| 摘要 | [Objectives] To analyze the dynamic changes of maximum vegetation coverage in Ili River Basin from 2006 to 2020, and to explore the vegetation change and its influencing factors in the forest-grassland ecotone of Ili region. [Methods] The pixel dichotomy model was used to process the MODIS data and analyze the change of vegetation coverage in the Ili River Basin from 2006 to 2020. [Results] (i) The vegetation coverage in the Ili River Basin increases gradually from west to east, and fluctuates greatly between years. (ii) By monitoring the change rate of the maximum vegetation coverage, it is found that the vegetation coverage of the basin has experienced a process of first decline and then recovery in the past 15 years. (iii) In spatial distribution, vegetation coverage has improved in some regions, while it has deteriorated in others, which may be related to regional climate change and human activities. [Conclusions] The vegetation coverage in the Ili River Basin showed significant spatial and temporal differences during the study period, and its changes were affected by both natural and human factors. |
