<p>In this study, we developed the analysis method of vegetation distributions in terms of prevention of the fire spreading through applying a fire-spreading model. With the fire-spreading model, we analyzed the spatial relationship between vegetation distributions and buildings in the two cases: one meant ordinary situation, the other meant current vegetation distribution was removed hypothetically. The difference between the numbers of buildings burnt in the two cases was defined as the vegetation role in preventing the fire spreading. As a result, it was shown that the differences might be the spatial information that could be useful for the estimation of the vegetation role in terms of prevention of the fire spreading. Through the comparison between the analysis result and the result of field survey, the proposed method seemed to be valid for evaluation of vegetation functions for prevention of the fire spreading in an urban area.</p>
