天山中段乌鲁木齐河河源区，经历多次冰川作用，冰碛物自冰川末端外延12km。其上土壤发育与生物发展同步进行。在光秃的冰碛石表面，首先出现微生物群落和藻类群落，继之生长地衣和苔藓，最后演化为高山和亚高山草甸植被。与植物同步进化的原始土、新成土、寒冻雏形土，（A）-C型在先，A－C型继后，最终发育成A－（B）-C型。这些土壤具有负温和含冰的土体，土壤冻结-融化-冻结，常发生冰-水-冰的相态变化，表土产生冻胀丘、石环、A层呈鳞片状结构，土壤腐殖化程度低，矿物分解弱，粗骨性强。剖面分异状况由弱到强，原始土壤无发育层次，寒冻正常新成土腐殖层明显，草毡寒冻雏形土的A层和B层发育较为完善。
The middle reaches of the Tianshan Mountains, along the Urumqi River and Heyuan area, have experienced several glaciations and the moraines have been extended by 12km from the end of the glacier. Its soil development and biological development simultaneously. On the bare moraine stone surface, microbial communities and algae communities first appear, followed by lichens and moss, which eventually evolve into alpine and sub-alpine meadow vegetation. The original soil, newly formed soil, and frozen embryonic soil evolved in synchronization with the plant, (A) -C type first, A-C type later, and eventually A- (B) -C type. The soil has negative temperature and ice-bearing soil, the soil freezing-thawing-freezing, and the phase change of ice-water-ice often occurs. The frost-heaving mound and stone ring are formed on the topsoil. The A-layer is scale- Low degree of mineral decomposition weak, strong coarse bone. The differentiation status of the sections is from weak to strong, the original soil has no development level, and the normal frozen soil layer is obviously new. The development of layer A and layer B of the frozen soil is more perfect.
