:通过四川盆地西缘山地峨边林区的峨眉冷杉 ( Abies fabri)人工林生物量和生产力进行的测定和研究 ,据调查数据 ,应用“相对生长法则”建立了估测峨眉冷杉人工林乔木层各器官生物量的回归方程。结果表明 :35年～ 36年生峨眉冷杉人工林分生物量平均为1 95.70 4 t· hm- 2 ,净初级生产力为 9360 .4 kg· hm- 2· a- 1 ,其中乔木层生物量为 1 73.1 0 0t· hm- 2 ,净初级生产力为 84 74 .6kg· hm- 2 · a- 1 ,乔木层净同化率为 36.1 g· m- 2 · a- 1 ,叶面积指数为 2 3.5m2 · m- 2 ;林内灌木层、草本层、苔藓层和枯落物层生物量分别占林分生物量的 0 .3%、0 .1 %、0 .2 %和 1 1 .1 %。同时测定和分析了峨眉冷杉人工林分的产量结构
: Based on the survey data and the “relative growth rule”, the plantation and plant biomass of Abies fabri plantation in the mountainous Ebian forest area in the west edge of Sichuan Basin were estimated. Regression equation of biomass of each organ. The results showed that the average biomass of Abies fabri forests at the age of 35 to 36 years was 1 95.70 4 t · hm-2, and the net primary productivity was 9360.4 kg · hm-2 · a-1, 73.1 0 0 t · hm-2, the net primary productivity was 84 74.6 kg · hm-2 · a-1, the net assimilation rate was 36.1 g · m-2 · a-1 and the leaf area index was 23.5 m 2 · m-2. The biomass of forest shrub layer, herb layer, moss layer and litter layer accounted for 0.3%, 0.1%, 0.2% and 11.1% of stand biomass, respectively. At the same time, the yield structure of Fir plantation in Emei Mountain was determined and analyzed
