云南具有极为复杂的地理气候。根据云南省不同的地质、地理、土壤、气候、植被特点选择样区,采集土壤样品,研究了云南不同地区、不同生态环境放线菌的生态分布与植被的关系。将云南土壤放线菌区系划分为热带区系、亚热带高原区系、滇西北高山区系和雪山区系四种类型。对云南土壤放线菌区系的特点进行了讨论。 Yunnan has a very complex geographical climate. According to different geology, geography, soil, climate and vegetation characteristics in Yunnan Province, samples were selected and soil samples were collected to study the relationship between the ecological distribution of actinomycetes and vegetation in different regions of Yunnan. The actinomyces flora of Yunnan was divided into four types: tropical zone, subtropical highland zone, northwest Yunnan high mountain zone and snow mountain zone. The characteristics of soil actinomycetes in Yunnan were discussed.
