Abstract
The growth responses of Gaozhou masson pine pulpwood to 4 thinning intensities were studied by comparative analysis.The results indicate d that,under the identical characteristics of soil profile and ground vegefation in different thinning intensities,the variations of DBH and height under branch have significant differences with the maximum accretion of DBH and the lowest a ccretion of height under branch in 1.5m×2.0m stand,while the average incr ements of tree height and crown diameter were not obviously different.The aboveg round biomass increments of 1.5m×1.5m and 1.5m×2.0m stands were higher than those of other stands by thinning within 3 years.Under the comprehe nsive survey of the growth responses of pulpwood to thinning intensity and the w ood property for papermaking,the proper density of Gaozhou masson pine pulpwood should be 1.5m×2.0m with 15 years cutting period of return on hilly land of central Hubei Province.关键词
