摘　　要：【目的】研究浙江楠在江苏地区的适宜引种区域,开展其气候适宜性分析。【方法】利用灰色关联度和主成分分析方法,结合19个生物气候指标,对浙江楠在江苏省各地市的引种气候适宜性进行综合评估。【结果】等权关联和综合评价模型的结果均支持将江苏13个地市的引种气候适宜性划分为3类,Ⅰ类为高适宜区(λ≥1.100):包括常州、无锡和苏州;Ⅱ类为中适宜引种区(0.900≤λ<1.100),包括南京、镇江、扬州、泰州和南通;Ⅲ类为低适宜引种区(λ<0.900),包括盐城、淮安、徐州、连云港和宿迁。【结论】江苏南部地区是浙江楠引种的较佳适宜地。[Purpose]To study the suitable introduction zones of Phoebe chekiangensis C. B. Shang,its suitable introduction and acclimatization zones was discussed in this study.[ Method] Based on the methods of grey correlation and principal component analysis, combining with 19 bioclimatic indices, suitable introduction and acclimatization regions of P. chekiangensis in Jiangsu Province was evaluated comprehensively.[Result]It indicated that thirteen cities of Jiangsu Province should be divided into three categories of climatic suitability in light to the equal-weight correlation degree and comprehensive evaluation model. Category Ⅰ(high suitable zone, λ≥1.100) included Changzhou,Wuxi and Suzhou;category Ⅱ(moderate suitable zone, 0.900≤λ<1.100) included Nanjing, Zhenjiang, Yangzhou, Taizhou and Nantong;category Ⅲ(low suitable zone, λ<0.900) included Yancheng,Huai’an, Xuzhou, Lianyungang and Suqian.[Conclusion]The southern part of Jiangsu Province is a better zone for the introduction of P. chekiangensis.
