| 摘 要： | 大风灾害是影响内蒙古设施农业生产的主要气象灾害之一,为给内蒙古设施农业规划布局提供科学依据,结合实地设施农业大风灾害调查数据,以地面大风观测资料和温室风载荷指标为基础,计算日光温室大风致灾指标,进行大风灾害预警等级划分,并通过构建设施农业风灾评估模型,研究内蒙古不同地区日光温室的抗风能力。从日光温室大风灾害综合风险指数来看,中、高风险地区主要集中在中西部地区,沿山地区风灾风险总体较高,尤其是阴山北麓地区,春、秋季灾害风险较高。原因是该地区主要成产季大风天气较多,危险性指数较高,同时阴山北麓地区海拔较高、人口密度较大,敏感性和暴露度较高,成为影响设施农业生产的主要风灾因子,因此,阴山北麓区在发展日光温室时要尽量避免大风天气的影响,东南部燕山丘陵地区风灾风险较低,考虑风灾的影响,该地区最适宜日光温室发展。本研究可为内蒙古设施农业风灾风险预警服务及风灾防御措施的制定提供技术支撑。

| Abstract: | 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. |
