兴安落叶松人工林最优密度探讨

Preliminary Stupy on Plantation Optimal Stand Density of Larix gmelini Rupr.

本文应用动态规划法探讨了兴安落叶松人工幼中龄林的最优密度.文中以解析木资料为基础数据,以林分生长全过程中的采伐收入最高为目标,提出了各地位指数、各年龄阶段的林分最优密度和定量间伐的部分指标,并对应用同一资料按不同间隔阶段进行分析对比的方法做了探讨.

The optimal stand densities and quantitative thinning of young and middle-aged Larix gmelini Rupr.plantations were studied using dynamic programming.Based on basic data sources from analytic trees and standard plots,each site index and optimal stand densities plus partial quantitative thinning ration for different age stands were derived.This was calculated to determine the highest income from the felling procedure during the growth and development of the stands.Furthermore,the method of using the data sources,but dividing them into different intermissions for analysis and comparison was also investigated.
