本文对位于中心分布区的毛白杨人工林的生物量进行了初步研究,并试图通过比较和分析不同立地类型和不同经营措施下的毛白杨林分的平均生产量,为营林生产提供科学依据。结果表明,毛白杨人工林的生物量受立地类型和经营措施的影响极大,立地类型相同经营措施不同的林分平均生产量相差三倍多,而经营措施相同立地类型不同的林分的平均生产量相差四倍还多。 In this paper, the biomass of Populus tomentosa plantation located in the central area was studied, and the comparison was made between the average production of Populus tomentosa forest under different site types and different management measures to provide a scientific basis for the forest management . The results showed that the biomass of Populus tomentosa plantation was greatly influenced by site type and management measures. The average production volume of stands with the same type of management practices differed by more than three times. However, the average of stand types with the same management practices A difference of more than four times in production.
