%X Plant growth and species compositions are affected by the soil properties in semiarid grassland.Therefore studying the relationships between plant distributions and soil nutrient characteristics are important to understand the spatial patterns and process of plants in ecosystems of semiarid grassland.In this paper we use soil nutrient field analysis(SNFA)method to study the relations of plant overground biomass(POB)and summed dominance ratio(SDR)with 13 soil factors,i.e.,organic materials,total N,total P,to...
