崛围山区水保草种草冠覆盖与根系分布研究
|
摘要
为了解北方土石山区水土保持草种草冠覆盖与根系分布情况,筛选覆盖范围优势草本植物物种用于水土流失防治,通过野外调查和测量,研究了崛围山区9种草本植物草冠覆盖范围与根系分布范围及变化规律。结果显示:9种草本植物根系分布范围与草冠覆盖范围之间符合幂函数关系;从覆盖范围来讲,香根草在9种草本植物中可优先考虑用于植物措施防治水土流失。
In order to understand aboveground coverage and root distribution of the herbaceous plants and to select species with superior coverage areas for soil and water conservation inthe North earth-rocky mountain area, aboveground coverage and root distribution of nine species were studied by in-situ measurement and investigation. The results show that the root distribution area is increased with aboveground coverage area in power function relation for the nine herbaceous species. Vetiveria zizanioides L. is a priority among the nine species for soil and water conservation by vegetation measures based on the results of coverage areas and root distribution.
