| 摘 要： | 利用川西米亚罗林区森林资源清查数据,以森林蓄积量和森林生物量之间的关系模型为基础,对川西林业局301林场的森林生物量进行了估算,并对研究地区不同林龄及森林类型的森林生物量进行了分析。研究结果表明:1)研究区域林分总生物量为3 041 229t,林分单位面积平均生物量为87.13 t/hm2,低于全国生物量及四川省生物量的平均值,主要由于占绝对优势的云、冷杉林所处立地条件差,生物量较低造成;2)林分年龄结构不合理,成、过熟林面积较大(占69%);3)水土保持林的生物量在所有森林类型中所占比例最高(占80%)。

| Abstract: | Based on the forest resource inventory data,according to the relationship model between sub-compartment volume and forest biomass,the forest biomass of 301 Forest Farm in Miyaluo forest region of west Sichun province was estimated.The forest biomass under each age class was analyzed,as well as the biomass of different forest type.The results indicated that the total biomass of the studied area was 3041229t,the average biomass was 87.13t/hm2,which is less than the average value of biomass both in national an... |
