| 摘 要： | 本文对东北东部山区红松人工林群落生物量进行了测定和研究。根据相对生长法和样方收获法分别调查和计算了乔木层、下木层、草本层、凋落层、立枯量的生物量。研究结果表明:群落总生物量为132.419t/ha, 其中乔木层106.881t/ha, 占总量的80.71%;下木层0.507t/ha, 占总量的0.38%;草本层0.292t/ha, 占总量的0.22%;凋落层20.411t/ha, 占总量的15.41%;立枯量4.328t/ha, 占总量的3.28%。通过群落生物量分布结构分析, 红松人工林急需进行抚育间伐, 调整群落产量结构, 提高群落结构的整体效应。

| Abstract: | Based on the allmetric method and quadrat-harvesting method, the standing crop of biomass of the Korean pine plantation in the east moun-tain areas of Northeast China was determined and discussed in the pres-ent paper. The results are as follows: The total biomass of Korean pine commun-ity was 132.419 t/ha, in which the biomass of tree layer, undergrowth layer, herb layer, litter and standing dead was 106.881 t/ha, 0.517 t/ha, 0.292 t/ha, 20.411 t/ha and 4.328 t/ha respectively, the percentage of each component to the total biomass was 80.71%, 0.38%, 0.22%, 15.41% and 3.28% respectively Based on the analysis of distrbution structure of the biomass in korean pine community, tending felling must be conducted urgentyly in Korean pine:plantation so as to regulate the structure of production and improve the integrate effect of the community. |
