摘　　要：根据引种的气候相似理论,选择年平均气温、1月平均气温、7月平均气温、极端最高气温、极端最低气温、≥10℃积温、年降雨量、年日照时数9个生态因子作为分析因素,采用欧氏距离模糊相先比法划分陕西省适宜栽种能源物种文冠果的区域。经分析得出陕北和渭北的黄土高原丘陵沟壑区是文冠果的最佳栽培气候区,包括子长、富县、宜川、延长、甘泉、黄龙等29个县(市);关中平原的大部分地区是文冠果适宜栽培的气候区,包括泾阳、凤翔、乾县、三原、蒲城、兴平市等37个县(市)。同时,阐明不同适宜区文冠果适宜的气候因子和限制因子。Acoording to the theory of cilimatic analogues,main factors were chosen in the analysis for the introduction of Xanthoceras sorbifolia Bge.,namely that annual average temperature,average temperature in January,average temperature in July,the maximum temperature,the minimum temperature,≥10℃ annual accumulated temperature,annual precipitation,annual sunshine hours.The suitable climatic and ecological regions for Xanthoceras sorbifolia Bge.in Shaanxi province were divided by applying euclidean fuzzy distance similitude priority ratio.Three regions were dicided favorable area,less favorable area and unfavorable area,respectively.Through the analysis,it can be seen that the northern Shaanxi and hilly and gully region of the Loses Plateau in north of Weihe River are the most suitable climate area for Xanthoceras sorbifolia,including Zizhou,Fuxian,Yichuan,Yanchang,Ganquan and 29 counties（cities）.Most areas of Guanzhong Plain are the secondary suitable climate area for Xanthoceras sorbifolia,including Jingyang,Fengxiang,Qianxian,Sanyuan,Pucheng,Xingping and 37 countries（cities）.Meanwhile,the suitable climate factors and limiting factors of different areas for Xanthoceras sorbifolia are also illustrated.
