%X The effects of selective cutting of different intensity on the tree layer structure and species diversity of evergreen broadleaved forest(low intensity,13.0%;middle intensity,29.1%;high intensity,45.8%;over-high intensity,(67.1%)) were surveyed and analyzed.The results show that the selective cutting of low and middle intensities caused a light variation to the tree layer structure,but the selective cutting of high and over-high intensities caused changes of the tree layer structure to some extent.The cutting operation results in adverse influences on the development of tree layer species diversity of evergreen broadleaved forest,particularly the serious damage to the forest canopy caused by selective cutting of high intensity.But the rational selective cutting benefits the restoration and maintenance of species during a long time,which may result from the different variations of such environmental factors as sunlight,temperature and humidity,etc caused by cutting operation.
