[Objective] The aims of this study are to comprehensively evaluate the soil and water conservation of construction projects, diagnose their obstacle factors, and to improve the comprehensive performance of soil and water conservation. [Methods] A comprehensive evaluation index system for soil and water conservation was established using four subsystems, including the effectiveness of soil and water loss prevention and control, the control of soil and water loss impact factors, the control of soil and water conservation economic investment, and the effectiveness of soil and water conservation ecological construction, as well as 15 indicator factors under them. Based on analytic hierarchy process(AHP), expert scoring method and entropy weight method combined with game theory were used to construct a comprehensive performance evaluation technology system and obstacle factor diagnosis method for soil and water conservation of construction projects with combined weight TOPSIS model. Empirical research was carried out to evaluate and diagnose 3 construction projects in Shaanxi Province comprehensive benefits and obstacle factors of soil and water conservation of the project. [Results] The comprehensive performance closeness of soil and water conservation projects for P1, P2 and P3 are 0.764 4, 0.692 8 and 0.274 5, respectively. The soil and water conservation performance of P1 is excellent, while that of P3 is poor. The main indicator layer obstacle factors of P1 are the investment ratio of forest and grass measures and the investment ratio of temporary measures. P2 represents the disturbance land remediation rate, unit area waste, temporary measure investment ratio, and forest and grass vegetation restoration rate. P3 represents the disturbance land remediation rate, soil erosion control degree, and forest and grass vegetation restoration rate. P1 needs to optimize the investment structure of water and soil conservation measures, increase investment in forest and grass measures and temporary measures appropriately. P2 needs to increase investment in temporary measures appropriately, improve the effectiveness and comprehensiveness of water and soil conservation measures. P3 needs to increase capital investment and increase temporary measures and forest and grass measures. [Conclusion] By using the combined weighted TOPSIS model, the soil and water conservation obstacle factors of construction projects can be accurately diagnosed and the soil and water conservation benefits of construction projects can be improved. The ideas and methods of this study can provide technical ideas for promoting the comprehensive performance improvement of soil and water conservation in construction projects and systematically optimizing and adjusting soil and water conservation plans.
