Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of port planning and construction, and in particular to a method and system for assessing the environmental feasibility of port planning and construction. Background Art
[0002] In the field of port planning and construction, environmental feasibility assessment is a key link in ensuring the sustainable development of ports. Traditional port planning environmental assessment methods have many shortcomings: Limitations of multi-factor assessment: Most assessment models use a single factor or a small number of factors, failing to incorporate factors such as environmental carrying capacity, ecological disturbance, pollution diffusion, and socioeconomic impact into a unified dynamic coupling model. This makes it difficult to fully reflect the comprehensive impact of port planning on the multi-dimensional environment. Data collection and processing flaws: Data collection dimensions are limited, and there is a lack of an integrated air-space-ground real-time monitoring network. This makes it impossible to obtain multi-scale ecological data and real-time environmental parameters, resulting in insufficient timeliness and comprehensiveness of model input data. Insufficient model prediction accuracy: Traditional models often use static weights and fixed parameters, without incorporating intelligent algorithms such as deep learning and reinforcement learning. This makes it difficult to accurately simulate complex dynamic processes such as shoreline stress transmission and habitat response, and their ability to depict the interactive effects of multi-source pollutants is limited. Imbalance between socioeconomic and ecological protection: The evaluation system lacks a coupling mechanism between socioeconomic and ecological factors, and lacks quantum computing-based weight allocation and multi-objective optimization strategies, making it difficult to achieve coordinated optimization of environmental and socioeconomic benefits. Insufficient visualization in decision support: Due to the lack of digital twin technology support, it is impossible to dynamically overlay information such as environmental risks and ecological impacts with the port BIM model and GIS data, resulting in low visualization of assessment results and difficulty in assisting decision makers in scientific planning.
