摘　　要：应用风险评估技术,对云南省冬小麦干旱灾害风险进行研究,确定了各地冬小麦干旱减产的关键时段,计算了云南省各县冬小麦干旱强度风险、减产风险、抗灾性能、干旱灾损综合风险指数等,并进行了云南省各县冬小麦干旱灾损风险区划。结果表明,云南省由内陆向外部,冬小麦干旱灾损综合风险呈现逐渐加重的趋势。Based on the risk assessment technology,drought risk for winter wheat in Yunnan Province was studied,the pivotal period of winter wheat yield reduction caused by drought was set and such index as drought intensity,yield reduction risk,disaster resistance and drought loss comprehensive risk were calculated.Thus,Yunnan Province was divided into different winter wheat drought risk regions.The paper pointed out that from inside to outside of Yunnan Province,the risk of losses caused by drought for winter wheat gets higher
