摘　　要：为了解烟草根结线虫衰退土中食线虫真菌的资源分布情况，对贵州省有根结线虫衰退现象的烤烟地进行了调查、鉴定。结果表明：烟草根结线虫衰退土中食线虫真菌的分布极富，有７个属，３０个种；衰退土不同其分布情况和富集种也不同；衰退土中食线虫真菌的垂直分布有一定特点，以０～１０ｃｍ深土层中分布最多，３０ｃｍ以下最少。For study on the resource distribution of nematophagous fungi, the investigation and identification of the fungi in the suppressive soil caused by tobacco root knot nematode was conducted and the results showed that nematophagous fungi is abundant in the suppressive soil and it is classified as 7 genus and 30 species. The distribution and dominant species vary from different suppressive soil type. The vertical distribution in suppressive soil was characterized with most fungi centralizing within 0～10cm depth and the least under 30cm depth.
