摘要: 开展茶叶农业气象灾害风险评价可增强茶叶生产防御自然灾害能力。本文根据浙江省64个气象站1971—2010年茶叶气象灾害和农业统计资料,应用模糊数学和加权指数求和方法构建了茶叶气象灾害综合风险指数模型,将浙江省茶叶农业气象灾害风险划分为低风险、中风险和高风险3个等级;并在浙江省茶树栽培精细化气候区划结果基础上,生成了浙江省茶树种植农业气象灾害综合风险精细化空间分布图。结果表明:浙江省茶叶农业气象灾害综合高风险区主要位于浙西北和浙中北,中风险区主要位于浙中和浙东北,低风险区主要位于浙南;浙江省茶树种植农业气象灾害低风险适宜区主要位于浙东南和浙西南。

Abstract: Evaluating the agrometeorological disaster risk (AMDR) of tea planting can enhance the natural disaster defense ability of tea industry. Based on the statistical data of natural disasters and agricultural data of 64 observation stations in Zhejiang Province during 1971-2010, an assessment model of AMDR is developed by applying fuzzy mathematics and weighted index sum method. The AMDR of tea planting in Zhejiang is divided into three levels: low, moderate and high. By integrating the climate zoning result of tea planting into the risk assessment model, we get the refined AMDR zoning map of tea planting in Zhejiang. The high AMDR area of tea planting mainly locates in the northwest and middlenorth of Zhejiang; the moderate AMDR area includes the middle and northeast of Zhejiang; the low AMDR area mostly locates in the south of Zhejiang. The low suitable regions of tea planting mostly locate in the southeast and southwest of Zhejiang.
