半固定沙丘 meaning in Chinese
semi-fixed dune
semi-immobile dune
Examples
- Plants growing in the semi - fixed sand dunes , on the other hand , were less branchy with a larger number of first - year shoots which were longer , and grew faster ; their leaves were longer and wider with a low length / width ratio . the characteristics of the branching system and leaf dimensions of the plants in fixed sand dunes were rather intermediary between those of the above . the frequency distribution and their frequency in the herb layer the scrubs also varied with habitats
丘间低地的黄柳灌丛当年枝平均长度增加缓慢,短枝条的比例较高,当年枝枝长频度分布峰值偏左,叶片短而狭,长宽比大;与之相比,分布于半固定沙丘的灌丛当年枝平均长度增加较快,长枝条比例较高,叶片长而宽,长宽比小;固定沙丘上的上述特征大致介于二者之间。 - Root distribution and canopy structure parameters of s . godejevii in different sandy land habitats ( semi - fixed sand dunes , fixed sand dunes and inter - dunes low land ) , as well as species composition and their frequency in the herb layer of the scrubs , were compared the results were as follows : the population hi the semi - fixed sand dunes had the most developed root systems , followed by he population in the fixed sand dunes , and that hi the inter - dunes low land was the last
为了更有效地利用这一重要植物资源,本文对分布于浑善达克沙地三种不同沙地生境(半固定沙丘、固定沙丘、丘间低地)黄柳灌丛的根系分布,冠层特征进行了研究,同时测定了灌丛下草本层植物种类组成及频度,结果表明:半固定沙丘上的黄柳根系最发达(根系分布深,数量大) ,固定沙丘的黄柳明显不及前者,而丘间低地的黄柳根系最不发达。
