【摘要】 通过对比研究的方法,考察了东北林业大学帽儿山、凉水实验林场小面积(1～5 hm~2)红松人工林和落叶松人工林与毗邻的天然林间生物多样性的差异。结果表明人工林内植物科、种多样性和丰富度与毗邻的天然林没有显著差异;人工林内昆虫群落、植食性昆虫和蜘蛛功能群物种多样性与毗邻的天然林无显著差异,而捕食性昆虫和寄生性昆虫功能群物种多样性与之有显著差异,人工林内捕食性昆虫物种多样性明显低于天然林,寄生性昆虫物种多样性却明显高于天然林。更多还原

【Abstract】 Using comparative method,the difference of biodiversity between plantations and adjacent natural forests is studied in Liangshui and Maoershan experiment forest farms of Northeast Forestry University.The results are as follows:the difference of plant family and species diversity between the plantations and their adjacent natural forests is not significant;the difference of species diversity of total insect communities,herbivorous insects and spider function groups between the plantations and the adjacent natural forests is also not significant.However,the species diversity of predatory and parasitic insect function group shows significant difference.The diversity of predatory insect function group in plantation is significantly lower than that in natural forests,and the diversity of parasitic insect group in plantation is significantly higher than that in natural forests.更多还原
