| 摘 要： | 根系形态结构是影响植物生长的重要因素。应用分形理论推导出根系长度与粗度（直径）的分形维数的计算方程，初步研究了苜蓿（Medicago sativa L.）根系形态特征。结果表明：推导出的分形维数计算公式可以应用于苜蓿根系结构的研究，并且分形维数的大小能够表征苜蓿根系形态结构特性。

| Abstract: | Root morphological structure is an important factor to affect the growth of plant. Using fractal theory deduced the calculation equation of fractal dimension of root's length and diameter, and the characters of root morphological structure of Medicago sativa L were studied. The results showed that the calculation equation of fractal dimension could apply to the study of root structure of Medicago sativa L, and the value of fractal dimension could indicate the characters of root morphological structure of Medicago sativa L. |
