摘　　要： 对福建中部山地不同密度湿地松林分的研究表明， 湿地松速生期早， 是培育短周期纸浆林的优良树种， 也是采脂的良好树种。湿地松纸浆林树冠重叠系数为１０７１ ５ 时， 可实现短周期内较高的蓄积量， 同时单株充分生长， 以利采脂。建立了湿地松生长模型， 导出了不同林龄湿地松纸浆采脂两用林的经营密度上限。根据湿地松短周期的培育目标， 确定出湿地松纸浆采脂两用林的４ 种培育模式， 可实现林分总蓄积分别为２１０６１ ｍ ３·ｈ ｍ － ２ ， ２３５１０ ｍ ３·ｈｍ － ２ ， ２４２６８ ｍ ３·ｈ ｍ － ２ 和２７３２４ ｍ ３·ｈ ｍ － ２ ， 并可采脂１０ ａ 。表５ The slash pine forest stands with different densities in mountainous region of the middle part of Fijian were studied.The results showed that the rapid growth period of slash pine was early.It was not only a good tree species to be cultivated for paper pulp wood of short cutting period but also a fine tree species for resin.When the overlapping coefficient of crowns of paper pulp forest stands was 1 071 5,the stand could reach a bigger stock and the single tree could fully grow for resin.The maximum management density of the stands for paper pulp and resin was cal culated out by the growth model.Four cultivation patterns of slash pine forests for paper pulp and resin were defined according to the cultivation arms of short cutting period.The forest stands of four different patterns had a series of gross stocks of 210 61 m 3·hm -2 ,235 10 m 3·hm -2 ,242 68 m 3·hm -2 and 273 24 m 3·hm -2 and their resin could be collected for ten years.The conclusion could be referred for forestry production.
