| 摘 要： | 采用样方法对贵州平坝县十字乡自然生长的斑苦竹种群结构特征进行调查分析,结果表明:斑苦竹种群年龄结构中Ⅱ龄级所占比例最大,达到27.9%,其次为Ⅰ龄级和Ⅲ龄级,占调查总数的比例分别为25.1%、20.0%;胸径主要分布在31～45 mm;高度主要分布在6.0～8.9 m,占总体的57.8%。各龄级植株的径级、高度级存在一定差异。随着龄级的增加,胸径变小,说明斑苦竹种群存在衰退的趋势。

| Abstract: | The research was carried out on the population structure characteristics of Pleioblastus maculate grew naturally in Shizi County,Pingba County in Guizhou Province.The results showed: the population had the most Ⅱ-age-class individual plants,the proportion reached 27.9%,then Ⅰ-age-class with 25.1% and Ⅲ with 20.0%.The main distribution range of DBH(diameter at breast height) was 31 ～ 45 mm.The main distribution range of height class was 6.0 ～ 8.9 m with 57.8%.The diameter class and height class had a certain difference among the different aged class.DBH decreased with the age class increasing,which showed that Pleioblastus maculate population had the decreasing tendency. |
