摘　　要：本研究采用MaxEnt模型对山西省连香树的潜在分布区进行预测。结果表明,最冷季度平均温、最干月降水量和年降水量对连香树在山西省的潜在分布影响最大。连香树在山西省的潜在分布概率呈南高北低的趋势,其可能分布范围的最北界不超过太原地区。连香树在山西省的潜在最适分布区主要为吉县、大宁县、乡宁县、翼城县、绛县、闻喜县、夏县、垣曲县、沁水县、阳城县。The MaxEnt model was used to predict the potential distribution area of Cercidiphyllum japonicum in Shanxi Province.The results indicated that the average temperature in the coldest quarter precipitation in the driest month and annual precipitation had the greatest impact on the potential distribution of Cercidiphyllum japonicum in Shanxi Province.The potential distribution probability of Cercidiphyllum japonicum in Shanxi Province showed a trend of high in the south and low in the north,and its possible distribution range did not exceed the northernmost boundary of Taiyuan area.The potential optimal distribution areas for Cercidiphyllum japonicum in Shanxi Province were mainly Ji County,Daning County,Xiangning County,Yicheng County,Jiang County,Wenxi County,Xia County,Yuanqu County,Qinshui County and Yangcheng County.
