Investigation on oil plant resources in Lushan nature reserve

通过野外调查、标本采集与鉴定和查阅文献,对庐山自然保护区的油脂植物资源进行了统计和分析。结果表明:庐山自然保护区共有油脂植物76科、194属、298种,其中裸子植物8科11属22种、被子植物65科179属271种、单子叶植物3科4属5种,占该区种子植物科属种的比例分别为46.62%、22.45%、14.16%,占全国油脂植物科属种的比例分别为70.37%、48.87%、36.61%;含10种以上油脂植物的优势科有10个,含油量在40%以上的有54种,隶属24科34属。庐山自然保护区油脂植物地理分布类型多样,起源古老,以温带成分占优势。

The oil plant resources in Lushan nature reserve were investigated through field investigation,sample collection, sample identification and literature review. The results showed that 298 species, be-longing to 194 genera and 76 families, were distributed in Lushan nature reserve. There were 22 species,11 genera and 8 families of gymnosperms, 271 species, 179 genera and 65 families of angiosperms, and5 species, 4 genera and 3 families of monocotyledon, taking a ratio of 14.16%, 22.45% and 46.62%in Lushan oil plants respectively, and taking a ratio of 36.61%, 48.87% and 70.37% in Chinese oilplants. The dominant families which had 10 or more oil plant species included 10 families. There were 54species, belonging to 34 genera and 24 families, in which the oil contents were higher than 40%. Lushannature reserve distribution type of the oil plants was various and origin of ancient, and temperate typeswere dominant.
