| 摘 要： | 对乌兰布和沙漠优良固沙先锋树种花棒(H edysarum scop arium)的克隆生长构型进行了研究。结果表明,花棒具有独特的克隆生长构型,由枝条遇沙埋形成长间隔物的典型的游击型克隆生长构型和由根条形成的典型的密集型克隆生长构型。且固定沙丘的花棒分株种群比半固定沙丘具有较大的密度、较小的平均株距及相似的分株高度。

| Abstract: | Clonal architecture of Hedysarum scoparium,a pioneer plant species for sand fixation were investigated in Wulanbuhe desert.The results showed that H.scoparium had its unique patterns of clone growth :guerrilla pattern,which was made up of long drop due to sand covering phalanx pattern,which composed of roots.Compared with the ramet population in the semi-fixed dunes,the ramet population in the fixed dunes exhibited higher ramet density,smaller average ramet spacing and similar ramet height. |
