摘　　要：依据典型温棚对比试验以及气象数据,将低温冻害、寡照、风灾作为研究区域典型气象灾害,分类设计轻度、中度、重度以及特大灾害阈值指标,在此基础上引入单重灾害指数(SI)和复合灾害指数(CI)以评价灾害的风险强度。结果表明:单重灾害指数差异性明显,复合灾害指数表现为:古浪<凉州<民勤<天祝<永昌<乌鞘岭,即古浪、凉州宜作为区域日光温棚建设的首选之地,民勤要充分考虑棚型设计上的抗风性,其余地方则不适合大面积推广。研究结论不仅为日光温棚生产布局提供了依据,也填补了区域农业气象灾害评估体系的空白。On the basis of typical greenhouse contrast experiments and meteorological data,me aumors analyzed low temperature,low light and wind damage as the typical meteorological disasters in the study area,classified and designed the mild,moderate,severe and extreme disaster threshold index,then introduced the single disaster index （SI） and composite index （CO,to assess the risk intensity of disasters.The results showed that：the single disaster index difference was obvious,and the composite disaster index from small to large was that of Gulang,Liangzhou,Minqin,Tianzhu,Yongchang,Wushaoling,indicating that Gulang and Liangzhou should be the first choice for the construction of regional sunlight greenhouse;wind damage should be fully considered in greenhouse design in Minqin,and the rest areas were not suitable for the large area promotion of greenhouse.The conclusion not only provides a basis for the sunlight greenhouse production layout,but also fills the gap in risk assessment system of the regional agricultural meteorological disaster.
