中文摘要：【目的】研究港珠澳大桥对珠江口海域悬浮泥沙分布的影响。【方法】利用2019年冬季珠江口海域的出海调查数据和高分1号卫星遥感数据,建立珠江口海域悬浮泥沙的遥感反演模型,分析大桥对悬浮泥沙空间分布的影响。【结果】高分1号卫星的4个波段中,第4波段与悬浮泥沙浓度的确定系数最高,线性模型的确定系数达到0.58,而4波段组合模型的效果最好,确定系数可以达到0.74;大桥对悬浮泥沙的输运有比较明显阻滞作用,大桥两侧悬浮泥沙浓度的差值最高达7mg/L。【结论】港珠澳大桥对珠江口海域悬浮泥沙的空间分布有比较明显的影响。

外文摘要：【Objective】To study the influence of Hong Kong-Zhuhai-Macao Bridge on the distribution of suspended sediment in the Pearl River Estuary.【Method】Based on the investigation data of the Pearl River Estuary in winter 2019 and the remote sensing data of GF-1 satellite,the remote sensing inversion model of the suspended sediment in the Pearl River estuary is established,and the influence of the bridge on the spatial distribution of the suspended sediment is analyzed.【Result】Among the four bands of GF-1 satellite,the determination coefficient of band 4 and suspended sediment concentration is the highest,the determination coefficient of the linear model is 0.58,and the combination model of 4 bands is the best,the determination coefficient can be 0.74;the bridge has an obvious blocking effect on the transport of suspended sediment,and the highest difference of suspended sediment concentration on both sides of the bridge is 7 mg/L.【Conclusion】The Hong Kong-Zhuhai-Macao Bridge has some influence on the spatial distribution of suspended sediment in the Pearl River Estuary.
