A field experiment was conducted to investigate effects of wheat and faba bean intercropping on diversity of metabolic functions of rhizosphere fungal community using the Biolog micro-plate technique for analysis. Results show that compared with that in CK (single cropping) rhizosphere fungi in the intercropping treatment was obviously higher in average well color development (AWCD), and the effect was more significance with Faba bean, rather than wheat. Biolog FF plateanalysis indicates that intercropiping enhanced thecapacity of the rhizosphericfungiunder intercropped wheat and faba bean of utilizing carbonsin polymers, carbohydrates, carboxylic acids, amino acids and amines, increased their substrate richness by 29.2% and 30.3% respectively, total carbon utilization intensity 63.30% and 52.02%,respectively. Among the six categories of carbon sources, carbohydrates, carboxylic acids and amino acids, was much higher than the others in carbon utilization intensity, reaching36.66%~45.99%, 25.65%~27.70% and 16.37%~20.67%, respectively. Shannon index (H) and richnes index(S) were also found to be higher in the intercropping system than in the monocropping one. Principal component analysis demonstrates that intercropping significantly altered the rhizosphere fungal communityunder thewheat and faba bean.Therefore, it can be concluded that intercropping apparently increases metabolism intensity of the carbon sources by the rhizosphere fungi under the wheat and faba bean and significantlytheir diversity and richness, thus altering their community structure. Hence, intercropping of wheat and faba bean is an effective approach to improving micro-ecological environment of the rhizosphere of monocroppedfaba bean．
