云南土壤放线菌生态分布的研究

A STUDY ON THE ECOLOGICAL DISTRIBUTION OF SOIL ACTINOMYCETE IN YUNNAN

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。

Since the end of 70' , about 4200 soil samples of collected from 22 selected areas of throughout Yunnan. The distribution and biological characteristics of actinomycetes in soil of various vegetations and climatic types were studied. The types and features of actinomycete population, and the relationship between the distribution and habitats were discussed. The population of siol actinomycete of Yunnan based on the research results can be divided into the tropical type, the subtropical plateau type, the cool temperature mountain type and the snowy mountain type.
