APPLICATION OF THE FUZZY GRAPH THEORY IN THE VEGETATIONAL REGIONALISM OF SHANXI PROVINCE
模糊图论在山西植被区划中的应用

In this paper, the maximal-tree method of the fuzzy graph theory isapplied to the numerical classfication research of vegetational regionalismof Shanxi Province, which is divided into 2 vegetational zones, 6 vegeta-tional regions, 17 vegetational plots. Compared with fuzzy clustering an-alysis and other methods which are used in plant synecology, the maxi-mal-tree method of the fuzzy graph theory produces tree graph from si-milar coefficient matrices directly so that it avoids the comples compou-nd calculation of similar coefficient matrices. However, the result is notonly more audio-visual, but also more satisfactory, Thus we deem it su-itable to apply the fuzzy graph theory to vetetational regionalism.
