Water property of runoff in seven planting patterns was conducted in runoff area of Gezigou watershed,Yubei,Chongqing.The results show that: compared with the un-harnessed area,the comprehensive planting patterns in middle and foot slope runoff sections with high vegetation cover are harnessed effectively,the signal planting patterns in the middle slope but comprehensive planting patterns in the foot slope runoff sections with lower vegetation cover are worst.The content of Cd in the comprehensive planting patterns in the foot slope runoff section with oranges planted recently and the content of Pb in the signal planting patterns in the middle slope but comprehensive planting patterns in the foot slope runoff sections with lower vegetation cover are the highest.The contamination degree in the comprehensive planting patterns in the foot slope runoff section with oranges planted recently is the least,but the most contamination degree appealed in the comprehensive planting patterns in middle and foot slope runoff sections with high vegetation cover.There are remarkably correlation between TN,TP,Pb,Cd,COD and sedimentation in surface runoff;there are also remarkably correlation between the content of COD and TP,sedimentation,moreover the content of TN is the principal factor affected COD in surface runoff.
