摘要: 应用分形几何学(Fractal geometry)的原理和方法对羊草(Aneurolepidium chinense)种群地上部生物量与株高的关系进行了研究.结果表明.羊草种群的地上部生物量与株高存在很好的静态分形关系,所得分形维数是对地上部生物量在各器官中积累规律(生物量配比)的表征;羊草种群地上部生物量与株高的动态分形关系表明在整个生长季内该种群地上部生物量的增长具有自相似性.是一个分形生长过程,增长规律为分形维数值D;在此基础上建立了羊草种群的分形生长模式.认为成熟植株可以看作是其幼苗经生长放大过程而得到的.

Abstract: By the use of the principles and methods of fractal geometry, the relationship between aboveground biomass and plant height of Aneurolepidium chinense population was studied. The results show that there is a good static fractal relationship between them, and the resulted fractal dimension is an efficient description of foe accumulation of aboveground biomass in each organ. Their dynamic fractal relationship shows that during the whole growing season, the increase of aboveground biomass has a selfsimilarily, being a fractal growth process, and the pattern of this increase is the fractal dimension D. Baed on these results, a fractal growth model of AAneurolepidium chinense population is established, which regards the mature grass as the result of the amplification of seedling growth.
