| 摘 要： | 以湖北省太子山马尾松密度试验林为材料，运用动态规划的方法，在生长收获预估模型系统的基础上，以最大经济收益为目标函数，建立了立地指数为14.6的林地种植马尾松纸浆林的合理经营密度表，得到了不同初植密度（6667株／hm^2、4444株／hm^2和3333株／hm^2)的林分各经营时期的间伐强度、间伐次数和间伐间隔期，从而指导湖北省马尾松纸浆林的生产。结果还表明：高初植密度不能提高培育马尾松林的经济效益，合理间伐可获得较好的收益。

| Abstract: | On the basis of growth and yield model system, according to the density experiment stands of masson pine in Taizishan of Hubei Province and taking the largest economic benefit as the aim function , the best management density table of masson pine pulp plantation with site index 14.6 have been established by using dynamic planning . Then the thinning times, thinning intensity and interval terms of thinning for the largest gains of masson pine pulp plantation in various stage can be obtained by using these tables, which may be used as a guide to real practice. And the results show that the pattern with high planting density can not result in good economic benefits, and rational thinning can raise economic benefits. |
