西双版纳造林树种的灰色局势决策

西双版纳是我国树种资源极其丰富的地区之一。本文在木材物理、力学性质测定和小面积造林实验的基础上,对已经成林的初步筛选出的23个树种,选取年树高生长量、年胸径生长量、木材气干容量、抗压强度、抗弯强度、冲击韧性和端面硬度7个表征造林树种速生珍贵的指标,应用基于灰色关联度的聚类分析方法,对西双版纳造林树种进行了灰色局势决策。结论:榆绿木、铁刀木、团花和山桂花四个树种应排在西双版纳营造用材林树种的首位。

A GREY SITUATION DECISION FOR PLANTATION TREES IN XISHUANGBANNA

Xishuangbanna is one of the regions that are rich in tree resources in China. On the basis of plantation on small scale and wood propery experiment on annual mean height in- crements,annual averege diameter increments,wood weight by colume,compressive strength,flexural strength,toughness and cross section hardness,23 species of valuable cabinet timbers in Xishuangbanna,are selected in plantation as target for grey situation decision by application of grey clustering method. The results show that Arogeissus accuminata,Cassia siamea,Anthocephalus chinensis and Paramichelia baillonii should be placeed in the first position for plantation in Xishuangbanna.
