摘　　要：对化防区、生防区、混防区3个不同类型美国杂交杏李园中捕食性节肢动物群落的结构、动态等方面进行了研究。结果表明:混防区中的天敌密度与生防区中的差异不显著,而生防区能有效地控制害虫数量,生防区和混防区中捕食性节肢动物群落的平均密度和种类高于化防样田,表明化防区对天敌的影响很大。生防区和混防区天敌群落的物种丰富度、多样性和均匀性高于化防区,且随着农药使用水平的增强,美国杂交杏李园中占统治地位的天敌种群趋于集中。The structure and dynamics of the predatory arthropod communities were analyzed in chemical control natural garden, biological control garden and mixture control garden. The results showed that the density difference of enemies was not significant between biological control garden and mixture control garden, but the pests were controlled effectively in biological control garden. The density and types of predatory arthropod community in biological control garden were higher than that of chemical control natural garden. It showed that the natural enemies were impacted in chemical control garden. The species diversity, abundance, and evenness of natural enemy communities in biological control garden and mixture control garden were higher than chemical control garden, the main enemies populations tends to concentrate when the pesticide were used.
