Article: Landscape infrastructure optimisation design based on a BIM-GIS coupling model Journal: International Journal of Environment and Sustainable Development (IJESD) 2026 Vol.25 No.6 pp.128 - 148 Abstract: Due to insufficient integration of spatial constraints, existing methods often fail to achieve global optimisation in balancing multiple objectives such as ecological benefits, landscape accessibility, and construction costs, thereby hindering the scientific nature of design and its implementation efficiency. This paper aims to address the challenge of difficult collaborative optimisation of spatial patterns and component parameters due to the separate application of BIM and GIS in landscape infrastructure design, proposing a BIM-GIS deep coupling optimisation method based on multi-level spatial constraints. This method constructs a unified coding system through spatial semantic matching and 3D geometric alignment, and uses a joint similarity function to achieve high-precision mapping between BIM components and GIS elements. The experiment shows that the average geometric alignment error of this method is 0.08 m, the average convergence iteration is 42 times, and the maximum performance degradation rate under disturbance robustness is only 8%.

Abstract: Due to insufficient integration of spatial constraints, existing methods often fail to achieve global optimisation in balancing multiple objectives such as ecological benefits, landscape accessibility, and construction costs, thereby hindering the scientific nature of design and its implementation efficiency. This paper aims to address the challenge of difficult collaborative optimisation of spatial patterns and component parameters due to the separate application of BIM and GIS in landscape infrastructure design, proposing a BIM-GIS deep coupling optimisation method based on multi-level spatial constraints. This method constructs a unified coding system through spatial semantic matching and 3D geometric alignment, and uses a joint similarity function to achieve high-precision mapping between BIM components and GIS elements. The experiment shows that the average geometric alignment error of this method is 0.08 m, the average convergence iteration is 42 times, and the maximum performance degradation rate under disturbance robustness is only 8%.
