毕节市漆树品种产量与树皮性状的灰色关联度分析

Grey Relational Analysis on Yield and Bark Properties of Lacquer Tree Species

为漆树优良品种的选择以及灰色系统理论在林业林木品种评价上的运用提供参考,对毕节市8个漆树品种红漆大木、粉皮大木、灯台大木、红尖大木、肤胭皮、粉红皮、白杨皮、青杠皮等树皮解剖中6个主要性状与产漆量的关系进行灰色关联度分析。结果表明:漆树树皮解剖的单个性状对产漆量有直接影响,其中以漆汁道直径的大小关系最重要,直接关联度达0.796 4;其次是活皮漆汁道单位面积与活皮厚度。从树皮解剖的综合性状看,漆树品种最好的依次是红尖大木>红漆大木>肤胭皮>灯台大木>白杨皮>粉皮大木>粉红皮>青杠皮。分析结果与实际生产基本一致,表明在林业生产中运用灰色关联分析进行综合评价是可行的。

To provide references for the selection of fine species of lacquer trees and application of gray system theory in evaluation of forestry tree species,the correlation of lacquer output with six main features of eight lacquer tree species,including Hongqidamu,Fenpidamu,Dengtaidamu,Hongjiandamu,Fuyanpi, Fenhongpi,Baiyangpi and Qinggangpi,was analyzed by grey relational analysis.Results：Single traits of lacquer tree bark anatomy had direct impacts on lacquer output,of which the diameter of lacquer canal was the most important with direct association degree of 0.796 4.Followed by unit area of lacquer canal of live bark and live bark thickness.As for the comprehensive traits,the best lacquer tree species followed the sequence of Hongjiandamu 〉 Hongqidamu 〉 Fuyanpi 〉 Dengtaidamu 〉 Baiyangpi 〉 Fenpidamu 〉Fenhongpi〉Qinggangpi.The analysis results were basically consistent with the actual production traits, showing that in forestry production grey correlation analysis was feasible for comprehensive evaluation.
