摘要：利用造林密度对比试验与现有人工林分密度的调查结果，提出马尾松速生丰产林的适宜造林密度与不同培养目标的林木密度调控模型。结果表明：马尾松速生丰产林的造林密度以中密度为宜，植距在１．４ ｍ ×２．０ ｍ 和２．０ ｍ ×２．０ ｍ 之间，每公顷３ ５５５～２ ４９０株。试提出不同培养目标的林分密度调控管理模型如下：（１）小径材（１２～１６ ｃｍ ），伐期２０ ａ，立地指数１４～１６，造林密度３ ６００～３３００株·ｈｍ － ２、最终保留密度２ ３４０～２ １４５株·ｈｍ － ２，年均材积生长１１．６１～１４．５４ ｍ ３·ｈｍ － ２。（２）中径材（１８～２４ ｃｍ ），伐期２５ ａ，立地指数１６～１８，造林密度２ ７７５～２ ４９０株·ｈｍ － ２、最终保留密度１ ５６０～１ ３９５株·ｈｍ － ２，年均材积生长１３．０２～１７．４７ ｍ ３·ｈｍ － ２。（３）大径材（２６～３２ ｃｍ ），伐期３０ ａ，立地指数１８～２０，造林密度１ ９９５～１ ７２５株·ｈｍ － ２、最终保留密度９００～７５０株·ｈｍ － ２，年均材积生长１６．２０～１６．７６ ｍ ３·ｈｍ － ２。
Data from spacing experiments and stand density investigation of current plantations were used to determine suitable planting density of masson pine ( Pinus massoniana ) high yielding plantation and establish adjustment and control models of stand density (A & C Models)for different cultivation objectives.The results showed that middle planting density with spacing from 1.4 m×2.0 m to 2.0 m×2.0 m (3 555～2 490 trees per hectare) was optimum for high yielding plantation of masson pine.A & C Models for different cultivation purposes were as follows:(1)For cultivating small diameter timber with DBH 12～16 cm,the rotation was 20 years,site index was 14～16,the planting density was 3 600～3 300 trees per hectare and final remained density 2 340～2 145 trees per hectare,the annual mean volume increment 11.61～14.54 m 3·hm -2 . (2)For cultivating middle diameter timber with DBH 18～24 cm,the rotation was 25 years,site index was 16～18,the planting density was 2 775 ～2 490 trees per hectare,the final remained density 1 560～1 395 trees per hectare,the annual mean volume increment 13.02～17.47 m 3·hm -2 . (3)For cultivating large diameter timber with DBH 26～32 cm,the rotation was 30 years,site index was 18～20,the planting density was 1 995～1 725 trees per hectare,final remained density 900～750 trees per hectare,and the annual mean volume increment 16.20～16.76 m 3·hm -2 .
