中文摘要	荒漠河岸带植被在维护极端干旱区生态稳定起着极其重要的作用,研究干旱区荒漠河岸带植被对生态输水的响应及其变化过程,对生态保育恢复及输水政策制定具有重要意义。本文以塔里木河下游流域内的荒漠河岸带植被为研究对象,利用Landsat 8 OLI、Sentinel-2A等数据构建植被覆被数据与典型监测断面植被指数时序数据,分析20132018年荒漠河岸带植被时空变化特征,并结合地下水位数据分析荒漠河岸带植被对生态输水的响应。结果表明:20132018年间,塔里木河下游植被面积呈持续的增加趋势,其中灌木面积恢复最大。胡杨和草本距离河岸较近,沿河岸带植被恢复的区域分布位于距离河道1.0 km和2.5 km的范围,而灌木林恢复区域在双通道输水措施和地下水上升的影响下,沿河岸11 km范围内的灌木均呈现不同程度增加。通过对不同生态断面的3种主要植被的长势分析表明,当地下水埋深大于-5.75 m时,塔里木河下游植被出现明显改善。
英文摘要	Desert riparian vegetation plays a significant role in maintaining ecological stability in extremely arid regions.Understanding the response of desert riparian vegetation to ecological water transport in the arid areas and its changing process is crucial for the formulation of ecological conservation and restoration and water transport policy development.The desert riparian vegetation in the lower reaches of the Tarim River was selected as the research objective.We used multi-source data,including Landsat8 OLI and Sentinel-2A,to construct the vegetation cover data and typical monitoring section vegetation index time-series data.Besides,the temporal and spatial variation characteristics of vegetation in the desert riparian zone from 2013 to 2018 were analyzed.Combined with groundwater level data,we analyzed the response of desert riparian vegetation and ecological water transfer projects.The results showed that the different types of vegetation presented different spatial and temporal changing characteristics after the ecological water transport.The area and spatial distribution of new shrubs were significantly higher than those of other vegetation types.The new Populus euphratica is mainly distributed within 0-1 km and 4.5-6 km of the river channel,and the new shrubs are mainly distributed within 1-4 km of the river channel.The new herbal plants are mainly distributed within 2.5 km of the river channel.Different types of vegetation are affected by ecological water transport modes and monitoring section spaces.The influence of location shows different responses to ecological water transport.At the same time,groundwater levels downstream of the Tarim River is generally uplifted,and vegetation growth is generally improved with the development of ecological water transfer projects.
