长爪沙鼠鼠疫自然疫源地是我国主要的鼠疫自然疫源地。本研究基于空间信息技术定量分析长爪沙鼠的生境特征并预测长爪沙鼠的潜在分布。其中通过长爪沙鼠国家级监测点的经纬度监测数据空间化后,得到长爪沙鼠发现点数据集;利用遥感技术获取与长爪沙鼠生活环境相关的地形地貌、气温、降水等生态环境参数;利用ArcGIS软件分析长爪沙鼠的生境特征;利用Maxent软件建模,结合3S技术获得长爪沙鼠在我国的适生区分布图。由此可见利用3S技术和Maxent模型可以进行全国范围内的长爪沙鼠适生区预测,对鼠疫自然疫源地监测工作具有积极意义。
The natural foci of gerbil plague is the main plague natural foci in China. The present study quantitatively analyzed the habitat characteristics of Mongolian gerbils and predicted the potential distribution of Mongolian gerbils based on spatial information technology. The spatial data of longitude and latitude monitoring data of Mongolian gerbil (Meriones unguiculatus) at the national monitoring points were obtained, and the dataset of Meriones unguiculatus was found. By using remote sensing technology, the ecological environment such as topography, temperature, precipitation and other environment related to the living environment of Mongolian gerbils The ArcGIS software was used to analyze the habitat characteristics of Mongolian gerbils (Meriones unguiculatus). Maxent software was used to model Meriones unguiculatus in China. Thus it can be seen that the 3S technology and Maxent model can be used to predict the fit-for-life area of Mongolian gerbils in the whole country and have a positive effect on the monitoring of plague natural foci.
