摘　　要：分别以单一树种与复合树种作为模拟对象,采用LINKAGES模型模拟预测了气候变暖对小兴安岭主要树种的潜在影响,结果表明:气候变暖对各树种的影响趋势与增温幅度关系密切。当温度上升不超过3℃时,云杉、枫桦将面临退化危险,但红松及其他阔叶树种的生长优势均更加明显;当温度上升超过5℃时,大部分树种均显示出不同程度的衰退趋势,仅蒙古栎等耐高温、干旱的阳性树种能够较好地适应未来的高温环境。Potential impact of climate warming to major tree species in Xiao Hinggan Mountains on single tree species and compound tree species was predicted respectively with LINKAGES model.The results indicated that there was a close relationship between the range of temperature increasing and the impact tendency of climate warming to major tree species.When temperature went up less than 3 ℃,Picea spp.and Betula costata would face the danger of degeneration whereas the growth superiority of Korean pine and other broadleaf species were more significant.When temperature went up more than 5℃,most of the species showed declining tendency with different extent,of which only heliophilous species such as mongolican oak could adapt to the future environment with high temperature.
