摘　　要：为了科学开展设施农业建设,避免盲目扩大产业规模所带来的潜在风险,本研究利用赤峰市14个气象站近30年(1989—2018年)的气象观测资料,分析了影响设施农业生产的关键气象因子,确定了以年日照时数、冬季平均最低气温为设施农业气候资源区划指标,以年大风日数、年冰雹次数、年大雪及以上降雪次数和冬季≤-25℃低温日数为设施农业气象灾害区划指标。基于GIS技术,运用回归分析和薄盘样条对区划因子进行空间插值,制作了赤峰市设施农业气候区划图。结果表明:适宜区和次适宜区主要集中在赤峰市中东部和东南部,该区域海拔低,地势平坦,热量和光照充足,气象灾害相对较少,适宜发展设施农业;北部和西北部地区,以高山和丘陵为主,海拔高,热量条件不足,气象灾害多发,不适宜设施农业建设。To carry out the construction of facility agriculture and avoid potential risks brought by blind expanding of industrial scale,using the meteorology dataset of 14 stations in Chifeng for the past 30 years(1989-2018),the key meteorological factors affecting facility agriculture were analyzed.Two climatic resource variables,including annual sunshine hours and average minimum temperature in winter,and four meteorological disaster variables,including annual gale days,annual hail frequency,annual snowfall times over 10 mm and days with daily minimum temperature less than or equal to -25℃ in winter,were selected as the major indexes for determining the suitable area for constructing facility agriculture.Based on GIS,using regression analysis and TPS,the author made spatial interpolation of regionalization factors and produced the climatic regionalization map of facility agriculture in Chifeng.The results showed that the suitable area and the sub-suitable area are mainly concentrated in the east-central and southeast of Chifeng,which has low altitude,flat terrain,sufficient heat and light,relatively fewer meteorological disasters,and suitable for the development of facility agriculture.The north and northwest of Chifeng are dominated by mountains and hills,with high altitude,insufficient heat condition and frequent meteorological disasters,which are not suitable for the construction of facility agriculture.
