摘　　要：系统调查了武夷山风景区马尾松林防治区与未防治对照区标准地节肢动物群落的多样性。结果表明,防治区节肢动物群落的目、科、种和个体数量均有不同程度的下降。防治区比对照区少了2目(脉翅目和竹节虫目)4科30种2 044个个体数。对照区具有较大的物种丰富度S、个体数N、多样性指数H′和均匀度指数J和较小的优势度指数C。分析认为对照区林分的节肢动物群落稳定性大于防治区林分的。The effect of pesticide on arthropod diversity of masson pine stands in Wuyi Mountain scenic spot was studied. The results showed that, compared with untreated stands, pesticide application decreased the number of arthropod order, family, species as well as individual. The insects from Neuroptera and Phasmida were not found in pesticide treated stands, which caused the number of family decreased by 4. Also, the number of arthropod species or individuals was 30 or 2 044 less in pesticide treated stands. In the untreated stands, the value of S, N, H＇or J was higher, but that value of C was lower. Summarily, pesticide application lessened the stability of arthropod community in masson pine stands.
