摘　　要：选择典型荒漠河段引洪灌溉生态修复区域,利用遥感数据和地下水监测数据,结合实地调查等手段对和田河沙漠段典型荒漠河岸林引洪灌溉生态修复效果开展了研究,采用多波段水体指数MBWI和归一化差异植被指数NDVI分析评价研究区生态修复效果。结果表明:引洪灌溉对生态修复区地下水有抬升作用,缓解年内地下水持续降低趋势,同时提高植被覆盖水平,这导致植被覆盖度高地区面积增加,无植被覆盖地区面积减少。然而目前引洪灌溉生态修复存在积水面积较大,积水时间较长,区域分布不均等问题,引洪灌溉生态闸位置和合理的运行制度还需要进一步研究。研究成果可以为干旱区内陆河流域荒漠河岸林生态修复提供借鉴。In this paper,the typical desert riparian forest is selected as the ecological restoration area for flood diversion irrigation.Based on the aerial remote sensing technology and the real-time monitoring data of groundwater monitoring wells,combined with field investigation,the ecological restoration effect of typical flood diversion irrigation desert riparian forest in Hotan River desert was studied.Multiband water body index(MBWI)and normalized vegetation index(NDVI)were used to evaluate the ecological restoration effect of water body area and vegetation coverage in the study area.The results show that flood diversion irrigation has a certain role in raising groundwater in the ecological restoration area,alleviating the continuous downward trend of groundwater in the year,improving the level of vegetation coverage,increasing the area of high vegetation coverage,and reducing the area of non-vegetation coverage.However,at present,the ecological restoration of flood diversion irrigation has the problems of large ponding area,long ponding time and uneven regional distribution.The location and reasonable operation system of the ecological gate for flood diversion irrigation need to be further studied.The research results can provide reference for ecological restoration of desert riparian forest in inland river basin of arid region.
