摘要
随着世界人口迅猛增长和工业化及大都市化进程的加快，原有的森林树种将会遇到与自然选择下有重大不同的环境胁迫压力。为保障人类生存环境和生活质量不再劣化，人类必须学会协助林木去更好更快地适应所遇到的各种随人类社会现代化而加剧和新出现的环境胁迫因素。低质量立地的造林利用技术和抗逆性育种就是摆在当代林学家面前的两大艰巨研究命题。为吸收国际先进经验来推动我国林木抗逆性育种事业，作者对近些年来国际林学界在这一领域取得的研究进展作了综述。
Abstract With the rapid increasing of world population and development of industriali-zation and urbanization, existing forest tree species will encounter significant envi-ronment stress different from that of natural selection. In order to improve the adaptab-ility of forest trees to the nonbiological stress caused by changing global environment,the foresters and plant physiologists have widely explored the genetic and physiologicalresponse of forest trees to different environment stress factors. The environrnent stressexerts tremendous influences on gene frequency and genetic structure through growthand propagation, and the community composition and structure change finally change.As a consequence understanding the pressure from different stresses and genetic differentiation related with plant responses is an important basis for effective resistance breeding. The feasibilrty of resistance breeding and its development in foreign countries aresummarized.
