Four different methods are used to estimate the nutrient utlization efficiency of grassland,fernland and shrubland in Hong Kong. The results show that nutrient utilization efficiency calculated by Hirose ( 1975 )and Vitousek ( 1982 )methods are in the same order for three communities,i.e. ,grassland > fernland>shrubland.Compared with other studies on tropical forest,it is found that the nutrient utilization efficiency of grassland fernland and shrubland is greater than that of forest land.
