Advance in the Research on Soil Environmental Quality Standard in China and Its Prospect

HE Zhong-jun~1,LIANG She-wang~2,HONG Chang-qing~1,XION Jun-fen~1 ( 1. College of Resource and Environmental, Yunnan Agricultural University, Kunming 650201, China 2. Primary and Middle School of Yunnan Agricultural University, Kunming 650201, China )  
This paper summarized the main methods for formulating soil environmental quality standard(SEQS), which included geochemical method, eco-environmental effect method and poisonous critical value method of available heavy metal, of which the advantage and shortage were also discussed. The existing problems of current SEQS in China were pointed out and the formulating principle of first and second class standard, the determination of polluted matter types and their critical value in SEQS were further discussed. Proposals were given to the formulation of SEQS, which included that the regional feature should be considered, the items of organic polluted matter should be changed and added, and the available form of heavy metal should be used as evaluation index, as well as the critical value of lead should be decreased.
