Grasslands can be the important Riparian buffer strips to play a significant role in ameliorating rivers' water quality and ecological functions. Selecting Festuca arundinacea,Trifolium repens and Cynodon Dactylon L.Pers as experimental plants,This study tested the soil physical and chemical indices,plant root-system indices as well as soil fauna indices in each sample plot to analyze the impacts by different grasslands on such ecological functions of riparian buffer strips for water and soil conservation and biodiversity maintenance. Results showed that the grassland of three types could all improve the soil quality and biodiversity maintenance compared to the vegetable field and wasteland nearby. Festuca arundinacea excelled in soil conservation and,Trifolium repens had advantages in diversity maintenance of soil fauna,while Cynodon Dactylon L.Pers had obvious abilities to adjust soil's physical and chemical quality.
