Evolution of the Suitable Introduction and Acclimatization Zones of Phoebe chekiangensis in Jiangsu Province Based on Grey Correlation Method

PurposeTo study the suitable introduction zones of Phoebe chekiangensis C. B. Shang, its suitable introduction and acclimatization zones was discussed in this study.

MethodBased 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.

ResultIt 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 \geqslant 1.100) included Changzhou, Wuxi and Suzhou; category Ⅱ (moderate suitable zone, 0.900 \leqslant 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.

ConclusionThe southern part of Jiangsu Province is a better zone for the introduction of P. chekiangensis.
