Abstract: A pulp stand of Masson pine (Pinus massoniana) with a area of 136.7 hectares was established in Nanping of Fujian Province in 1997-1998. Five years after planting, the increment, biomass, wood property, wood chemical components and its pulping property were tested. The results showed that the average volume of the stand was 14.88 m3·hm-2, which was 117.86% higher than that of the CK or 396% higher than the standard issued by State Forestry Administration. The biomass was 31.1% higher than the CK, and the biomass of stem was as high as 70.4%. Compared with the CK, the pulp stand was characterized by higher α cellulose content, lower lignin content, slenderer fiber and higher ratio of length to width. The wood obtained had heavier wood basic volume weight and higher tensile, burst and tear strength of paper. The average input per hectare of pulp stand was 13 694 RMB yuan. The NPV was 8 732 RMB yuan based on the I of 12% and the IRR was 18.2%.
