摘　要：通過對木荷馬尾松不同混交比例的林分生物量、蓄積量、生長狀況和空間利用方面的對比研究，結果表明：一定的密度下，選擇適宜的混交比例能顯著提高林分生產(chǎn)力及空間利用率。當密度為3150株/hm2時，混交比例為1∶1的7年生林分生物量最大達m/82.90t*hm-2，蓄積量最大為V/24.73m3*hm-2，葉生物量m/14.27t*hm-2，林分生長狀況良好；該處理林分，空間利用率高，生物量或蓄積量比其它模式提高30%～80%，顯著提高了經(jīng)濟效益和生態(tài)效益，可供生產(chǎn)經(jīng)營參考。

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.
