Dempster-Shafer(D-S) method has been used widely in all kinds of data fusion system,but it has difficulty in dealing with combining evidences with high degree of conflict.In order to solve problem,this paper proposed a new method based on local conflict distribution strategy.According to Jousselme's distance,the credibility of each evidence and the weighted average evidence were obtained.Then every focal elements' absolute distance was got,according to absolute distance the credibility of each focal element were obtained.Finally,the results of numerical examples show that the proposed method improves the reliability and rationality of the evidence combination results.
