证据冲突是多证据融合中各种合成方法的主要制约问题，本文引入K—L信息距离函数描述证据间的冲突特征，通过构造距离矩阵定义独立证据在整个系统的冲突程度，实现对证据冲突的系统化识别．模拟实验表明：K—L信息距离的有效冲突识别，能完善D—s理论合成规则的应用约束，对正常冲突证据合成得到优化收敛结果，对高度冲突隔离证据的特征分析提取价值信息．
證據遲突是多證據融閤中各種閤成方法的主要製約問題，本文引入K—L信息距離函數描述證據間的遲突特徵，通過構造距離矩陣定義獨立證據在整箇繫統的遲突程度，實現對證據遲突的繫統化識彆．模擬實驗錶明：K—L信息距離的有效遲突識彆，能完善D—s理論閤成規則的應用約束，對正常遲突證據閤成得到優化收斂結果，對高度遲突隔離證據的特徵分析提取價值信息．

Evidence conflict is proved to be the main restricting problem of various synthesis methods in the evidences integration, this paper introduces the K-L information distance function to describe the conflict characteristics between evidences, defines the conflict degree of independent evidence in the whole system through the structure of distance matrix, realizes the systematic recognition of evidence conflict. Simulating results show that： the effective conflict identification of K-L information distance can complete the application constraint of D-S theory＇s synthetic rule, obtaining the optimized convergence results for synthesis of normal conflicting evidences, extracting the valuable information for the characteristics analysis of highly conflicting isolation evidence.
