摘要: 针对目前三北地区防护林出现的衰退、死亡等问题,探讨了该区林木生长的气候生态适应性,并指出这种现象的出现与当地恶劣的气候条件有很大关系。其中,限制三北地区防护林正常生长发育的主要气候因子是降水量不足、蒸发量过大,其次为风大且持续日数长;而温度与日照则不是限制三北地区防护林生长的气候因子。基于此,从气候生态适应性角度出发,提出因地制宜合理营造三北地区防护林的建议。

Abstract: Aiming at the deterioration and death of shelter forests in the Three-North Regions, the climatic ecological adaptation of the forests during their growth period was discussed. The deterioration and death of shelter forests in the Region was mainly due to atrocious weather. Deficient precipitation and high evapotranspiration were the most important factors restricting the normal growth of the shelter forests, followed by lasting strong wind, while temperature and sunshine had lesser effects. From the viewpoints of climatic ecological adaptability, some
suggestions were proposed for the rational construction of shelter forests in different areas of Three-North Regions.
