摘　要：通过对木荷马尾松不同混交比例的林分生物量、蓄积量、生长状况和空间利用方面的对比研究，结果表明：一定的密度下，选择适宜的混交比例能显著提高林分生产力及空间利用率。当密度为3150株/hm2时，混交比例为1∶1的7年生林分生物量最大达m/82.90t*hm-2，蓄积量最大为V/24.73m3*hm-2，叶生物量m/14.27t*hm-2，林分生长状况良好；该处理林分，空间利用率高，生物量或蓄积量比其它模式提高30%～80%，显著提高了经济效益和生态效益，可供生产经营参考。

Abstract：Comparison on stand biomass, volume, growth condition and space utilization in the various mixed stands was conducted. The results showed that fit mixed ratio can enhance stand productivity and space utilization. Mixed stand (7a) with a density of 3150 trees per hectare and a mixed ratio of 1∶1, both stand biomass and volume were 30～80 percent higher than those of any other mixed pattern. The growth conditions of this stand was optimal, and its space utilization was high. It also made best ecomomic profits.
