摘　　要：根据四川省145个气象站点1981—2010年气象数据,结合全省晚熟柑橘主产区气候特点及生长情况调研结果,分析影响晚熟柑橘生长的关键气象因子,确定年平均气温、≥10℃年积温、无霜期、7月平均气温、1月平均气温、日照、降水量、海拔8个变量作为划分四川晚熟柑橘气候适宜区域的主要环境变量。应用GIS空间分析技术推算各气候要素值并采用特尔斐法确定区划指标权重,结合冬季冻害和春季高温2种主要气象灾害的风险区划,得到四川晚熟柑橘气候适宜性精细区划图。分析结果表明,四川省晚熟柑橘最适宜栽培区分布在海拔400~700 m、地势平缓的区域;晚熟柑橘可栽培区域海拔低至150~250 m,高至900~1200 m;海拔高于1200 m的高原、山地等地不适宜晚熟柑橘种植。From the climate data of 145 meteorological stations in Sichuan from 1981 to 2010,combing with the climate characteristics of the late-maturing citrus growing regions and the citrus tree status,the critical influencing factors on late-maturing citrus were analyzed.Eight environmental variables,including annual mean temperature,≥10℃accumulated temperature,frost-free period,July mean temperature,January mean temperature,sunshine hours,precipitation and altitude,were confirmed to be the climatic regionalization indices for Sichuan late-maturing citrus.Using GIS spatial interpolation,the climate elements and zoning index weight were calculated.Two meteorological disasters of late-maturing citrus during the growth period,such as the winter freezing injury and disaster elevated temperatures,were selected to conduct further zoning.The results show that the most suitable region of late-maturing citrus in Sichuan is with the altitude ranging from 400-700 m,and with gentle terrain slopes.The tolerable altitude for late-maturing citrus could be as low as 150-250 m and as high as 900-1200 m.The plateau and mountainous regions with the altitude more than 1200 m are unsuitable for late-maturing citrus growing.
