摘 要:采用不同比例的新疆杨、臭椿营建混交林,对不同混交比例类型的新疆杨和臭椿的树高、胸径、单株材积和受天牛虫害情况进行调查与分析,结果表明:新疆杨和臭椿混交,2个树种的生长量较纯林相比有所下降,天牛对新疆杨的危害程度因比例类型而不同.其中,1∶1(行间混交)行状混交,2个树种的生长量最低;2∶3(2行新疆杨,3行臭椿)带状混交,新疆杨受天牛危害的虫害率和单株虫粪孔数均为最低.Different mixed forest models of Ailanthus altissima and Populus bolleana were surveyed, and then the DBH, height, volume and the Anoplophora glabripennis' damage to Ailanthus altissima and Populus bolleana were comparably analyzed. It was concluded that the growth quantities of the two tree species were decreased in all mixed forest stands, of which, the growth of the mixed model of the 1 : 1(the proportion of individual quantities for Populus bolleana and Ailanthus altissima) was lowest, but the damage rate caused by Anoplophora glabripennis for the 2 : 3 model was lowest.
