Complex tea orchard with ground cover plant Hedyotis uncinella Hook & Am (Rubiaceae, Hedyotis) was established in Hongxing Tea Plantation, Yingde city, Guandong province. In order to gain more knowledge of the arthropod assemblage structure, the values of assemblage diversity index (H), species richness index (R), evenness index (J), species dominance index (d) and assemblage concentration index (C) of tea tree habitat were calculated and their relationships were studied using the methods of Factor Analysis and Path Analysis. Results of Factor analysis showed that the five primary eigenvalues of arthropod assemblage comprehensively fell into three principal components. The first principal component mainly represented assemblage diversity and evenness. The second and the third components largely stood for species richness and assemblage concentration index, respectively. The proportions of variance of the three principal components were 50.279%, 26.92% and 22.466%, respectively. Path Analysis outcomes indicated that the diversity of arthropod assemblage had a significant and positive correlation with the species richness of arthropod assemblage and natural enemy assemblage, while a significant and negative correlation with assemblage concentration index. Thus, the diversity of arthropod assemblage could be increased by promoting the species richness of arthropod assemblage and natural enemy assemblage, whereas decreasing assemblage concentration index through establishing complex tea plantation.
