In this paper,based on using sedimentary profile,i.e.,representative Hole A and combining the age-determination date,we have synthetically studied the various environmental elements of Balikun lake in northern Xjnjiang.Then we have gained the sedimentary environmental signs that fit in with the biological,physical and chemical processes in arid land,which confirmed that the environmental change of Balikun Lake has evolved in the climatic pattern of alternating between cold-wet and warm-dry.In other words,the environmental change in this region acted upon the inland-type climate since the late period of late-pleistocene.Owing to the influence of the special geographic position and inner-outer factors of climatic system,fluctuating intensity,range and period of the inland-type climate have displayed the regional difference in time-space distribution,which constitute the change model of inland-type climate.The result mentioned above provides the new evidence for regional study jn globe change.
