青海东部红毛五加生长林区的植物群落特性研究

Community characteristics of Acanthopanax giraldii in the forest of the east Qinghai

为了解青海东部地区红毛五加生长状况以及其在群落中的地位与适应性,采用每木检尺调查方法,对青海东部红毛五加生长林区的植物群落进行研究。结果表明:青海红毛五加生长群落可分为:阔叶林五加群落、灌木林五加群落、针阔混交林、针叶纯林4种类型;红毛五加在植物群落中较为脆弱,红毛五加资源急需保护;红毛五加对乔、灌、草各层片生物均没有依赖性。说明红毛五加可能具备建立单一种群栽培地的生物学特性。

In order to understand the growth status, position and adaptability of the Acanthopanax giraldii Herms. in the forest community in east Qinghai, we investigated the community characteristics of the forests with conventional method of the wooden forest survey. The Acanthopanax giraldii Herms. in Qinghai can be divided into four types： broad leave forest population, shrub population, mixed coniferous population and coniferous population. Acanthopanax giraldii Herms. is vulnerable in communities and in urgent need of protection. Population of Acanthopanax giraldii Herms. has no dependence on all the synusia of trees, shrubs and grasses, which shows that Acanthopanax giraldii Herms. may have the biological characteristics to establish single populations on cultivated land.
