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.

With the IAP Prediction System of Short-term Climate Anomaly, two sets of seasonal and extra-seasonal ensemble hindcasts have been performed during the period of 1980～1994 in order to assess the prediction skill of the IAP PSSCA with two different schemes The difference of the two schemes is in the different version of AGCM used, with the IAP AGCM 1 1 in one scheme and the IAP AGCM 1 2 with an improved surface albedo parameterization in the other Comparisons of the hindcast results with the observations show that IAP PSSCA is capable of predicting the precipitation anomaly to some extent In the eastern China largely affected by Asian monsoon and SST anomalies, the prediction skill is relatively high, especially in the Southeastern China where the anomaly correlation coefficient can reach as high as 0 50 in the severe flood and drought years This may suggest that the possible mechanisms for these severe disasters have been well captured by the IAP PSSCA The prediction skill is higher for the modified model AGCM 1 2 as the model's climatological state is well simulated This indicates that models with reasonable land process will improve the prediction skill for short-term climate prediction

利用中国科学院大气物理研究所研制的短期气候距平数值预测系统，种版本的大气环流模式：AGCM 1.1和AGCM 1.2，分别以2月11～19日的9天大气观测值为初始场，以给定海温为边界场，对1980～1994年的15年的降水异常进行了两组集合后报试验。对试验结果进行定量评估表明：IAP PSSCA对降水异常具有一定的预测能力，特别是在中国东部受东亚季风及海温异常影响的地区，IAP PSSCA具有较高的预报技巧，其中以东南区域(包括江淮流域和华南地区)最高，尤其是对有洪涝灾害的降水异常年，距平相关系数在0.50左右，接近可供业务使用的要求，说明模式能够抓住在东亚季风区存在的某种物理机制，从而提高了这一地区的预报技巧；另外，两个大气环流模式相比，改进了地表反照率的AGCM 1.2的15年集合平均预测技巧略高于AGCM 1.1，特别是在华北地区，预测效果有明显提高，这表明改进地表反照率从而改进了模式的气候平均态的模拟，能提高气候模式的预测能力，说明较好的陆面过程引入模式对短期气候预测是有益的。
