对自然疫源地学说的探讨

The Investigation Over the Theory of Natural Focus

本文提出了在自然疫源地的调研中要重视应用《综合自然地理学》的新成果，建议利用《中国综合自然区划》中的自然区反映景观级别划分疫区，参考＂土地类型＂等资料和运用景观学的综合指标进行＂相＂和＂相组＂的划分来反映疫核。就进化理论的新观点指出对自然疫源性的病毒类疾病中新的地理株、生理株乃至真正新种在短期内形成的可能性应予关注，还对学说中主体的认识水平及＂自然＂的概念提出了讨论。

In the article the author put forward that in the investigation on natural focuses great attention should be paid to the application of new findings of integrated physical geography. There it was suggested that natural regions of Chinese integrated physicogeographical regionalization be applied as landscape grades for the division of epidemic areas,and materials of land types referred to.‘Facies'and‘facies groups'should be divided according to complex riorms of land-scape science in order to reflect the inferior epidemic centers.Then,based on the grades of epidemic areas,their types weresummed up,i.e.scientific classification.According to new ideas of the theory of evolution,the author pointed out that new geographical,physiological strains of virual diseases of natural focuses and even the possibility of a genuine new species formed in a short time should be followed with interest.Researchers should face realistic landscapes and work hard in practical researches.The author have analysed the proper meaning of E.H.Pavlovski's'Complex ecology',pointing the ecological significance of ceosystem,considering that natural focus involves a problem of many subjects,many research-levels,and many methods,therefore,need not understand ecological actions in isolation.
