【Abstract】 Surrounded by the llarkol Mountains, Karlik Mountains and Qoltag Mountains, Hami Basin is a large intermontane basin in the eastern part of the Tianshan Mountains. Its Geomorphologic outline is influenced by both of the regional geotectonics and cllmatical factors.From high mountain to the interior of the basin, seven types can be classified according to the classificational principles of formation cause of patterns. They are high mountain zone denuded by palaeoglaciers, ice and snow , and weathering of periglacial climate; midmountain zone eroded by surface runoff and denuded by semidryness and dryness; lowmountain and hill zone denuded by dryness; alluvial-pluvial deposition zone at piedmont; plain zone denuded by dryness and deflation in the basin; and dune zone deposited on the plain. The elevation of the most mountainous regions is between 3 000 and 4 000 m, and the highest peak of the Karlik Mountairls is 4 888 m a. s. l. It is 200-800 m a. s. l. in the basin, and the Sar Lake, the lowest place here only 53 m. The difference of elevation between the highest peak and lowest place is up to 4 835 m within 180 km in a hoirozontal distance. Such a great difference of elevation determines a vertical distribution pattern of natural resource zones. In order to use the natural resources rationally and control the natural disasters effectively, it is considered that the forests, grasslands, and wild animals should be protected, and the lumbering should be limited. At the areas of piedmont, flash floods and debris flows occur friquently. They of ten threaten the safety of railways, highways, and farmiand. Therefore,some flood and debris flow works should be constructed. The disaster of blowing sand on agricult ure and transportation is serious at the interior regions of the basin due to the limited precipitation and sparse vegetation. To Plant trees, bushes and grasses at the margional areas between oases and deserts is considered a basic and effective way for reducing the disaster of blowing sand, improving the ecological environment, and strengthening the productivity.更多还原
