Abstract

To clarify the application value and implementation path of BIM (Building Information Modeling) in landscape architecture, this study takes a university campus square as the case, combining questionnaire surveys (101 valid samples), case participation analysis, and comparative research to explore BIM’s full- lifecycle application effects and compare it with traditional 2D CAD technology. Results show that landscape professionals have high recognition of BIM (mean 3.73) but low application level (mean 2.92). Leveraging core features of visualization and coordination, BIM optimizes site ecological analysis in planning, reduces resource waste caused by design conflicts, enhances multi-stakeholder collaboration in low-carbon design, and achieves precise control of carbon emissions and cost-schedule during construction. This study confirms that BIM is an inevitable choice for the green transformation of the landscape architecture industry under the “dual carbon” goals, providing scientific support for full-lifecycle low- carbon project management. Compared with 2D CAD, BIM outperforms in intuitiveness, structural integrity, information comprehensiveness, query efficiency, and engineering quantity calculation. This study confirms that BIM is an inevitable choice for the transformation and upgrading of the landscape architecture industry, providing scientific support for full-lifecycle project management..
