| Taking the gold tailing ponds which had been closed for 14 years in Qinling Mountains as the research object, a combined electrokinetic and phytoremediation program for contaminated soil was developed. The program was designed as first screening and extracting, then calculating for optimization and interactive integrating, finally automatic evaluating. The estimated value of the program was derived from model training. The results showed that as suitable plants for growing in the tailing ponds area, Sedum alfredii, Imperata cylindrica, Lolium perenne and Dandelion were selected as hyperaccumulators. Taking Cd, Cu and Zn as eliminating objects, the relative error of evaluation efficiency and experimental efficiency of training samples were 4.7%，-3.5% and 12.4%, respectively. The evaluation efficiency of test samples were 75.6%， 47.2% and 56.5%, respectively. It could be used to guide laboratory or site soil remediation. |
