摘要 通过对马尾松自然分布区内14个天然群体木材化学组分的分析和浆纸性能的测试,发现木材戊糖,灰发含量,纸张抗张,耐破和撕裂强度呈现随纬度变化的地理模式,与经度无关。和北部天然林相比,南部林分的木材戊糖和灰分含量较低,在相同的蒸煮条件下,浆的Kappa值较高,张纸抗张和耐破指数较低而撕裂指数较高。木材α-纤维素、木素、苯醇抽出物含量以及制浆得率与经纬度无关。研究还发现木材灰分含量和纸张撕裂指数与树木年龄 Through analysizing on the chemical components in wood and pulp/paper-making properties of l4 natural populations covering over the distribution range of massonpine,it was found that there exisit latitudinaI trends for pentosan and ash content in woodand tensile,burst and tear strength of paper which are less effected by the longitude。Com-paring the natural stands from the north,the ones from the south possessed less pantosanand ash content ,higher Kappa value of pulp under the same pulping conditions ,lower ten-sile and burst index and higher tear index. No definite geographic patterns were exisited for-α -cellulose,lignin,alcohol-benzene extractives content in wood and pulp yield.The ash con-tent and paper tear index was found to be also influenced by tree age. The age effects of theother traits were small。
