Spatiotemporal Evolution of Oasis Area and its Driving Factors in Jiashi County,Kashgar region
Based on the four remote sensing interpretation results from 1990 to 2020,this paper analyzes the evolution process of oasis area and land use type in Jiashi County from the perspective of temporal and spatial scales by using the study methods of area trend change amplitude,land use/cover change index and transfer matrix,and the main driving factors affecting the oasis pattern in Jiashi County are analyzed starting from factors such as wa-ter resources conditions and human activities.The results show that the year 2000 is the boundary point of Jiashi County,before which the influence of human activities is weak and natural oasis is dominant.After 2000,the influence of human activities increased,artificial oases is dominant.In the fu-ture,the probability of water resources changing from abundant to flat to dry is increasing,and the risk of maintaining the existing oasis pattern is grea-ter.It is suggested to actively adjust the oasis structure to cope with the risk brought by the change of water resources.
