| 摘 要： | 灌木生物量是衡量植被生产力的重要指标，灌木的生物量与高度、地径之间具有密切的关系．选择千烟洲试验区内的长托菝葜、牡荆、山莓、紫珠4种主要灌木，采用数学模拟的方法，以实测数据为基础，建立了灌木生物量的回归方程，并进行了检验和模拟验证，结果良好，能够用于生物量的估算。

| Abstract: | Shrub biomass is the important index of weighing the productivity of vegetation; it is an important content in vegetation ecology research. The shrub biomass closely correlates with the height and diameter size of shrubs. The research selected Smilax ferox, Vitex negundo var. cannabifolia, Rubu.s corchorifolius, Callicarpa bodinieri 4 typical shrubs from Qianyanzhou Experiment Station, established some mathematic models to estimate the shrub biomass, and evaluated the models by their correlation coefficient, significant fit, relative error and estimative error. The models are optimal equations to estimate the brush biomass. |
