Abstract: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 ...
