%X In this paper,nutrient element contents in soil and plants in thd Trifolium pratense and Dactylis glomerata artificial grassland in the Hongchiba area,eastern part of Sichuan province were analysed.The major results are as follows: 1)The contents of Fe,K and Mg were high,the contents of Na,Ca,N,Mn and P were low,the contents of S,Zn,B,Cu and Mo were very small. 2) According to enrichment parameter of elements,Ca and S were heavy leached elements,K,P,Mg,Zn and Na were moderately leached elements,Fe and Cu were lightly leached elements and Mn is an enriched element in the soil. 3) According to biological absorption series of elements, T.pratense was N Ca type plant, D.glomerata was N K P type. 4) Biological absorption coefficients of Ca,S and P were high,those of Na and Fe were low,those of the other 7 elements were in between.
