摘　　要：对 1 4年生不同密度木麻黄湿地松混交林及同一密度不同混交比例木麻黄湿地松混交林、木麻黄纯林和湿地松纯林的生物量结构进行研究 .结果表明 :不同密度混交林蓄积量和生物量随密度增大而减小 ,林分密度为 1 0 3 5株· hm-2 混交林蓄积量、生物量最大 ,分别达6 1 .47m3 · hm-2 和 1 97.6 4 t· hm-2 ,优于木麻黄、湿地松纯林 .相同密度 ( 1 0 3 5株· hm-2 )混交林随着湿地松混交比例的增大 ,生长效果越差 ,其蓄积量、生物量大小顺序为 :混交比例1∶ 1 >2∶ 3 >1∶ 4.因此建议在营造木麻黄湿地松混交林时 ,造林密度为 1 0 3 5株· hm-2 ,混交比例控制在 1∶Research on the biomass and its distribution of mixed forests of Casuarina equsetifolia×Pinus elloottii, pure 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 m\+3 and 197 64 t per hectare respectively And the growth of mixed 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 rational mixed proportion to be selected for planting mixed forests of Casuarina equsetifolia×Pinus elloottii, whose density is about 1 035 clums per hectare
