摘要
采集高黎贡山不同海拔高度土壤242份,从中分离鉴定出3属23种捕食线虫真菌,包括节丛孢属(Arthrobotrys),小掘氏孢属(Drechslerella)和小隔指孢属(Dactylellina)。随海拔升高,捕食线虫真菌多样性及检出率逐渐递减,在海拔1410—2123 m的低山地带捕食线虫真菌最为丰富,Arthrobotrys oligospora和Arthrobotrys musiformis为优势种,总检出率分别为44.39%和15.61%,多样性指数分别为1.93和2.19。在海拔2200—3484 m,A.musiformis为优势种,总检出率是16.62%。所分离到的捕食线虫真菌中,产黏性菌网的菌种占优势(78.26%),为高黎贡山捕食线虫真菌的优势种群。
Twenty three species nematode-trapping fungi belonged to three genera （Arthrobotrys, Drechslerella and Dactylellina） were isolated and identified from 242 samples collected from the different altitude Gaoligong Mountain. The results showed that the fungal diversity and detection rate decreased with the increasing of the altitude, the richest nematode-trapping fungi distributed at altitude of 1410-2123 m, and its dominant species were Arthrobotrys oligospora and .4. musiformis; the total detection rates were 44.39% and 15.61% and diversity indexes were 1.93 and 2.19 respectively. A. musiformis was dominant species at altitude of 2200-3484 m; its total detection rate was 16.62%. The species forming adhesive networks was dominant （78.26%） in Gaoligong Mountain.
