The most serious desertification occurred in southeast of MuSu Desert,then appeared inferior degree in midst,north,south and east,anddegression degree in other directions.6.The changes of environment in Mu Su Desert in historical times havebeen controlled by climatic changes in temperature and drought-wetwithin hundreds or thousands years.At present,it came into being suchspatial structure and environmental characteristics fordesertification land because of being relative to other naturalgeographic characters and human activities.In all that,physiognomyand hiemal wind are the driving factors.The sandy matter in stratumis the physical fountain factor.The depravation of surface water inthis region is one of representations of environmental changes, meanwhile,it is also the factor which leads to the degradation ofvegetation and desertification.On the whole,human activity has actedupon these natural elements,becoming a dominant factor in the regionalenvironment changes since Ming and Qing dynasty.7.Influencing of human activities on the environment of Mu Su Deserthad occurred before Qin dynasty,and its intensity of earlier influencewas so slight that it could not cause a large scope and long timeenvironmental changes.
沙漠化的程度是东南部最强,中北部、南部和东部次之,而后向其他方向递减。6、毛乌素沙地历史时期的环境变化是受百年乃至千年尺度的气候冷暖、干湿变化控制的,之所以形成目前这样的沙漠化土地空间分布格局和环境特征,则与其地的自然地理特征和人类活动有密切关系,其中地貌及冬季风是动力因素;地层中的沙物质是物源因素;地表水环境恶化是区域环境变化的表现之一,同时又是植被退化和沙漠化的引致因素;人类活动总体上是叠加在自然因素之上的,只是明清以来在局地环境变化中成为主导因素。7、毛乌素沙地人类活动的环境影响在先秦时期就已出现,早期的影响程度是轻微的,不足以造成大范围、长时段的环境变化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
