摘　　要：长角血蜱作为一种专性吸血外寄生虫,是很多病原的重要传播媒介。基于长角血蜱的分布数据和环境数据,利用最大熵(MaxEnt)模型对长角血蜱在中国大陆地区的潜在地理分布进行预测,评估不同环境因素对长角血蜱分布的影响。结果显示,长角血蜱在中国的适生区面积为363.97×104 km 2,约占全国陆地总面积的37.78%。长角血蜱适宜生存地区主要位于我国东北部、华北、南部沿海地区以及西藏的南部。植被覆盖度、降水、人口密度、温度和动物密度是影响长角血蜱地理分布的重要环境因素。研究结果可为长角血蜱监测工作和蜱传疾病的预防控制提供参考。As an obligate blood-sucking ectoparasite,Haemaphysalis longhornis is an important transmission vector of many pathogens.Based on the distribution data and environmental data of Haemaphysalis longhornis,the MaxEnt model was applied to predict the potential geographic distribution of Haemaphysalis longhornis in China's Mainland,assessing the impact of different environmental factors on the distribution of Haemaphysalis longhornis.The results showed that the suitable area of Haemaphysalis longhornis in China is 363.97×104 km 2,which accounts for about 37.78%of the total land area of China.The areas suitable for survival are mainly located in the northeastern,northern and southern coastal areas of China and the southern part of Tibet.Vegetation coverage,precipitation,population density,temperature and animal density are important environmental factors that affect the geographical distribution of Haemaphysalis longhornis.This study can provide references for the monitoring of Haemaphysalis longhornis and the prevention and control of tick-borne diseases.
