中文摘要	分析20世纪90年代以来有关气候变暖及其影响的研究数据,得出如下结论:中国三北地区气候正经历着暖干化的变化,未来几十年此种趋势将更加明显,位于三北东部的东北地区尤为突出.气候暖干化将带给三北防护林工程3方面的压力:1)干旱区和荒漠化面积扩增;2)自然植被分布格局发生变化,自西向东的植被逆向演替,众多的过渡带变化敏感;3)现存的防护林在气候变异的干扰下衰退的风险加剧.应对气候变化,三北防护林建设宜采取如下策略:1)增加建设规模;2)植被疏林化和灌丛化作为过渡带防护林设计的目标;3)在水土流失区以原生化建设模式设计油松人工林;4)制订三北防护林经营技术方案.
英文摘要	Through the analysis on the research data about climate wanning and its effects on the Three-North Regions since the 1990’s, a trend was found that the Three-North Regions of China was suffering the climatic warming and drying, which would be more obvious in the coming dec-ades, especially in the northeastern part of China. This trend would give stresses on the Three-North Shelter Forest Program in the aspects of 1) expansion of arid area and desertification, 2) changes in the distribution pattern of natural vegetations,i.e. , a converse succession from the west to the east and the appearance of many sensitive ecotones, and 3 ) decline risk faced by the existent shelter forests. Aiming at these stresses, four strategies were suggested: 1 ) increasing the construction scope, 2) taking vegetation thicketization and open forest as the goal of desig-ning shelter forest ecotone, 3 ) designing Pinus tabulaeformis plantations based on original vegeta-tion pattern in the area at water and soil loss, and 4) drawing up a technical program for the management of shelterbelts in the Three-North Regions of China.
