摘　　要：用菌丝显微图像灰度的统计分布图得到羊肚菌菌丝具有分形学的自相似性并求出其分维数。对比羊肚菌固体、液体不同培养方法下菌丝的形态及分维数,结果为分枝越多分维数越大;对比不同菌种羊肚菌和蛹虫草菌丝的分维数。说明分维数的差别对于菌丝形态特征的研究可以提供基础。This paper reports the study on the fractal characters of Morchella esculenta mycelia. Statistically analyzing the grayscale distribution image, we find the self-similarity of Morchella esculenta mycelia and evaluate its fractal dimension. The fractal dimension of the mycelia strain cultured in solid state is different from that cultured in liquid, the more the branches the higher the dimension. The dimension of  Morchella esculenta mycelia and that of Cordyceps milicaris mycelia are also varied. It reveals that fractal dimension is valid in study the morphology and characteristics of varies kinds of mycelia.
