We studied the growth process of three cypress trees by stem analysis ( Chamaecyparis obtuse, Thuja standishii and C. pisifera) .For three species , the growth of DBH ( diameter at breast height ) had nearly no increase in the first 3-4 a after planting.The annual growth curve and the average growth curve of Chama ecyparis obtuse and C.pisifera intersected in for-estation after 8-9 a, and the successive growth started to be lower than the average growth rate 11-12 a after planting T. standishii.DBH of vigorous growth period appeared during 8-15 a after afforestation , and the three cypress tree stands should be thinned after 10 a of afforestation .The growth of height increased rapidly in the first 10 a of afforestation , and its vigorous growth period lasted for 5-10 a, and the current annual increment curve and average growth curve intersected after afforestation 9-11 a.Annual and average volume growth quantity growth turned slow in the 0-20 a afforestation , and after 20 a of afforestation, C.pisifera volume successive growth was significantly greater than the other two species , the volume order of timber is C.obtuse (02.48 7 m3), T.standishii (0.253 6 m3), and C.pisifera (0.317 2 m3).After 35 a afforesta-tion, forest stands of the three species were not maturity demanded forest tending and management measures to cultivate the cypress big diameter timber .
