摘　　要：对常年用人工或除草剂除草的茶园(单一园)和在地面种植长耳节草Hedyotisuncinella的茶园(复合园)的昆虫类群进行了调查,并对昆虫类群结构和类群主要特征进行了分析.结果显示,单一园调查到11目62种370头个体昆虫,而复合园有11目75种337头个体昆虫.复合园昆虫类群丰富度值为3 8035±0 2682,高于单一园值3 3318±0 2481;复合园Shannon Weiner多样性指数(3 1064±0 1392)显著地高于单一园相应值(2 6077±0 1941);复合园昆虫类群均匀性指数比单一园的高,而类群优势集中性指数比单一园的低.Investigations of insect assembly in tea tree habitat both in simplex tea orchard without weeds (STO) and complex tea orchard with weed Hedyotis uncinella (CTO) were conducted. The structures and main eigenvalues of insect assembly were explored and analyzed to assess the effects of different type of orchards on diversity and stability of insect assemblage. The results indicated that insects of 11 families, 62 species and 370 individuals were collected in STO, while insects of 11 families, 75 species and 337 individuals in CTO. The average value of richness index (R) of insect assembly in CTO was (3.803 5)±(0.268 2), higher than that in STO ((3.331 8)±(0.248 1)). The average value of diversity index (Shannon-Weiner index) in CTO was (3.106 4)±(0.139 2), significantly higher than that in STO ((2.607 7)±(0.194 1)). Insect assembly in CTO had higher evenness index (J), while with lower concentration index (C).
