Broad-leaved secondary forest is one of the important forest types in the south of Jiangxi Province,and its quality affects forest functions.This study took the broad-leaved secondary forest in southern Jiangxi as the research object,selected two types of broad-leaved secondary forests after multi-function forest management,and studied the response rule of the average annual growth rate of the dominant tree species in different forest layers to different management modes.The main conclusions are as follows:(1) after three years of operation,the average basal ares growth of the operational and comparative lands did not grow significantly,Pr(>F)=0.188;(2) forest layer is an important index that affects the growth of broadleaved secondary forests.In the main forest layer,the average annual growth of the basal area was the highest,followed by the middle forest layer,and the under forest layer was generally lower.(3) The cumulative basal area of dominant tree species such as Castanopsis carlesii,C.chinensis,Schima superba,C.fargesii and so on is large,and its growth is obviously higher than other tree species.This study can provide the basis and reference for improving the forest quality of broad-leaved secondary forest.
