Abstract：Research on the biomass and its distribution of m ixed forests of Casuarina equsetifolia×Pinus elloottii, p u re Casuarina equsetifolia forest and pure Pinus elloottii forest are presented in this paper, by using the method of“average stand and tree”and“quadrate harvesting”.The results show that the total volume and biomass of mixed forests whose density is 1 035 culms per hectare, are highest compared with other mixed forests and pure forests, which are 61.47 m³ and 197.64 t per hectare respectively. And the growth of m ixed forests decrease with the increase of mixed proportion in the same density, the order is 1∶1＞2∶3＞1∶4 in volume and biomass. So, pattern of 1∶1 is the r ational mixed proportion to be selected for planting mixed forests of Casuarina equsetifolia×Pinus elloottii, whose density is about 1 035 clums per hectare.
