Population Structure of Livistona speciosa in Nuozhadu Nature Reserve
摘要
Abstract
Distribution features,population density,high structure,natural regeneration and seedling growth process of Livistona speciosa in Nuozhadu Nature Reserve were investigated by means of route survey,simple inves-tigation.Results showed that L. speciosa was intensively distributed in the Lancang River West Bank and southern Nuozhadu Nature Reserve during 730-1 500 m altitudes,in which the vegetation types were semi evergreen mon-soon forest,montane rain forest and monsoon evergreen broad-leaved forest.Moreover,semi evergreen monsoon forest was the largest and even form a L. speciosa community.The average population density was 378 plants per hectare in 1 1 sample plots,213 plants per hectare in Tea Plant plot,and 819 plants per hectare in Longtan plot. The tree layer relative abundance reached 16.67%in Tea Plant plot and 63.04%in Longtan plot.L. speciosa was a tropical tree species,but its seed germination requires a certain light intensity.Besides,the growth rate of seedling was very slow,such as the restrain the growth of seedling stage up to 5 years,and there was an irregular leaf devel-opmental phenomenon during growth and development process.关键词
