摘　　要：郑州黄河湿地省级自然保护区在保护生物多样性、维护生态平衡和促进可持续发展方面发挥着重要的作用,其内部河道的变迁会影响保护区内生态环境的稳定性。本研究以湿地生态保护和修复为出发点,基于Landsat卫星影像数据,对研究区内河道变化进行动态监测。通过研究2001—2020年湿地内河道历年来的动态变化,重点探究了其时空分布特征及演变规律。同时,根据河道的变迁划定出易变动区域,分析了自然保护区生态环境动态变化的原因。研究发现:①研究区域内河流面积扩大,河道走向变化较小;②2001—2020年,黄河河道的部分河段面积总量发生波动,河流主体南北偏移范围为0.8~5.3km;③易变动区域主要集中在河道东部及中部区域。本研究可为郑州黄河湿地省级自然保护区的生态分区管控提供有效依据,有利于该区域实施科学、可行的保护措施。Zhengzhou Yellow River Wetland Provincial Nature Reserve plays an important role in protecting biodiversity,maintaining ecological balance and promoting sustainable development.Its internal channel changes can affect the stability of the ecosystem in the reserve.Taking wetland ecological protection and restoration as the starting point,dynamic monitoring of river channel changes in the study area was conducted based on Landsat satellite image data.By examining the dynamic changes of the river channel in the wetland from 2001 to 2020,this study mainly explored the characteristics of its spatial and temporal distribution and its evolution pattern.Also,variable areas were divided according to the changes in the river channel,and the reasons for the dynamic changes of the ecological environment in the nature reserve were analyzed.The research found that the river area in the study area expanded,and the change of the river course was slight.From 2001 to 2020,the area of some sections of the Yellow River channel fluctuated,and the north-south deviation of the main body of the river was in the range of 0.8~5.3km.The variable areas were mainly in the eastern and central part of the river channel.This study could provide an effective foundation for the ecological zoning control of Zhengzhou Yellow River Wetland Provincial Nature Reserve,which would facilitate the implementation of scientific and feasible protection measures in the area.
