通过对我国北方地区影响日光温室生产的主要气候因素进行分析,从光、温、风、雪4个方面选取了冬季总辐射、日光温室生产季(10月至翌年4月)阴天日数、年极端最低气温、冬季平均气温、生产季月最大风速均值、年最大积雪深度均值6个因子作为气候适宜性区划指标,采用加权指数求和的评价方法,在GIS技术支持下,对区划指标按照层次分析法确定的权重进行叠加,得到北方地区日光温室发展的气候适宜性区划图,为该地区合理利用气候资源、避免不利气候条件对温室的影响以及科学规划温室发展布局提供了参考依据.%In this paper, the impact of the main climate factors such as light, temperature, wind and snow, on solar greenhouse production in the northern regions of China was discussed. The indicators, i. e. , the total radiation in winter, the number of overcast days in solar greenhouse production season ( October - April in the next year) , the average temperature in winter, the annual extreme minimum temperature, the average value of monthly maximum wind velocity in production season, the average value of the annual maximum snow depth, were seleted as the suitability assessment index. A comprehensive climate zoning map was formed using the weighted index summation method with the support of GIS, which divided the climatic suitability of the development of solar greenhouse in this region into four grades: the most suitable, suitable, less suitable and unsuitable. The result will provide basis for the rational utilization of climate resourses, the scientific layout and the efficient development of solar greenhouse in this region.
