Artificial Intelligence-Empowered Ecological Wetland System: A New Model for Nitrogen and Phosphorus Pollution Control in Lakes—A Case Study of Lake Dianchi
Lake Dianchi, the largest freshwater lake on the Yunnan-Guizhou Plateau, has suffered from severe eutrophication due to excessive nitrogen (N) and phosphorus (P) inputs. Conventional constructed wetlands show large seasonal efficiency fluctuations and lagged management responses. Here we propose a four-layer AI-wetland framework (perception, analysis, decision, execution) and validate it at the 383-ha Hai-Hong wetland. An XGBoost-SHAP model predicted 7-day N/P removal rates with ±10% error; a Delft3D-based digital twin was coupled to NSGA-II for multi-objective optimisation. Compared with traditional static operation, AI-driven dynamic control increased annual total N and total P removal by 15% and 15%, respectively, and reduced cash OPEX by 22% (Table 2). During a 50-year storm event, the system lowered peak outflow TP by 30% through preemptive water-level drawdown. Although up-front CAPEX (≈ CNY 18-22 million) was financed by green bonds, annual major-repair reserves (2% of CAPEX) and ICT electricity must be budgeted. The study provides a replicable, cost-effective pathway toward SDG 6.

Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
The study employs advanced computing methodologies, particularly machine learning algorithms like XGBoost (eXtreme Gradient Boosting), for predictive modeling. This involves data pre-processing, model training with gradient-boosting and random-forest regressors, and attribution using SHAP values to identify key drivers. The framework also integrates digital twin technology, specifically a Delft3D-based hydrodynamic-water-quality-ecological model, coupled with NSGA-II for multi-objective optimization. This combination enables dynamic control and real-time decision-making, moving beyond static, empirical approaches. The execution layer utilizes cloud-compatible actuators and LoRaWAN+4G dual-link modules for rapid command latency and closed-loop verification.
This research directly addresses critical issues in environmental sciences, focusing on nitrogen and phosphorus pollution control in freshwater lakes, specifically Lake Dianchi. It proposes an AI-empowered ecological wetland system as a novel solution to severe eutrophication. The system aims to enhance N/P removal efficiency and operational stability, which are common challenges for traditional constructed wetlands. By integrating IoT for real-time monitoring of water quality and macrophyte health, and using AI for predictive modeling and optimal decision-making, the system offers a more precise and resilient approach to sustainable water management and achieving UN SDG 6.
