As a key point in early-warning of river system health, alert source verification is an important basis for eliminating hidden trouble and maintaining the river system health. Based on the analysis of the alarm source factors affecting the health status of Dongjiang river system, the alarm source index system was constructed, and the alert sources verification model of Dongjiang river system health was established by the partial least squares regression (PLSR) method. This model was used to verify main alarm source factors for affecting the health status of the Dongjiang river system (2015-2019), and the influence trend and degree of different alarm source factor on the health status of Dongjiang river system were analyzed. The results show that annual rainfall is the most direct and significant positive effect factor on the health status of Dongjiang River system. In addition, factors such as ecological water use, social development and river management level in this basin also play a promoting role. However, the flood disaster, sewage discharge, water for production and living, non-eco-friendly water conservancy facilities in this basin, and inter-basin water transfer have obvious negative effects on the health of Dongjiang river system.
