基于GEE的黄河口及邻近海域悬浮泥沙质量浓度时空演变及趋势分析
Spatiotemporal evolution and trend analysis of suspended sediment mass concentration in the Yellow River Estuary and adjacent sea areas using Google Earth Engine
摘要
Abstract
Suspended sediment mass concentration(ρSSC)is a key indicator of estuarine water quality,influencing water transparency,turbidity,nearshore ecosystems,and shoreline stability.In this study,ρSSC dynamics in the Yellow River Estuary and adjacent sea areas were analyzed from 1984 to 2024 using satellite remote sensing data processed on the Google Earth Engine platform.We examined the spatiotemporal distribution patterns,long-term trends,and primary drivers of ρSSC changes.Over the 41-year period,ρSSC exhibited a general declining trend,with low-ρSSC waters increasingly dominant.High Suspended sediment mass concentration regions became more localized near the coast,primarily in southern Bohai Bay and the southwestern coast of Laizhou Bay,forming a banded distribution.Theil-Sen Median slope estimation and Mann-Kendall trend analysis revealed significant ρSSC increases in the Qingba waterway and artificial distributary channels,whereas significant decreases were observed in the Qingshui Ditch area.Bohai Bay and Laizhou Bay showed a slight upward trend overall.Human interventions,particularly river course diversions,significantly influenced ρSSC patterns:historical high Suspended sediment mass concentration estuarine zones contracted,whereas new high Suspended sediment mass concentration zones expanded seaward following each diversion.关键词
