With improvement of soil structure

soil aeration

soil nutrient status in eroded red soil

amounts of annual runoff

land loss and erosion module decreased sharply

soil microbe

soil biomass

soil respiration and soil enzymatic activities had been increased greatly

also their distribution was similar to that of soil nutrient content and soil water stable aggregates in these observed district. The results indicated that with reclamation of eroded red soil

the process of soil organic remnant decomposition and humus compound had been strengthened

soil fertility had continually been recovered. Effects of different utilization patterns on soil microbe and enzymatic activities were compared. Woodlands were better than grasslands

broadleaf forest was better than conifer forest. With the time of reclamation prolonged

effects of reclamation were much more obvious.
