Abstract

Based on the comment of three different sites—TB (top part of the bank), SB (slope part of the bank) and  LB( low part of the bank) of Tongyu Canal bank in Ganyu county of Jiangsu Province, an experiment with trees introduction and g interplanting e was conducted. As the combination of trees and crops, various cubic sub-models on different sites (TB, SB and LB) was set up. Analysis of growth annual economic benefits produced by different tree on same site  compared with each other or by those same trees on different sites was carried out, the optimal trees and crops fit for TB, SB and LB were selected, furthermore, in the view of synthetic benefits of economic, ecology and society, so the optimal model is designed as following , TB: Tooma sinensis Roem. + wheat + bean, SB: polar I-69 +wheat + bean and LB: polar I-105+Salix purpurea L. Its annual profit will in crease 40.9% than that of model(TB, SB and LB: polar I-69 +wheat + bean).
