To study the ecological and economic benefits on Eucalyptus and medical plant intercropping mode, and choose a good pattern both have good ecological benefits and economic benefits. This paper studied on tree and medical plant intercropping mode(including Euonymus fortunei and Lonicera japonica and Abrus cantoniensis) of Eucalyptus plantation for 5 years, which compared with pure forest of eucalyptus mode. The results showed:(1) Compared with CK patterns, A1 and A3 of the six kinds of models had good ecological benefits. The amount of litterfall increased by 19.5 percent and 30 percent, The volum increased by 25.18m3/hm2 and. 36.39m3/hm2, Forest air and soil temperature decreased obviously, the humidity was improved, soil porosity and the maximum water content increased Obviously, the organic matter and available N, P, K content increased by more than 3.5 percent, the Surface runoff reduced by more than 9.2 percent.(2) The A3 and B3 model has good economic benefits, the net yield of medicine was 94.1 percent and 185.16 percent, It's total net yield is 102.2 percent and 86.5 percent of the CK mode.(3)the A3 mode both have good ecological benefit and economic benefit,and it is suitable for popularization and application.
