【摘要】 利用 GIS空间统计工具分析了中国鼠疫疫源地的分布状况 ,结果表明我国鼠疫疫源地明显呈现南、北两个不连续的带状分布 ,北方鼠疫疫源地类型多 ,面积大 ;南方鼠疫疫源地类型少 ,面积小 ,并计算出我国鼠疫疫源地的面积为 1 2 6万 km2 。在此基础上 ,利用我国人间鼠疫流行资料 ,分析了鼠疫空间分布规律。两者的对比表明 ,鼠疫病区面积在鼠疫疫源地基础上扩大一倍。由于受自然条件、人类社会经济因素和鼠疫流行规律影响 ,南方鼠疫病区在鼠疫疫源地的基础上扩展范围比北方明显。最后作者利用历史病情资料从 1 840～ 1 990按十年段 ,重建了1 50年来中国鼠疫流行扩散简史。更多还原

【Abstract】 The spatial distribution of plague foci and plague affected areas in China are studied by GIS spatial analysis methods. The results show that there are two uncontinuous plague foci belts in South and North China. The total plague foci cover an area of about 126 km 2, but the plague affected areas are doubled. Due to the impact of natural environment and human socio economic activities, the ratio of the plague foci covered area to the plague affected areas is significantly higher in South China than in North China. Then using the historical data of plague and 10 year interval data, the 150 years spread history of the plague epidemics in China is rebuilt.更多还原
