Growth Properties of Three Introduced Tree Species in Lishui

Investigations were carried out in 2016 in Liandu Forest Farm of Zhejiang province on growth traits and aboveground biomass by sampleplots and analytic wood of Chamaecyparis obtusa, C. pisifera and Thuja stardishii introduced in 1979 by cuttings. The results showed that fastgrowth period of DBH of three determined species was between 10-year and 15-year and that of height was between 5-year and 10-year. Theindividual tree volume increment was gradually stable after 30-year. Above ground biomass of individual tree of tested species were 89.56 kg, 62.57kg and 68.78 kg respectively, and that of stands were159.86 t/ ha, 138.91 t/ ha and 212.74 t/ha respectively.
