摘要: 应用分形理论(Fractal theory)中的计盒维数(Box-counting dimension)对三江平原小叶章(Deyeuxia angustifolia)种群分布格局特征进行了研究。结果表明:三江平原小叶章种群分布格局具有分形特征。其计盒维数5~9月分别为1.524、1.769、1.711、1.615、1.701,表明其占据空间能力较强。季节动态自5月始至6月达到极大值,而后逐渐下降,至9月略有回升。这与小叶章的生长发育规律相一致。

Abstract: The distribution pattern of D. Angustifolia in the Sanjiang plain has been described by using the box dimension and information dimension of fractal theory. The result reveals that:There was fractal feature. The box dimension respectively was 1.524、1.769、1.711、1.615 and 1.701 from May to September. Powerfully occupy space has been shown. Seasonal dynamic of box dimensions reached their maximum values beginning May to June then fell down. They were gone up again in September. This was accordance with the growth rhythm of D. Angustifolia population.

Key words: Deyeuxia angustifolia population, distribution pattern, box dimension, ecological unoccupation dimension
