Erosion restoration measures such as,polyacrylamide (PAM),straw mulching,zonal forage (paspalum notatum),and the combination of them were used in the eroded plots of red soil rotated by peanut and wheat in southern area of Hubei Province.The water stable aggregates(more than 4.00,2.00-4.00,1.00-2.00,0.50-1.00,0.25-0.50 mm) and the content of available N,P and K in the eroded red soil was detected to reveal the effects of erosion restoration measures on aggregate stability and available nutrient.The results showed that straw mulching could significantly increase the contents of 1.00-2.00 and 2.00-4.00 mm water stable aggregate (WSA),and the increase rate was 40% for the contents of more than 0.25 mm WSA.In the straw mulching treatment,the contents of organic matter and available K separately increased 20% and 150% after planting wheat.The measures of PAM and the combination of PAM and zonal forage could increase the content of 0.50-1.00 mm WSA,and rates were 25% higher than that of the control,but they were not significant for the increase of the soil organic matter and available nutrients.The combination of zonal forage and straw mulching could significantly increase the content of more than 4.00 mm WSA by 500% compared to the control,but no obvious influences to the soil organic matter and available nutrients.The measure of straw mulching was better than the combination of straw mulching and zonal forage for increasing the content of 0.25-4.00 mm WSA.In improving the content of more than 0.25 mm WSA,the effect of the composition of PAM and zonal forage was better than the measure of zonal forage,but less than the measure of PAM for increasing the content of 0.25-1.00 mm WSA.
