This invention relates to the field of environmental monitoring and ecological assessment technology, aiming to address the limitations of existing technologies in accurately diagnosing the degradation mechanisms of intermittent river ecosystems, tracing stress sources, and simulating scenarios. This invention adapts to the monitoring needs of both wet and dry periods by collecting eDNA from water and sediment dual samples, integrates multi-source data to extract specific biological index characteristics of intermittent rivers, and uses a hierarchical Bayesian causal network model incorporating specific ecological knowledge to distinguish between natural hydrological fluctuations and anthropogenic disturbances. Finally, it outputs the dominant degradation factors of intermittent rivers and ecological regulation recommendations. This invention overcomes the bottlenecks of traditional monitoring in intermittent river scenarios, such as the lack of monitoring during dry periods and ambiguous attributions, improving the accuracy and specificity of diagnosis, and providing scientific support for the ecological protection, ecological flow determination, and restoration plan formulation of intermittent rivers.

The present application relates to the field of ecological protection data processing, in particular to an ecological management evaluation method based on ecological pattern and an ecological integrated monitoring system. The method proposed by the present application determines an ecological pattern evaluation matrix based on six dimensions according to an ecological pattern data set, and obtains a dynamic weight distribution model based on an ecological management target. The weight matrix obtained in the dynamic weight distribution model is multiplied by the ecological pattern evaluation matrix to obtain the evaluation score based on different ecological management targets, so that the completion of the ecological management target can be judged. The method of the present application focuses on the ecological pattern level, comprehensively integrates multi-dimensional ecological information, and systematically reflects the overall characteristics and operating state of the ecological system. A unified weight adjustment model is used to flexibly adapt to different management targets such as ecological protection, ecological planning and ecological restoration, and there is no need to build a complex evaluation system for each target.
