Abstract: Abstract In order to evaluate the health status of the Marine ecosystem in the Pearl River Estuary, this paper evaluated the health level of the Marine ecosystem from five aspects: seawater environmental health index, sediment environmental health index, biological residue health index, biological health index and habitat environmental health index. The evaluation results showed that from 2012 to 2018, the water environment, sediment environment, biological habitat and biological residual toxicity indexes of Zhuhai Estuary were mainly healthy, while the biological evaluation indexes were generally sub-healthy, resulting in the evaluation results of the Marine ecosystem health index of the Pearl River Estuary were sub-healthy.
