Abstract: Pinus sylvestris var. mongholica(MP), one familiar coniferous tree species in northern China,is particularly significant for reforestation in sandy area. In recent years, the MP degradation in some areas attracted wide attention from both scholars and the public. In order to clarify the suitability of MP in northern China,we determined principle climatic factors by principal component analysis. According to climate similarity theory, we regarded Honghuaerji National Forest Park of MP as fixed sample field. With entropy weights calculation, we determined interpolated climatic similarity distances,and divided suitability region with land condition considered. The results show that: (1) thermal factor is the main climatic factors that impact introduction of MP, followed by moisture factor,light and altitude factors, and the influence of wind factor is relatively less. (2)We divided introduction district into suitable area, relatively suitable area, relatively unsuitable area and unsuitable area, there exists significant consistency between introduction division and climatic regionalization (Kappa=0.7494). (3) Suitable area mainly distributes in cold humid region (IA), sub-temperate humid region (IIA) and sub-temperate semi-humid region (IIB), relatively suitable area is mainly in the sub-temperate semi-arid regions (IIC) and part in sub-temperate humid region (IIA), relatively unsuitable area mainly locates in the warm semi-humid region (IIIB), warm arid region (IIIC) and plateau region,unsuitable area mainly distributes in the sub-temperate arid region (IID), sub-temperate extremely-arid region (IIE), temperate extremely-arid zone (IIID) and north sub-tropical humid zone (IVA). The study can provide theoretical basis and technical support for the introduction and afforestation of MP.
