农用稀土肥料对环境影响的研究

稀土肥料在农业生产中占有重要地位，但稀土在土壤中的残留、在水体中的富集以及对人体的健康危害尚未引起广泛的关注，从农用稀土的发展现状及其对土壤、水体等环境要素的负面影响出发，论述了稀土可能对长江三峡水库水体的富营养化有促进作用。由此，在使用农用稀土时，应尽可能降低和减少稀土在土壤中的残留及水体中蓄积的机会与条件。

Study on the Effect of Agricultural Rare Earth Fertilizers on Environment

Rare earth fertilizers play an important role in agriculture. However, wide attention has not been paid to the residue of rare earth fertilizers in soil and the enrichment of rare earth elements in water and their endangerment to human being. The paper discusses the possible promotion effect of rare earth on the eutrophication of water in the Three Gropes Reservior on the basis of the present development situation of rare earth in agriculture and the negative effect on essential factors of environment, such as soil and water. So, we should reduce the chance and condition for the residue in soil and the enrichment in water when rare earth is used in agriculture.
