摘要: 目的 了解青藏高原地区西藏革蜱的潜在地理分布,探究影响其潜在地理分布的主要因素,为西藏革蜱监测和相关蜱传疾病的预防控制提供科学依据。方法 基于西藏革蜱分布位点、27种环境变量、当前时期1970-2000年与典型浓度路径(RCP)4.5情景下未来4个时期(2030s、2050s、2070s和2090s)的数据,利用MaxEnt模型与ArcGIS 10.8软件对西藏革蜱的青藏高原潜在地理分布进行预测预估与可视化展示。结果 当前西藏革蜱主要分布于青海省西部、四川省西北部、西藏东部地区与西藏拉萨市周边区域,零星分布于西藏阿里地区,适生区面积占青藏高原总面积15.66%。影响其分布的主要因素为年平均温度、最干季节平均温度、人类足迹指数与海拔。未来时期,高适生区面积均有不同程度的减少,但总适生区面积均有增加。西藏革蜱在未来气候变化情景下呈现向西迁移的趋势。结论 青藏高原大部分地区可能存在西藏革蜱,且受环境因素与人类活动因素影响,分布范围较广,潜在危害较大,尤其在人类活动密集且气温偏低的地区,西藏革蜱出现的概率更高。

Abstract: Objective To investigate the potential geographic distribution of Dermacentor everestianus in the Qinghai-Tibet Plateau region and explore the main factors influencing its potential geographic distribution, so as to provide a scientific basis for the tick surveillance and prevention and control of related tick-borne diseases in China. Methods Based on the distribution sites of D. everestianus, 27 environmental variables, and the data of current periods (1970-2000) and four future periods (2030s, 2050s, 2070s, and 2090s) under representative concentration pathway (RCP) 4.5 scenario, the MaxEnt model and ArcGIS 10.8 software were used to predict, project, and visualize the potential geographic distribution of D. everestianus in the Qinghai-Tibet Plateau. Results Currently, D. everestianus is mainly distributed in western Qinghai Province, northwest Sichuan Province, eastern Xizang Autonomous Region, and surrounding areas of Lhasa City, with sporadic distribution in the Ngari Prefecture of Tibet. The suitable habitat area covers approximately 15.66% of the Qinghai-Tibet Plateau. The main factors influencing the distribution include annual mean temperature, mean temperature of the driest season, human footprint index, and altitude. In future periods, the area of highly suitable habitats is expected to decrease to varying extents, while the total area of suitable habitats is projected to increase. Under future climate conditions, D. everestianus is expected to migrate westward. Conclusions D. everestianus may be present in most areas of the Qinghai-Tibet Plateau, with a broad distribution wide due to the influence of environmental factors and human activities, and posing the greater potential harm. Especially in areas with dense human activities and low temperatures, the probability of the occurrence of D. everestianus is higher.
