| 摘 要： | 在黑龙江省东部林区的老爷岭生态站、凉水自然保护区和绥阳林业局。选取原始林、次生林、人工林等２１个受到不同程度干扰的林型。分春、夏、秋三季进行森林植物物种多样性的调查研究。利用丰富度指数、多样性指数和均匀性指数。从时间和空间上沿干扰梯度对森林群落进行了分析。结果表明，受到适度干扰的次生林生物多样性值最高。多样性值也随季节发生变化。草本植物的多样性值一般高于乔木和灌木物种，草本层多样性值也比较高。

| Abstract: | Investigations about forest plant biological diversity were conducted in 24 forest communities including original forests. secondary forests and artificial forests in Laoyeling Ecological Experimental Station. Liangshui Nature Reserve and Suiyang Forestry Bureau, eastern Heilongjiang forest areas. Field works were completed in spring. summer and autumn. Indices of richness. diversity and evenness were applied in data process on time. space and disturbance gradients. Results showed that forest plant biodiversity is affected by disturbance on its community. The highest values were found in secondary forests. Herb species and herb strata have higher values, and biodiversity values also vary with seasons. |
