摘要
为探究艾丁湖区域地下水资源与旱生植被覆盖度之间的关系,采用流域调研、数据收集、遥感反演、理论分析等方法研究了艾丁湖区域地下水资源变化对旱生植被覆盖度的影响规律。结果表明,植被覆盖度与地下水资源开采量关系密切,人工植被平均覆盖度与地下水开采量的变化趋势具有一致性;天然植被平均覆盖度与地下水开采量在1976~2005年期间的变化趋势呈负相关,而在2005~2017年期间变化趋势一致。生态保护政策和科学治理方略的实施,有利于控制地下水资源的利用量,天然绿洲的面积及天然植被|覆盖度均开始回升,生态环境得到了改善。
In order to explore the relationship between groundwater resources and xerophyte vegetation coverage in Aiding Lake area.methods of basin investigation.data collection.remote sensing inversion and theoretical analysis were used to analyze the impact of groundwater resources change on the coverage of xerophytes.The results show that the veg-etation coverage is closely related to the exploitation of groundwater resources.and the change trend of the average artifi-cial vegetation coverage is consistent with the exploitation of groundwater.The average coverage of natural vegetation has a negative correlation with the change trend of groundwater exploitation in 1976-2005,while the change trend is the same with the groundwater exploitation in 2005-2017.The implementation of ecological protection policies and scientific management strategies is conducive to the control of the utilization of groundwater resources.The area of natural oases and the coverage of natural vegetation have started to rise.and the ecological environment has been improved..
