摘要：针对施工现场临建设施的特点，以十六组已建项目的工程造价数据为基准从生态经济平衡、建造经济合理、运营机制协调三方面构建评价指标体系。利用模糊物元理论，建立施工现场临建设施绿色度评价模型，通过计算样本模糊物元与理想模糊物元的相对关联度值，判断施工现场临建设施绿色度等级；最后应用实例，计算实例临建设施绿色度并确定其等级。

Abstract：According to the characteristics of construction site construction facilities，establishes an evaluation index system from three aspects of ecological economic balance，construction economic reasonability and operation mechanism coordination based on the project cost data of 16 groups of built projects. Establishes the evaluation model of greenness of construction site emergent facilities by using the fuzzy matter-element theory. Judges the greenness level of construction site emergent facilities by calculating the relative correlation degree value between sample fuzzy matte and ideal fuzzy matte. Finally，calculates the green degree of the facilities and determines its grade.
Keywords：temporary construction facilities；rough set；fuzzy matter-element model；green degree；sample analysis
