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。

Why do Canadians have to attach to Canadian sovereign values? It is partly because the values are the foundation of our country's establishment, building and development; namely since you have been in Canada, you have to respect and attach to the sovereign values, which are the fundamental principle of respecting national sovereignty, masters and themselves. It is a hinderance to yourself if breaking the principle. For example, if you live in or come to a nice environment, you can enjoy it as long as you take care of and cherish it; or, you will suffer from it when the nice environment turn into a bad one.

为什么要归属加拿大至高无上的价值观，一是，加拿大至高无上的价值观是本国的立国、建国和国家发展之本；也就是，既然在或来到加拿大，就得尊重和归属于至高无上的价值观，这是尊重国家主权、尊重主人、尊重自己的基本原理，如果违背原理去做人做事是无利的，例如，既然生存在或来到一个好的环境中，就要爱护和珍惜它，才会享用到好环境；否则，就会将好环境变成坏环境而得受累。
