大型公益项目管理全寿命周期过程集成是指从项目决策、规划设计、实施、运行维护、结束等阶段的项目过程集成。本文以实现项目全寿命周期目标体系为目的，以系统观点、过程观点及价值工程思想为指导，研究了从项目策划、规划设计、实施到运营的全过程集成管理，及其不同阶段不同任务之间的相互关系和作用，建立了大型公益项目全寿命周期过程集成模型，并讨论了大型公益项目全寿命周期过程集成的支撑条件，实现项目全寿命周期的平衡与和谐，提高了项目投资效益和社会公益服务功能，从而提高了大型公益项目的价值。

The life cycle integration management of the large-scale public utility construction projects refers to the process integration of every stage of the project from decisions, planning, design, implementation, operation, maintenance to the end. In this paper, in order to realize the full life-cycle target system, we studied the whole process integration management and the interrelation of different assignments in different phases. The full life-cycle process integration model of large-scale public utility construction projects was proposed. And on this basis we discussed the support conditions of full life-cycle process integration of large-scale public utility construction projects so that the project can achieve balance and harmony in the whole life cycle as well as the investment benefit and social service function can be further improved.
