摘　　要：以贵州省台江县马尾松纸浆用材林１２ 年生系列试验林的实测资料为基础，结合各项试验林经营的实际费用发生额，用动态分析方法对各试验林分进行了初步的经济效益评价分析。结果表明：在贵州东南部地区，选用广西桐棉种源育苗，造林初植密度在每公顷３３３０株，采用块状整地，造林时每株施６０ｇ钙镁磷肥作底肥或造林后第２年施３０ｇ复合肥，是马尾松纸浆林在经济上较优的栽培模式。Based on document of a series of 12-years Pinus massoniana forest for pulpwood in Taijiang county,Guizhou province and real management cost, dynamic analysis on Preliminary economic performance of experimental stands resulted that in the southeast of Guizhou provinc,an improved cultivation mode was recommended for P.massoniana forest for pulpwood with provenance from Tongmian of Guangxi province, 3330 seedlings per hectare, land preparation in patch, 60g calcium magnesium phosphate per seeding as base fertilizer or 30g compound fertilizer the next year.
