During urbanisation, extensive production and construction activities encroach on ecological spaces, leading to changes in environmental structures soil erosion. The issue of yellow muddy water caused by rainfall cities with high intensity has garnered significant attention. Taking Guangzhou City as the research area, this study is first propose a risk assessment model for intensity, influence sites was fully considered. Rainfall were used indicators assess hazards water. Elevation, slope, normalised difference vegetation index (NDVI), erosion modulus, stream power (SPI), surface permeability, roads represent exposure evaluation indicators. Population number GDP (Gross Domestic Product) vulnerability Based analytic hierarchy process (AHP) method, weights each indicator determined, system established. By overlaying weighted layers different geographic information (GIS) platform, degree distribution map disasters generated. results demonstrated that disaster levels within area exhibited spatial differentiation, areas higher accounting 14.76% total. compared historical event from Guangzhou, effectiveness verified receiver operating characteristic (ROC) curve. validation indicate provides accuracy assessing high-construction-intensity cities, offering effective technical support precise prevention mitigation.
