摘　　要：为有效增加黑龙江省西部地区的造林树种,改善当地的森林结构,特从外地引选了班克松、红松和长白松3个造林树种。根据12 a的调查,3个树种均能在该区正常生长,从苗高、胸径、冠幅几方面看都不比当地的樟子松弱,并且具有一定的耐寒、耐旱特性。3个树种不仅能正常生长,并能开花结实,说明这3个树种均能适应试验地区的气候。In order to effectively increase afforestation species in western part of Heilongjiang province and to improve local forest structure,3 afforestation species（Pinus banksiana,Pinus koraiensis,Pinus sylvestriformis）from other places were especially introduced.Three species which can grow normally in this area according to 12-years＇investigation are no weaker than local Pinus sylvestris var.mongolica from seedling height,DBH crown;they can also resist cold drought.Three species can not only grow normally,but also bloom and fruit.It illustrates that these 3 species all can adapt climate in the testing area.
