塔克拉玛干沙漠梭梭地上结构和生物量的自相似模型

The Self-Similarity Models between Shoot Structure and Biomass of Haloxylon Ammodendron in the Taklamagan Desert, China

应用分形自相似原理研究了极端干旱的塔克拉玛干沙漠公路两旁及油田工作区梭梭(Haloxylon ammodendron)的地上结构.研究发现,梭梭枝长、基径和冠幅与植株整个地上部分结构之间存在很好的自相似关系、本文基于自相似原理建立了以分枝推测整株生物量的简洁实用的数学模型.

The shoot structure of the Haloxylon ammodendron along the highway and in the oil field in the Taklamagan Desert is studied by using the fractal theory. Results show that there are good statistical self-similarity relationships between the length of branch, basal stem diameter, and crown amplitude and shoot mass of Haloxylon ammodendron. We construct a model for estimating shoot biomass from its branch, based on the self-similarity theory in this paper.
