摘要
对河南桐柏山香果树资源分布与群落特征进行了调查研究,结果表明,香果树在河南桐柏山沟谷地带分布广泛,总面积达660hm2以上,总株数10万～20万株.香果树群落属于不成熟的次生群落,其物种丰富度、多样性、均匀度都较低,优势度较高.该香果树种群具有衰退趋势,应加以人为干预和保护.
We researched the resources distribution and community frame of Emmenopterys henry Oliv. of Tongbai mountain in Henan province. The results showed that Emmenopterys henry Oliv. is distributing abroad in valley regions of Tongbai mountain,the total areas are more than 660 hm2,the total trunks are about 1～2 million. Emmenopterys henry Oliv. belongs to immature hypo-community,the abundance,the diversity and the uniformity of species are all lowness,there are obvious superiority. This genus of Emmenopterys henry Oliv. is now in a trend of decay,it should be protected immediately.
