摘要
翅果油树(Elaeagnus mollis)是国家二级保护植物,为我国特有种,在山西南部低山、丘陵区分布较多,常形成以翅果油树为主的灌丛植被。本文对翅果油树灌丛的生态地理分布、区系组成、群落外貌、结构等特征进行了研究。结果表明山西翅果油树灌丛保存较好,结构典型、类型多样,是我国特有珍贵群落之一,应进一步加强保护。
Elaeagnus mollis is in the second grade protection in China. It is endemic to China. E. mollis scrub in lower mountain and loess-hill areas of southwest Shanxi province develop perfectly under a special ecological environment. The geographical elements, dominated by temperatical ones, are complex. The community possesses the physiognomy and structure of the warm-temperate deciduous broad-leaved shrubland. Analysis shows that E. mollis scrub in the preserve are a wellpreserved and precious communities with various typical structural
types. According to the integration of importance value and other characteristics of shrub layer and herb layer, this paper has described 8 associations. At the end of this paper, the authors also proposed same proposals ways exploit, utilize and protect the E. mollis scrub.
