Abstract
The research combines remote sensing technology and geostatistical spatial analysis technology to quantitatively analyze the impact of different factors such as social, economic and infrastructure factors on the concentration of suspended solids in urban lakes. Through remote sensing data, the suspended solids concentration of East Lake in Wuhan before and after the rainfall from January 20 to January 28, 2021 was quantitatively retrieved, and the spatial characteristics of the suspended solids concentration change before and after the event and the impact of different factors on the suspended solids concentration change were analyzed by using geographical weighted regression. The analysis results show that the building area, the number of intersections and the road area are positively correlated with the concentration of suspended solids. The area of forest and green space is negatively correlated with the concentration of suspended solids in the water edge area. This research can provide theoretical support for urban environmental management and precise pollution prevention and control.
