Abstract: The absorption of Cu, Cd, Pb, F by several types of soil in different bio-climatic zones, the soil bufferring capacity to heavy metals, the effects of Cu, Cd, Pb, F on several plant nutrition elements ratio in soil solution, the effect of the ameliorants CaC03 and K2HP04 on distribution of these nutrition elements in soil-plant system, and their availibility were 3isscussed. The results indicated that absorption and bufferring capacity to Cu, Cd, Pb was strong in peat soil with high organic matter content and brown soil with high level of CaC03, but was relative weak in red soil and yellow-brown soil. The Ca concentration in soil solution increased with addition of Cu, Cd, Pb into soil, and Fe concentration increased with pollution of F. The ameliorants CaC03 and K2HP04 could change the distribution of Fe, Mn, Ca, Mg in soil-plant system. The ameliorant CaC03 could increase the plant nutrition availibility in red soil and yellow-brown soil which had lower level of CaC03,and effect of CaC03 is better than that of K2HP04 in such soil.
