摘要
敬信湿地位于中、俄、朝3国交界处的敬信平原,内江河贯穿,湖泡连片,水域沼泽8 000余hm^2,为多种湿地类型共存的湿地复合体。植被是湿地生态系统的重要组成部分,为了解敬信湿地的植物物种多样性,对该地区以常用的样线法进行了植物物种调查和分析。结果表明:敬信湿地分布有42科,90属,126种,3个变种,1个变型;禾本科和莎草科植物为主的草本植物为优势植物类群,水陆交界处多分布为菊科和豆科植物。
Jingxin wetland in Jingxin plain located at the junction of three countrie North Korea, is a comprehensive wetland covered over 8 000 hectares in extent with s, China, Russia and plentiful rivers, lakes and marshland. Vegetation is a crucial part of ecosystem of wetland. For understanding plant species diversity, the investigation and analysis of the distribution and structure of Flora at this area were conducted by the line-transect method. The results showed that 42 families, 90 genera, 126 species, 3 varieties and 1 forms of variation existed at Jingxin wetland. Herbaceous plants including Gramineae and Cyperaceae distributed as dominant vegetation group. Compostae and Leguminosae plants flourished as main families at the joint of water land.
