Concept of zoology energy is advanced, zoology energy development trend line and zoology energy development curve of construction project are traced out in this paper. From the point of construction project itself, its adaptability can be shown in its own strong zoology energy, dominant in zoology energy sequence of its engineering population, great niche breath and less superpostion (overlap) in its engineering community. Adaptability of construction project is researched from the angle of ecology which can be taken as basic research of consistent development of construction project, and enrich evaluation system of construction project.
