Abstract:

Through regular and systematic surveys in five selected sampling plots of Phyllostachys heterocycla cv. pubescens forests managed with five different and typical measures respectively, including cultivation and fertilization, cultivation, weeding, spraying herbicide and non-management in Sanming of Fujian Province, China from 2001 to 2002, the effects of these measures on the composition and structure of arthropod community were studied. The results showed that in contrast with the non-management forest, the richness of the community decreased for the disturbances of the other four management measures. The missing species in the lower layer mainly belonged to Araneida, Hymenoptera, Hemiptera and Coleoptera, and those in the canopy mainly belonged to Hymenoptera and Coleoptera. Most of the missing species in the community were rare species (Pi<0.01). In the lower layer, due to the disturbances of cultivation and fertilization, cultivation and weeding, the individual number of the neutrals increased, but that of the predators decreased. In the canopy, the individual number of the predators increased, but that of the herbivores decreased due to the disturbances of cultivation and fertilization, cultivation, weeding and spraying herbicide. In general, the species diversity and evenness all decreased in the lower layer, but increased in the canopy due to the management disturbances. Among the four measures, spraying herbicide disturbed most slightly in the lower layer, and cultivation most slightly in the canopy. Moreover, long-term non-management and cultivation could benefit higher dominant degree of phytophagous mites, and long-term non-management, weeding and spraying herbicide could benefit higher dominant degree of Kuwanaspis vermiformis, and long-term cultivation and fertilization, cultivation and weeding could benefit higher dominant degree of Pantana phyllostachysae. This indicated that long-term management with single type of measures would result in outbreak of certain pests. It was so concluded that in the management of P. heterocycla cv. pubescens forest, it was necessary and important to manage with manifold measures alternately in different years.
