摘　　要：[目的]制作福州市越冬茬番茄种植精细化气候适宜性区划图。[方法]基于福建省67个国家气象观测站1981—2018年气候资料和1991—2018年冬季寒冻害灾情资料,采用冬季(12月月至翌年2月)≥10℃活动积温、平均气温、日照时数作为越冬茬番茄的气候资源指标,选取80%保证率的冬季极端低温、冬季平均日最低气温构建越冬茬番茄的寒冻害风险指标。采用统计方法建立区划指标的地理模型,应用ArcGIS的空间分析和多层复合方法,对福州市越冬茬番茄种植气候适宜性进行区域划分。[结果]福州市越冬茬番茄种植气候适宜区主要分布于长乐、福清的低平区域;次适宜区为闽侯、闽清沿闽江两岸低平区域和罗源、连江的部分区域;不适宜区主要分布于晋安、闽侯、连江、罗源、闽清、永泰、福清、长乐的中高海拔山区。[结论]该研究可为规划福州市设施越冬茬番茄的生产布局提供参考。[Objective]The aim was to make the refined climatic suitability zoning map of overwintering tomato cultivation in Fuzhou city.[Method]Based on the climate data of 67 national meteorological observation stations in Fujian province from 1981 to 2018 and the data of winter freezing disaster from 1991 to 2018,the active accumulated temperature of≥10℃in winter(December to February of the following year),average temperature and sunshine hours were used as the climatic resource indicators of overwintering tomatoes.The extreme low temperature in winter with 80%guarantee rate and the average daily minimum temperature in winter were selected to construct the cold and freezing risk index of overwintering tomatoes.The geographical model of zoning index was established by statistical method,and the climate suitability of overwintering tomato in Fuzhou was divided by ArcGIS spatial analysis and multi-layer composite method.[Result]The climate suitable areas for overwintering tomato cultivation in Fuzhou were mainly distributed in the low flat areas of Changle and Fuqing.The sub-suitable areas were the low-level areas along the Minjiang River in Minhou and Minqing,and some areas of Luoyuan and Lianjiang.The unsuitable areas were mainly distributed in the middle and high altitude mountainous areas of Jin’an,Minhou,Lianjiang,Luoyuan,Minqing,Yongtai,Fuqing and Changle.[Conclusion]This study can provide reference for planning the production layout of overwintering tomato in Fuzhou.
