The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

Straw returned to field played a positive role in increasing soil insect communities with the largest contribution, primarily the amounts of individuals and dominant species of macro and meso/micro soil animal, especially Neanuridae and Isotomidae animals individual amounts increased by nearly 10 times.(3) Soil nutrien had a positive correlation with soil bacteria, azotobacter, ammonifying bacteria, cellulose decomposing bacteria and denitrifying bacteria. Straw returned to field could stimulate effective microorganisms growth and population quantity in the soil. The increase of microbe community amount is 15%~44% more than that of CK.(4) Soil nutrien had a positive correlation with soil phosphatase, urease and sucrase activities, and a negative correlation with catalase.
