Abstract:: In order to evaluate the quality of different wetland use patterns, by using field sampling and laboratory analysis, fourteen soil biological indices, including soil organic matter, soil microbial biomass, soil respiration, soil enzyme activity and community of soil fauna were studied in the east part of the Yellow River wetland. The results showed that soil biological indices and diversity of soil fauna community had significant differences among different land use patterns (p < 0.05). The order was in the sequence of forest wetland > humid grasslands > marsh wetland > saline-alkali wasteland. The principal components which accounted for 98.651% of cumulative variance were extracted from the raw data. Soil fertility and soil enzyme activity indices, soil fauna community index had the high load on the principal components, which can be used as biological indicators of soil characteristics in the Yellow River wetland, and these indices can reflect the changes of soil quality of wetland. The chief principal component scores indicated that forest wetland biological quality was the best and saline-alkali wasteland was the worst. The four biological indices including soil organic matter, soil microbial biomass, soil enzyme activity and diversity of soil fauna community could be used to evaluate the changes of soil quality of the Yellow River wetland.
