Abstract: We discussed the comprehensive development and level of coordinated development of economical, social and ecological system of Xijiang River basin in Guangxi, China. Based on the interrelationship among economy, society and ecology, we constructed an evaluation index system that reflects the characteristics of temporal and spatial changes of the “economical-social-ecological” coupled system and its subsystem. We selected data from 2006 to 2016 to study the development index, coordination level, coordination status and time series of the system. The results showed that: ① comprehensive development index of the Xijiang River basin fluctuated, and the economic development index followed a “three-level ladder” pattern. Social development was seriously polarized, and the ecological development index showed large variations in time and space. ② The coordination level of coupled system significantly was improved, mainly within moderate to low coordination level. ③ Coupling coordination degree of economical-social system was lower and more stable than economical-ecological and social-ecological systems, while the coordination level of economical-ecological and social-ecological systems were low.

Key words: construction of ecological civilization, economic-social-ecological system, comprehensive graphic method of fully arranged polygons, coupled coordination model, coupled coordination, Xijiang River basin of Guangxi
