摘      要：This paper studies the mechanism of grassland ecosystem s soil and water conservation function on the basis of two years experiment and inspection in Jianou mountain grassland ecosystem experiment station, Fujian province. After anaIysis on the data of soil erosion and runoff coefficient, relations between eroded soil, runoff and slope gradient. we establish soil and water conservation benefit models. According to the mode1s, experiment and inspection results, some proposals have been made to decrease the area of soil erosion in Fujian mountainous areas, e. g., optimizing land use structure in mountainous areas, taking suitable measures for local condition, closing hills for grassland development, accelerating restoration and raising quality of mountain grassland ecosystem, strengthening scientific and technological input, breeding the grass species that are suitable to local physical geographic condition.
