摘    要:针对湖北省南方型杨树人工林的现实特点,根据31块详细样地资料,以密度二次效应模型为基础,利用动态规划方法,对南方型杨树人工林的最适经营密度进行了探讨,同时,在兼顾单株营养面积和群众栽培习惯,以及造林可操作性的前提下,提出了适合于南方型杨树人工林在不同立地条件下的造林株行距,可为造林施工、林分抚育间伐和综合经营提供科学依据。

关 键 词:南方型杨树  经营密度  动态规划

Abstract:According to realistic specialty in plantations for southern type of poplar in Hubei province and detailed data from 31 sample plots, the optimal management density was explored in this paper by using dynamic programming method on the basis of the secondary effect of density model. At the same time,row and plant spacing was also put forward which is suitable to afforestation under different site conditions for plantation of southern type of poplar under premise of simultaneously looking after nutrient area for single plant, culti vation habit by masses and operation ability in afforestation. These could provide a scientific basis for afforestation construction, tendering felling and comprehensive management.
Keywords:southern type of poplar  management density  dynamic programming
