[摘　要]　提出了工程项目生态活力的概念，并描绘出工程项目全生命周期生态活力趋势图和曲线图。从工程项目本身来看，其适应性表现在工程项目自身具备较强的生态活力，在项目种群中处于优势地位，而且在项目群落和项目环境系统中的生态位宽度较大、生态位重叠值较小。

Abstract: Zoology energy of engineering project is advanced in this paper and zoology energy development trend of engineering project in life cycle is protracted. From point of engineering project itself， its adaptability can be shown as its own zoology energy， in the green tree in its engineering population， great niche breath and less superposition in its engineering community.

Key words: engineering project; adaptability; zoology energy; niche
