中文摘要：

通过对赤水市几种主要竹种的生长情况研究,结果表明：楠竹不同年龄的平均杆质量与总质量之间都存在着一定的差异,随年龄的增加有逐渐降低而趋于平缓的趋势,并且平均杆质量与总质量之间表现出一致的变化规律,但叶质量差异不大,这与楠竹的生长特性密切相关;各竹种因人工经营强度的差别以及不同竹种本身特性的差异,不同竹种年龄结构存在一定的差别;除清甜竹、慈竹、吊丝球竹外,其他竹种的株高、胸径、枝下高之间存在着一定的相关性。

英文摘要：

The growth of several kinds of bamboo species of Chishui City were studied.Result shows that： there exist certain differences on the average bamboo quality total quality of Phyllostachy spupescens with different ages,tending to decrease and then stay steady with the increase of age;the average pole mass total mass show the same variation law;however,there is little difference in leaf quality,which is closely related to the growth characteristics of P.spupescens.Due to the different cultivation intensity characteristics of different bamboo species,age structure of different bamboo species have certain differences;the height,DBH under branch height of the other bamboo species have certain correlation except Dendrocalamus sapidus,Neosinocalamus affinis Sinocalamus beecheyanus.
