Abstract: Objective To analyze the climatic and environmental factors that affect the distribution of Dermacentor silvarum in China and the potentially suitable habitats of D. silvarum, and to project the impact of climate changes on the distribution of D. silvarum in China. Methods The geographical distribution of D. silvarum in China was searched, and the coordinate information of distribution points was extracted.Maximum entropy model was used to project the potentially suitable habitats of D. silvarum in China. Results Among the climatic and environmental factors, altitude (21.6%), precipitation of coldest quarter (16.7%), mean temperature of driest quarter (15.4%), and annual mean temperature (12.3%) had great influence on the distribution of D. silvarum in China. D. silvarum was mainly distributed in the north of China, especially in Inner Mongolia Autonomous Region and northeast China. Under the representative concentration pathway 4.5 scenario, the suitable area of D. silvarum in China will increase by 104 thousand square kilometers by 2070, and the new suitable areas are mainly located in Hunan, Qinghai, Jiangxi, and Zhejiang provinces. Conclusion Altitude may be the main factors affecting the distribution of D. silvarum, and the distribution range of D. silvarum will be expanded in future climate scenarioes.

摘要: 目的 分析影响森林革蜱分布的气候环境因子及其在我国的潜在适生区,并预估气候变化对我国森林革蜱分布的影响。方法 检索森林革蜱在我国的地理分布相关文献,提取分布点坐标信息,采用最大熵模型(maximum entropy model,MaxEnt)对我国森林革蜱潜在适生区进行预估。结果 对我国森林革蜱分布影响较大的气候环境因子中依次为海拔(贡献率为21.6%)、最冷季降水量(16.7%)、最干季平均温度(15.4%)、年平均温度(12.3%);森林革蜱主要分布于我国北方,尤其是内蒙古自治区和中国东北地区;在典型路径浓度(RCP)4.5气候情景下,2070年我国森林革蜱适生区面积将增加10.4×104 km2,新增适生区主要分布于湖南、青海、江西和浙江省。结论 海拔可能是影响森林革蜱分布的主要因素,未来气候条件下森林革蜱的分布范围将会扩大。
