内容摘要

Pass the method on-site research, Data investigation, contrast gathers etc., we h ad investigate t he e cosystem e nvironment c haracteristics, the distributive regularity of natural vegetation, the main problem of the frigid grassland and desert grassland for Qilian Mts. And analyze in earnest to it. puts forward some corresponding solutions.The frigid grassland is distributed over the high sea lever and low heat environment. The vegetation over the zone is short and the categories of the plants almost belong to the same type with similar features, which can be classified into cold zoological ones. Those features make it feasible to better and make use of the plant sources in this region. This essay believes that application for the plant on the zone is certain to create great production and economic value. Concerning such questions as the lowdown of the grass quality, overloading and comparatively lacking of grass esp. in winter seasons. The essay puts forward some corresponding solutions.On the basis of natural condition in Qilian Mts., the distributive regularity of natural vegetation, the productive characteristics of desert grassland and the main problem in animal husbandry were importantly expounded. The main measure to protection, reasonable utlization and focally construction of grassland as well as developing animal husbandry were suggested.
