闽北木荷人工林生产潜力的研究

Potential productivity of Gugertree plantations in North Fujian Province

本文利用数量化理论建立数量化优势高生长模型,复相关系数达0.9,T检验结果表明,木荷林分优势高与各因子间存在着极显著的相关。坡形、土壤A+AB层厚度、质地、紧实度和经营水平是最重要的因子,坡位、坡向和造林地前身也有一定的作用。根据数量化立地指数得分表划分立地类型,以探讨木荷在各立地上的生长趋势并对立地质量进行了评价。本文还对木荷造林地的选择作了初步探讨。

Growth model of digitizing dominant tree height of Schima superba was established by digitizing theory. The multiple correlation coefficient was up to 0.9, T test shows that the dominant heights of Gugertree plantations were significantly correlated to the factors used. This result shows that slope form, depth of A+AB soil horizons, soil texture, soil compaction and management level are very important factors, and slope position, slope direction and to the scores of digitizing site indices, site types were determined to investigate the growth tendencies of Gugertree plantations under diffeient conditions, and the site quality was evaluated. The selection of Gugertree planting sites was also discussed.
