Abstract: In order to clarify the spatial distribution of climate suitability and disaster risk of staple crops, specialty crops and facility crops, refined climate suitability regionalization for rice and facility agriculture, and disaster risk zoning for rice cold damage and wine grape frost were conducted. Taking Yongning County as an example, the data from auto meteorological stations were used in the research, and some methods including qualitative judgment, cluster analysis, spatial analysis and so on were adopted. The suitable planting areas, less suitable planting areas and unsuitable planting areas were determined for advantage agriculture, specialty agriculture and facility agriculture. The results showed that most part of Yongning County was suitable or less suitable for rice production and facility agriculture; the low risk areas of rice cold damage and wine grape frost were along Helan Mountain, and the high risk areas were in Minning town, the middle and west part of Lijun town, and the west part of Wanghong town. The analysis had certain significance for exerting regional climate advantage, avoiding disadvantages, reducing the loss from meteorological disasters and increasing the overall benefit of all kinds of industries. The achievement could provide decision support for the government of Yongning County in planting structure adjustment and disaster prevention and mitigation.
