The ecological relationship of species , community and environment in elaeagnus mollis communities were studied by using twinspan and dca 本文应用twinspan分类和dca排序相结合的方法,研究了翅果油树群落的物种、植物群落与环境的生态关系。
Elaeagnus mollis is one of the larger shrubs and dwarf trees , being an endemic to china and one of the china protected two - grade rare and endangered plants 翅果油树( elaeagnusmollis )是一种乔木状灌丛或小乔木,为国家2级珍稀濒危保护植物。
This experiment also studied the transplanting technology of elaeagnus mollis diels tube plantlet and environmental conditions and the transplanting survival ratio was up to 66 % 本实验对翅果油树试管苗的移栽技术及环境条件进行了探讨,移栽成活率达66 。
The community composed of elaeagnus mollis as the constructive species is one of the typical vegetation types in the hills and lower - mountains of southern of shanxi 以翅果油树为建群种形成的群落,是山西南部暖温带落叶阔叶林地带低山丘陵区的代表植被类型之一。
The structural diversity of elaeagnus mollis communities was studied by using both extended shannon - weaver index and stvi ( structure index based on variance ) . the result from the both indices showed similar change tends 采用扩展了的shannon - weaver指数和stvi指数对翅果油树群落进行结构多样性研究,两个指数表现出较一致的变化趋势。
