Abstract: The different mixed models of Cunninghamia lanceolata and Alniphyllum fortunei and their pure forests were studied in this paper by comparing the stand structure, biomass, community character, productivity and ecological benefits. The results showed that the mixed forests of C. lanceolata and A. fortunei were a new mixed model having higher productivity and more coordinative iw mixeecific relationship. The volume and biomass of seven-year old mixed forest (3 C. lanceolata: 1 A. fortunei) increased by 7.24% and 18.22% than those of the pure stands respectively. Moreover, the mixed forests had better ecological function to ameliorate soil fertility, conserve water and improve microclimate than the pure forests. By means of Analytic Hierarchy Process, it was recognized that the mixed forest of 3 C. lanceolata with 1 A. fortunei was a practicable mixed model in southern China.
