STUDY ON DYNAMICS OF PUBESCENT HORNBEAM POPULATION IN KARST MOUNTAIN OF GUIYANG

In this paper, the dynamics of pubescent hornbeam populations in karst mountain of Guiyang are analysed by using the method of substitution of space for time. The results show that the spatial pattern changes from clumping type to random type, the size structure changes from growing type to declining type and the population density tends to have a negative increase, along with the population development and the succession of community.The study on pubescent hornbeam population can not only throw some light on some theoretical themes in plant population ecology studies of karst forest, but be also of practical significance for karst forest management , utilization and preservation.
