Abstract:

The aim of this study was to reveal the distribution characteristics of arthropod community structure in the canopy of Artemisia ordosica shrub in desert area, and the composition and diversity distribution characteristics of arthropod community in the canopy of A. ordosica shrub in Yuyang, Yanchi and Shapotou were investigated, and the relationship between the individual number distribution of arthropod and the soluble sugar, crude protein, crude fat, soluble sugar, total N, total P and total K were correlated. The results showed that: (1) The dominant group of arthropod in the canopy of A. ordosica shrub in the three study areas were Tachinidae; the common dominant group of arthropod in Yuyang and Yanchi study areas was anthomyidae, and the common dominant group of arthropod in Yanchi and Shapotou study areas was Syrphidae; in addition, the dominant group of arthropod in Yuyang study area also included Hymenoptera, the dominant groups of arthropods in Yanchi study area also include Braconidae, and the dominant groups of canopy arthropods in Shapotou study area also include Formicidae. (2) The number of individuals and groups of canopy arthropods in Yuyang study area was significantly higher than that in Yanchi and Shapotou study areas (P < 0.05), but there was no significant difference between Yanchi and Shapotou study areas (P > 0.05). However, there was no significant difference in Shannon index and dominance index among Yuyang, Yanchi and Shapotou study areas (P > 0.05). (3) The results of RDA and partial RDA analysis showed that the total N content of A. ordosica was the main factor for the difference of arthropod population distribution in canopy. (4) The results showed that the composition of arthropod community, the number of individuals and the number of groups in the canopy of A. ordosica shrub were greatly affected by the precipitation distribution, while the diversity index was less affected.
