管道泄漏检测是确保燃气管道安全运行的重要技术手段，然而由于城市燃气管网是错综复杂的环状管网，目前尚没有一种方法能较好的对城市管网进行安全监控和泄漏检测。模式识别技术是燃气管网泄漏检测技术发展的方向，针对环状管网应用模式识别技术中存在特征向量维度大的问题，提出了管网分区检测的思想，并阐述了其在管网泄漏检测中的具体步骤。最后通过一实例验证了模式识别法用于城市环状燃气管网泄漏检测的可行性。
管道洩漏檢測是確保燃氣管道安全運行的重要技術手段，然而由于城市燃氣管網是錯綜複雜的環狀管網，目前尚沒有一種方法能較好的對城市管網進行安全鑑控和洩漏檢測。模式識彆技術是燃氣管網洩漏檢測技術髮展的方嚮，針對環狀管網應用模式識彆技術中存在特徵嚮量維度大的問題，提齣瞭管網分區檢測的思想，併闡述瞭其在管網洩漏檢測中的具體步驟。最後通過一實例驗證瞭模式識彆法用于城市環狀燃氣管網洩漏檢測的可行性。

Pipeline is an important technique to ensure gas pipeline safe operation. However, because of city gas pipeline network is a complex system, there is currently no effective leak detection method for its security monitoring and leak detection. Although pattern recognition technology is a development trend of future leak detection technology, it has a huge disadvantage of large dimension feature vectors when used in pipeline network. To solve this problem, network partition detection thought is proposed and its detailed application procedure is described for pipeline network leak detection. Finally, an example verifies this method feasibility for leak detection in gas pipeline network.
