基于标准林的森林抚育诊断决策系统初步研究

森林抚育诊断决策系统以抚育经营小班为对象，根据森林演替规律，依据森林经营技术规程和研究成果，生成树种结构和空间结构理想化的标准林，通过对比分析现有林与标准林因子的差异，诊断决策现有林“是否需要抚育”及“如何抚育”。以松江河林业局前川林场（sjq31-1）小班和神农架林区徐家庄林场庙坪村（xjmp-2）小班作为对象，开展诊断林分结构现状的研究。结果表明：FTDDSS 具有生成标准林、诊断林分树种组成和空间结构及提出森林抚育决策意见的能力，可以作为开展森林抚育设计决策的辅助工具。

Preliminary Research on the FTDDSS Based on Standard Forest

Tending and management subcompartment was taken as objects,by Using the FTDDSS,a standard forest with ideal structures of tree species and space was generated based on the succession rules of forest and the current technical regulations,research results and policies. Through the contrastive analysis of the differ-ences between standard forest factors and existing forest factors,the FTDDSS would decide whether the existing forest need tending and how to tend. Viewed from the present application,the FTDDSS can serve as an auxilia-ry tool to carry out forest tending design and with the ability to diagnose the species composition and space structure of stand,and to put forward the tending decisions and opinions.
