By using the principles and methods of fractal geometry theory, the relationship between above ground biomass and plant length or sheath height of Carex lasiocarpa population was studied. The results showed that there was a good static fractal relationship between them, and the resulted fractal dimension was an efficient description of the accumulation of above ground biomass in each organ. The dynamic fractal relationship showed that during the whole growing season, the increase of above ground biomass had a self-similarity, being a fractal growth process, and the pattern of its increase was the fractal dimension D. Based on these results, a fractal growth model of Carex lasiocarpa population was established, which regarded the bigger grass as the result of the amplification of seedling growth.
运用分形几何理论的原理和方法，研究了毛果苔草种群地上生物量与株长或叶鞘高度之间的关系。结果表明，它们之间存在良好的静态分形关系，所得分形维数是对各器官地上生物量积累的有效描述。动态分形关系表明，在整个生长季，地上生物量的增加具有自相似性，是一个分形生长过程，其增加模式为分形维数D。基于这些结果，建立了毛果苔草种群的分形生长模型，该模型将较大的植株视为幼苗生长放大的结果。
