| 摘 要： | 杉木与拟赤杨混交类型应选择在缓坡，低洼，有季节性积水的地块造林，采用１：１行间混交方式，这样可以形成相对稳定的复层林相，经济效益显著；但在大多数山坡地块上，到中龄林时形成了同层林，拟赤杨有被淘汰的趋势，而杉木长势良好，高径生长量比纯林杉木显著。

| Abstract: | The mixed forest of Cunninghamia lanceolata and Alniphgllum fortuneishould be made on the site which is a gent le slope,low-lying and seasonalaccumulated water zone,by rows mixed at interval of 1 :1.This mixedforest has a relative stable forest form(multi-storied stand)and has a sig-nificant economic benefit.The bulk of mixed forest, however, become frommulti-storied stand to even-storied stand at haif-mature forest.So thegrowth of Alniphyllum fortunei is in bad, and the increment of Cunninghamialanceolata is bigger than that of the pure forest. |
