摘　　要：河岸带是森林小流域单元的重要组成部分之一 .由于河水的影响和边缘效应等因素的综合作用 ,河岸带植物群落与远离河岸带的森林群落在组成、结构和分布格局等方面存在较大差异 ,其群落最小面积也不同 .本文对长白山原始阔叶红松林河岸带植物群落最小面积和物种丰富度进行了探讨 .结果表明 ,河岸带植物群落的最小面积均小于远离河岸带的森林群落的最小面积 .在河岸带 ,阔叶红松林群落的 6 0、80和 90 %植物种类时的平均最小面积分别约为 80、180和 32 0m2 ;而远离河岸带的森林内部 ,相应的平均最小面积分别为 2 6 0、380和 480m2 左右 .Riparian zone is an important component of small forested watershed. Due to the integrate effects of stream water and edge effect, there are obvious difference in composition, structure, and distribution pattern between riparian community and non-riparian community. Community minimum sampling areas are also different. In this study, minimum sampling areas of riparian community in original broad-leaved and Korean pine forest in Changbai Mountain were studied by using species-area curve. At the same time, species richness of riparian community was discussed. The results showed that the minimum sampling areas of riparian plant community were smaller than those of the non-riparian community. According to the original broad-leaved and Korean pine forest in Changbai Mountain, the average community minimum sampling areas in riparian zone of three plots including 60%,80%,and 90% of community species were about 80 m 2,180 m 2, and 320 m 2, respectively. And then, those of forest community were about 260 m 2, 380 m 2, and 480 m 2 correspondingly. The results also showed that the species richness of riparian community was higher than that of non-riparian community.
