目的在广泛开展广西鼠疫历史情况调查的基础上,研究自然疫源地特征、性质及状况,为制订防制策略提供科学依据。方法全面查阅历史文献,综合分析,了解鼠疫历史疫区的时间、空间分布,结合第二次全国土壤普查结果,探讨广西鼠疫自然疫源地问题。结果发现广西鼠疫历史疫区广泛分布着红壤、赤红壤和砖红壤,尤其与赤红壤关系密切。这一类土壤具有典型的热带、亚热带风化淋溶强烈的脱硅富铝化过程以及旺盛的生物物质循环过程的特征,二、三氧化物富集。结论广西鼠疫疫区特有的土壤条件有利于鼠疫菌的生成与繁衍,构成稳固的自然疫源地,进一步证明广西鼠疫作为一种古老的传染病,在长期生物进化过程中,有其自身的特点与规律,鼠疫作为一个特殊的生物现象将长期存在,鼠疫防制工作任重而道远。
Objective To investigate the characteristics, nature and status of natural foci on the basis of extensive investigation of the history of plague in Guangxi and to provide a scientific basis for the formulation of control strategies. Methods Through comprehensive review of historical documents and comprehensive analysis, we can understand the time and space distribution of the plague epidemic area, and discuss the problems of plague natural foci in Guangxi with the results of the second national soil survey. The results showed that plague area of Guangxi plague widely distributed red soil, red soil and brick red soil, especially closely related with the red soil. This type of soil has the characteristics of the typical tropical, sub-tropical weathering and leaching strong desiliconization and alumization process and the vigorous biological material cycle process, and the enrichment of trioxide. Conclusion The special soil conditions in plague endemic areas of Guangxi are favorable to the formation and multiplication of plague bacteria and constitute a solid natural source of foci. It further proves that plague in Guangxi Province, as an ancient infectious disease, has its own characteristics in long-term biological evolution And the law, plague as a special biological phenomenon will exist for a long time, the plague prevention work has a long way to go.
