

RANGELAND AND PASTURELAND TYPES AND THEIR EXPLOITATIV AND UTILIZED SITUATION IN BASHITUGE REGION

Bashituge Region are situated along the northern slopes of Mid-Kunlun mountainous areas.The natural geographical environments,distributive law of local vegetations and characteristics of rangelands were studied,the results indicated that the region is one of the most typical pasturelands.It is quite clear that the vegetations were shown a vertical distributional scene from south to north all around.As for the honizontal distribution,the vegetations on the rangelands in the east direction are more distinctly different from those in the west.According to the classification of rangelands,they are 6 categories, 6 subcategories,11 groups and 14 subgroups.The mountainous desert steppe rangelands and typical mountainous steppe rangelands are divided into winter-spring and summer-autumn pasturelands in similar manner,but the utilizable areas were estimated at 48 22% and 66 71% respectively in percentage from each other.When we discussed by theory from practice about local rangeland conditions,those suggestions for reasanable exploitation and utilization in use for rangelands were suggested in the paper.
