中文摘要：

安全检查表是一种有效的安全检查工具。对安全检查表进行了改进，对每个安全检查项目根据其重要程度赋予了分值，使安全检查表方法成为一种半定量的指数安全评估方法。以燃气管道为例，介绍了燃气企业安全评估系统中安全检查表设计和安全指数计算方法，在此基础上，开发了安全评估系统，该系统能够对安全检查和安全评估进行高效的管理。

英文摘要：

Safety check list （SCL） is an effective safety check tool. The SCL has been ameliorated, and scores are assigned to all checked items according to their importance, which makes SCL a semi-quantitative safety assessment method. Taking a gas pipeline as an example, the design of SCL and methods for calculating safety index in safety assessment system for gas enterprise are introduced.
