【摘要】According to sampling of arthropod in the inefficient Larix pricipis - rupprechtii forest, the arthropod community composition was preliminarily analyzed. And sampled to 5 areas in different management measure,compared the species composition, Shannon- Wiener diversity index,Evenness and Similarity index of the different sample plots of the plantation.The results showed that 'manual promote renew' has the highest species diversity,The overall level of species diversity of the plantation is higher then the usual plot without? Manual processing.%通过对冀北山地华北落叶松低效人工改造林的节肢动物取样调查,采得节肢动物2纲9目60科177种3 985头.并初步统计分析该低效人工林的节肢动物群落组成,对人工林中5种不同处理样地进行分别取样,分析比较各样地节肢动物群落的物种组成、多样性指数、均匀度、相似性指数.结果表明:人工改造林中节肢动物多样性整体水平比未经处理的对照林略高,其中,人工促进更新的针针混交乔灌草复层结构林(样地1)的节肢动物多样性水平最高. 【总页数】4页(268-271)
