自然疫源地作为一个特定的生态系,其中每一个组分都是互相关联的。从生态学观点来分析,媒介节肌动物不仅本身作为某一疫源地生境中的一员,而且又是微生物藉以生存繁衍的环境,这就是媒介生物在疫源地中特殊的地位。因此,要弄明白媒介生物在自然疫源地中的地位,不仅要从宏观的生态学关系中去探讨,还应从微生态学方面去研究。所以,必需了解生态学与微生态学之间的关系,及与自然 Natural foci as a specific ecosystem, each of which components are interrelated. From an ecological point of view, it is not only a member of the media, but also the environment in which microbes survive and multiply. This is the special status of vector organisms in the foci of endemic areas. Therefore, to understand the status of vector organisms in natural foci, we should not only explore the relationship between macroscopic ecology, but also study the micro-ecology. Therefore, we must understand the relationship between ecology and micro-ecology, and with nature
