Outline
Building on the concept of ecosystem quality, this study developed a theoretical indicator system constructed around four dimensions: ecological pattern, biodiversity, ecological function, and ecological stress. Taking the Bohai Bay, the Changjiang River Estuary, and the Zhujiang River Estuary as study areas, multi-source data from 2003 to 2023 covering seawater and sediment quality, phytoplankton, zooplankton, macrobenthos, and fish eggs and larvae, were integrated and analyzed. Cross-dimensional correlation analysis and within-dimension multicollinearity diagnostics were applied to streamline the indicator set. Results indicated that sediment total organic carbon, seawater ammonia nitrogen, and fish egg/larval density showed no significant correlation (P<0.05) with most other indicators in cross-dimensional tests and were therefore removed. Within each dimension, indicators were significantly correlated, enabling further simplification through the retention of representative measures: salinity for ecological pattern, density metrics for biodiversity, and inorganic nitrogen, reactive phosphate, and petroleum (which carried independent information) for environmental stress. Consequently, the original set of 36tertiary indicators was refined to 9 core indicators: ecological pattern (seabed light transmittance Fr, salinity), ecological function (chlorophyll-a), biodiversity (phytoplankton, zooplankton, and macrobenthos density), and ecological stress (inorganic nitrogen, reactive phosphate, petroleum). This simplified indicator system maintains scientific rigor and representativeness while enhancing data acquisition efficiency and practical feasibility.
