| Abstract: | Based on remote sensing images,we monitor the land type changes in the Aydingkol Lake Basin from 1990 to 2019,and use kinds of indexes and radar chart methods to reveal the urban expansion process and explore its driving mechanism.The results show that:(1)From 1990 to 2019,the land types in the basin changed greatly,and the urban expansion was obvious.(2)Urban expansion has experienced a medium-speed expansion stage and a high-speed expansion stage.(3)The built-up areas of the three main cities in the basin have expanded by about 40 km2,60 km2,and 40 km2 respectively.The three cities have expanded outwards as a whole on the original basis.Natural conditions are the main factor affecting urban development in the arid areas of the west,and urban expansion is gradually being affected by economic and policy factors. |
