摘　　要：高生物量反映了林木保存量和生长量的综合信息,是评价飞播造林成效和效益的重要指标。采用林地油松保存量与平均苗高乘积为高生物量指标,利用ANOVA-LSD均值检验法和模型分析法,研究了施用RPA的14年生飞播油松林和对照油松林高生物量差异及其时序动态。结果表明:采用RPA拌种进行飞播造林,不仅能提高飞播油松林分的高生物量,而且能消弱油松高生物量生长的抑制周期。其高生物量可用Exponential-模型和Logistic-模型预测和分析。Biomass reflects the integrated information of preserving quantity and growth increment of trees, it is an important index for the evaluation of the effectiveness and benefits of aerial seeding. By using pre- serving quantity and average height of as the height-biomass indicators,and using the ANOVA-LSD mean value test method and the model analysis method, the effectiveness and temporal dynamics of 14-year-old Pinus tabulaeformis plantations that were aerial seeded and treated by RPA were investigated. The results indicated that the application of RPA could not only improve the forest height-biomass,but also reduce the the inhibition cycles of the biomass growth. The height-biomass could be estimated by exponential-model and the Logistic-model.
