中文摘要：

以长白山自然保护区为研究对象，对不同海拔湿地植物群落结构及其物种多样性进行研究．调查研究发现：长白山北坡湿地有植物37科83属142种，南坡湿地有植物33科71属103种，西坡湿地有植物37科83属132种，其中西坡和南坡的植物科、属相似性较高．通过实地调查记录和重要值的计算，对长自山北坡、南坡、西坡不同海拔湿地植物群落结构名称及其湿地类型进行了判定和划分，并根据3个坡向上不同海拔湿地样方中的植物种数，探讨了长白山湿地植物多样性随海拔梯度变化的趋势．

英文摘要：

This research area is Changbai Mountain Nature Reserve. The result showed that there were 142 species 83 genera 37 families wetland plants in the wetland in the north slope of Changbai Mountain, 103 species 71 genera 33 families in the south, and 132 species 83 genera 37 families in the west. The west slope and the southern slope of the plant families, is a high similarity. And in the field survey and record the important value terms, based on the northern slope of Changbai Mountain, we did the determination and classification of the southern slope, at different altitudes on the western slope of the wetland plant community structure name and kind. According to the number of three different altitudes upward slope wetland plots species investigation and analysis, summed up the diversity of wetland plants in Changbai Mountain with the trend of elevation gradient.
