Abstract:

The sample plot investigation and stem analysis have been conducted so as to study the growth law of Machilus pauhoi and to analyze the relationship between its growth and the environments in Anfu county and Jian county ,Jiangxi province The results indicate that:(1) Machilus pauhoi,an indigenous tree species, grow quickly, but grow slowly in the early 5 years (2) According to average growth increment, the diameter at breast height of 50-year-old tree is 0.64 cm·a-1, its height is 0.45m·a-1 and its volume is 0.0169 m3·a-1; (3) In the growth process, there are two peak growth periods for it. The peak growth periods of diameter at breast height are among the 15th~20th year and the 40th~45th year. The peak periods of height are among the 5th~15th year and the 35th~40th year, and the peak periods of tree volume are among 20th~25th and 40th~45th year. (4) The site condition has more influences on the early 20 years growth than on mid later term growth. (5) The woodland in the 300~500 m's altitude with slate forming soil, rich organic matter and slope angle under 25, is most suitable for its growth.
