准噶尔盆地北部除了乌伦古河为常年地表径流、沿河两岸有较发育的植被外,其他全为荒漠区。这一地区地貌上有两个突出的特点:一是荒漠的顶面多呈现高低不同的几个平坦台面,表明这里在最近第四纪时期中曾经历过数次抬升与切割剥蚀;二是荒漠区内散布着众多大小极度悬殊、深浅各不相同的封闭型洼地。 In addition to the Wulungu River in the northern part of the Junggar Basin, there are perennial surface runoff and more developed vegetation along both sides of the river, while the rest are all desert areas. There are two prominent features of the landscape in this area: First, there are several flat tops on the top of the desert with different heights, indicating that there have been several uplifts and cutting denudations here in the most recent Quaternary period; second, deserts The area is spread with many extreme disparities in size and depth of different closed-type depressions.
