Gale disaster is one of the main meteorological disasters affecting the facility agriculture production in Inner Mongolia. To provide a scientific basis for the planning and layout of facility agriculture, based on the field survey data of gale disaster of facility agriculture, ground wind observation data and greenhouse wind load indicators, we calculated the solar greenhouse gale indexes and graded the warning levels of gale disasters, and by constructing gale disaster assessment model of facility agriculture, we studied the wind resistance capacity of solar greenhouse in different areas of Inner Mongolia. The results showed that, from the comprehensive risk index of solar greenhouse gale disaster, the middle and high risk areas were mainly concentrated in the central and western regions of Inner Mongolia, and the gale disaster risk was generally high in the mountainous areas, especially in the northern piedmont area of the Yinshan Mountains in spring and autumn. This area, with more windy weather, strong risk index, high altitude and large population density, had high risk sensitivity and exposure degree, which could be the main gale disaster factors for facility agriculture. So, the development of facility agriculture in this area should be more cautious on avoiding gale weather. Gale risk was low in the Yanshan hilly area of southeast Inner Mongolia, which was suitable for the development of solar greenhouse. This research could provide technical support for the early warning service on gale disaster risk and the formulation of gale disaster prevention measures for facility agriculture in Inner Mongolia.
