自然疫源地既是一个特定的生态系统,那么,媒介生物的调查研究也就是对一定生态空间内生物群落构成的研究。生态系统和生物群落是同一层次的2个生态学问题。生物群落是多种生物种群有机结合的复合体,它强调的是生物种群之间的相互作用。而生态系统除此以外,还包括无机环境,其强调的是物质循环和能量流动。因此,就媒介生物学调查而言,需参照群落生态学的原理。由于群落的构成单位是种群,而我们研究的重点又是媒介种群,因此,在自然疫源地研究
Since natural foci are both a specific ecosystem, then the investigation of vector organisms is also a study of the composition of biomes in a certain ecological space. Ecosystems and biomes are two ecological problems at the same level. Biomes are a complex of organisms that combine organisms and emphasize the interplay between biological populations. In addition, the ecosystem includes an inorganic environment that emphasizes material circulation and energy flow. Therefore, in terms of media biology surveys, reference should be made to the principles of community ecology. As the composition of the community is a population, and our focus of research is the media population, therefore, in the study of natural foci
