摘要
The effects of controlled burning of slash and burn agriculture on soil arthropod community of a 7 year tropical secondary forest in Xishuangbanna were studied.The results showed that groups of soil arthropod decreased 28.57%,and individuals of soil arthropod reduced 72.7% after burning.The composition of soil arthropod communities changed as well.The proportion of individuals of Acari,Collembola,Protura in the 0～15cm soil layer and Hymenoptera (ant) in burned leftover increased,and became dominant groups of soil arthropod communities after firing.The vertical structure of soil arthropod communities in secondary forest was disordered.There were much more groups and individuals of soil arthropod in soil bottom than those in soil surface after fire.The diversity of soil arthropod communities decreased after fire.
