Abstract: To study the structure and population dynamics of Fagus lucida,as well as its distribution pattern,the study was carried out in a 5 hm2 permanent plot established in the north slope of Baishanzu Nature Reserve,Zhejiang Province. Size structure and index of assembling intensity (K) were analyzed. Results at fourteen growth stages,based on diameter at bright height (DBH),showed that stages 1 and 2 comprised only 4% of all individuals,stages 4 to 9 made up 80%,and stages 10 to 13 accounts for 13%. Also,K for small trees (1.0 cmDBH<7.5 cm) was 0.588,for seedlings (DBH<1 cm) it was 0.029,for middle-sized trees (7.5 cmDBH<22.5 cm) it was 0.143,and for large trees (DBH22.5 cm) it was 0.169. Thus,Fagus lucida population structure was a spindle-type with the population declining due to lack of seedlings;whereas K revealed that spatial distribution was random for small trees but clumped for seedlings,middle-sized trees,and large trees,as a result decided mainly by interactions of biological and ecological properties like the inter-competition and density limitation,as well as environmental factors like drought and storm.[Ch,1 fig. 2 tab. 37 ref.]
