It has some main characters following.Lacking seriously of the precipitation brings about the Inner Mongolia s aridness.(1) The barren soil being short of water is the other important cause.

分析得出：内蒙古干旱成因复杂，大致有如下特征：①空中可降水量严重偏少，造成内蒙古中西部地区干旱化的趋势非常明显。

Through comprehensive analysis of various physiological indexes, theinitial conclusion was drawn out: Atriplex canescens cannot survive in the areawithout irrigation and or with scarce rainfall; the limitation scope of rainfall forAtriplex canescenss survival is under research; this species can only be extended inthe area with certain favorable rainfall.

通过对各项生理生态指标的综合分析初步得出如下结论：在没有灌溉和降雨量不大的干旱地区难易生存，至于四翅滨藜在降雨量多少毫米的范围内能够生存，还需要进一步的研究；在干旱沙区进行推广，必须有一定的灌溉条件。

Autoxidation rate increased in the beginning and after 3 days stress it decreased to the level of that before the stress.
