The myxobacteria are screened from 35 samples included water, mud, rabbit dung, goat dung, rotten wood,weathered rock,from different prefectures and counties of Chengdu by rabbit dung pellets inducing method, VY/4 carbendazim agar culture inducing method and mineral salt agar culture inducing method. Forty two myxobacteria strains are isolated from 7 genera,which belong to Myxococcus,Chondromyces ,Angiococcus, Archangium, Melittangium , Sorangium and Stigmatella , and are detected by their physiological , biological and morphological characteristics. The statistical analysis of population distribution and diversity are done by comparing the collection sites of samples,the variety of samples and the ecological environment of collection sites,it is found that there are plentful quantity and genera of myxobacteria in Chengdu region Especially,there are 7 myxobacteria strains in 5 genera from the river water samples of Huanglong ancient town. The study also shows that ratio of purification in the sample from tourist landscape area are the highest among the collection sites,and followed by the samples of forest,grassland and fruit gardens. The ratio of purification of myxobacteria in the tourist landscape area and resource diversity are higher than that of other invironment.
