摘　　要：[目的]探明水住与典型湿地植物生长之间的相互复杂关系，揭示湿地植物依赖水位变化的生长规律。[方法]通过选择不同月份的遥感影像，经解译定量分析不同水位条件下湿地植被带面积及其空间分布规律。[结果]鄱阳湖湿地水文具有显著的月周期特征，不同高程植被带的淹水频率、淹水历时和淹水周期都有明显差异，由此控制着湿地植被分布呈现显著的带状特征。[结论]该研究结果可为鄱阳湖湿地资源保护和利用提供科学依据。[ Objective ] The research aimed to identify the complex relationship between the hydrological and the growth of typical wetland plants, and then reveal the growth regularity of the wetland plants which depend on water level change. [ Method ] Based on the images in differ- ent months by remote sensing interpretation, we analyzed wetland vegetation zone area and its spatial distribution under different water level conditions. [ Result] Poyang Lake wetland hydrology had a remarkable characteristic of monthly period. There were significant differences among flood frequency within different elevation vegetation zone, flooding duration and period, thus controlled the significant band features of wetland vegetation distribution. [ Conclusion ] The research can provide scientific references for the protection and the utilization of wetlands resource in Poyang Lake area.
