A Community Ecology Study on the Monsoon Forest in the Valley of Lower Luzhi River in Yunnan
Based on the investigation of 1 ha plot,the primitive monsoon forest on the valley of lower Luzhi River in Yunnan was studied.The height of the community is 15-20 m,and tree layers are divided into 2 layers,which is dominated by deciduous tree species Lannea coromandelica and evergreen tree species Cipadessa cinerascens.One hundred and sixteen vascular plant species were recorded from the plot,including 36 tree species,14 shrub species,43 herbaceous species,43 liana species and 2 epiphyte species.Shannon-Wienner index is 2.2824 and Simpson index is 0.8321 from the 1 ha plot.Total 1 764 trees individuals with DBH ≥ 1 cm were recorded in the plot.This community is dominated by phanerophytes.The forest is dominated by the microphyllous species which makes up 39.32％ of the total.The forest is also dominated by the species with simple leaves (make up 73.50％),papery leaves (make up 69.23％),none caudate leaves (make up 81.20％) and entire leaves (make up 67.52％).The species/area curve shows that it is flatten at 2 000 m2,which is suggested to be the minimum sampling area for the forest.This community could be recognized as Lannea coromandelica-Cipadessa cinerascens formation.
