摘要
本文对邵武市卫闽林场的16和18指数立地上，不同密度15年生杉木立木蓄积量和可生产的不同规格杉木原条出材量，进行经济核算，结果表明；16指数立木造林密度1410株／hm^2的立木蓄积量比同指数630株／hm^2密度增产69．0％；比18指数密度630株／hm^2的林分增产36．3％。该林分的综合经济效益占第二位。
The results reveal that the stocking of the plantiong density (1410 trees/hm2)of 16-index increasesby 69. 0% as compared with that of the planting density(630 trees/hm2)of the same index and increases by36. 3% as compared with that of the plsnting density(630 trees/hm2)of 18-index,but the comprehensive economic benefit of this stand ranks second.
