摘 要：Field trials were carried out from June to August in 2004 at Wuyishan （Wuyi Mountains）, Fujian province, China, to determine the effects of habitat diversification on arthropod communities. Two Chinese cabbage, Brassica chinensis, field 1 （F1） and field 2 （F2） surrounded by diverse vegetable cultivars were selected, while a monoculture of Chinese cabbage served as the control field （CK）. The results showed that： （i） when comparing insect abundance of each order between different habitats, significantly higher numbers of lepidopterous insects （39.76% from the each order） and lower densities of Hymenoptera （19.82%） were found in CK than in F1 and F2; （ii） compared with CK, F1 and F2 had a lower percentage of species richness and an abundance of herbivorous insects, but increased richness, abundance and biodiversity of predatory insects; （iii） no differences were observed in neutral insects＇ guild between different fields; and （iv） the dominant species for each guild depends on the habitat types and sampling dates. This study suggests that intercropping could conceivably be used in these habitats to increase the population of natural predators, thus achieving desirable and ecologically friendly results in vegetable fields.
