The biomass,coverage and height of Disranopteris dichotoma,as well as topography,soil nutrients and soil erosion degree in Changting County,Fujian Province,were investigated using quadrat methods.The differences of the biomass were evident in different slope directions.The total biomass for the quadrats on east slope was with the maximum of 1 967.65g/m² and for the quadrats on south slope,with the minimum of 1 230.28g/m².The coverage and height decreased with increased slope position.The total biomass,coverage and height were positively correlated with soil organic matter and total nitrogen.Soil erosion degree was significantly negatively correlated with the biomass,coverage and height.The Dicranopteris dichotoma growth was apparently influenced by soil erosion degree,soil organic matter and total nitrogen.Dicranopteris dichotoma plays some important roles in controlling soil and water loss and therefore,it can be used as pioneer vegetation in soil and water conservation and ecological restoration of the study area.
