Summary: This study utilized the random forest method to construct a model for predicting the water quality response to anthropogenic nutrient inputs in Xincun Lagoon. The results showed a non-linear superposition pattern in the intensity of stressors generated by different human activities, with the random forest method being a feasible solution to this phenomenon. The method established in this paper can help identify key pressure sources during the restoration of the lagoon environment to achieve economic and effective outcomes.

Summary: This study proposes a long-term optimal operation method for cascade hydropower stations considering the uncertainty of multiple variables, aiming to maximize the operator's expected revenue and reduce market operation risks through resource allocation and scheduling strategies. It utilizes a seasonal autoregressive integrated moving average model to handle the time-varying and seasonal characteristics of inflow data, and an uncertain chance-constrained programming approach, along with a developed particle swarm optimization algorithm embedded in a Monte Carlo simulation. Simulation analysis based on actual data from cascaded hydropower stations in Yunnan Province, China, shows that the method can effectively describe uncertainty and correlation between variables, providing insights for long-term optimal operation in a multimarket environment.
