摘　　要：研究结合遥感技术和地统计空间分析技术,定量分析社会、经济、基础设施要素等不同因子对城市湖泊水体悬浮物浓度变化的影响。通过遥感数据定量反演了武汉市东湖2021年1月20日至1月28日降雨前后的悬浮物浓度,采用地理加权回归分析了事件前后悬浮物浓度变化的空间特征以及不同要素对悬浮物浓度变化的影响。分析结果显示建筑物面积、交叉口数量、道路面积与悬浮物浓度呈正相关;森林、绿地面积与悬浮物浓度在水域边缘区域内均呈负相关。这一研究可为城市环境管理、污染精准防控提供理论支撑。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.
