Study on DBH-structure of Populus euphratica and Their Spatial Distribution in the Lower Reaches of the Tarim River
胸径结构 胡杨 塔里木河 林木分布
2009/11/18
采用“面”上宏观调查与“点”上典型研究相结合, 集中对塔里木河下游阿拉干断面100 hm2的胡杨(Populus euphratica)林木分布与胸径结构进行了调查。结果发现, 在距河道0-20 m的范围内, 胸径为0-4 cm的幼龄胡杨占最多, 达到13.24%。以后随着离河道距离的增加, 幼龄胡杨所占比例逐渐减小。胸径分布范围简单, 胸径为16-36 cm的林木株数在胡杨林中所占的比例最多。另...
