    Water resource is an important strategic resource for sustainable development and a basic resource for ecological environment construction, especially in southwest karst area of China. Based on the concept model of DPESFR (Drive (D), Pressure (P), Engineering water shortage (E), Status (S), Ecological foundation (F), Response (R)), this study built a comprehensive assessment indicator system based on characteristics of karst water resources. Entropy-weight right method, CRITIC method and AHP method were utilized to determine three types of basic weights, and coordinated weights of all indicators were obtained by combining the thought method of game theory. Matter-element analysis model was utilized to calculate water resources safety situation of Guiyang from 2013 to 2022, and the limiting factor was explored by the limiting degree model. Finally, Autoregressive Integrated Moving
