摘　　要：应用ＧｒｅｉｇＳｍｉｔｈ邻接格子取样法，研究了我国珍稀植物永瓣藤（ＭｏｎｉｍｏｐｅｔａｌｕｍｃｈｉｎｅｎｓｅＲｅｈｄ．）的地理分布和种群空间格局及其形成机制；分析了其克隆生长格局和生态适应对策．研究结果表明，永瓣藤的分布区域狭窄，其种群空间格局为集群型，克隆生长格局为游击式稀疏线形样式。The geographical distribution and population spatial pattern of Monimopetalum chinense of rare and endemic species in China and its forming mechanisms are studied in this paper, with the method of contiguous grid quadrats of Greig Smith. In addition, the clonal growth pattern and ecological adaptation strategies of M.chinense population are analysed. The results of investigation indicate that the distribution area is very narrow, the population is the colonial spatial pattern, and the pattern of colonial growth is a guerilla line style, which are closely related to the biological characteristics of M.chinense and its population strategies of ecological adaptation.
