Abstract: Hanjiang river ecological economy belt is an emerging economic belt across the east and west of the Yangtze River Basin，which has a unique and irreplaceable strategic position in the pattern of regional coordination development. Based on the panel data of 13 prefecture-level cities in Hanjiang river ecological economy belt from 2009 to 2019，this paper introduces the coupling coordination model and constructs a coupling coordination index system of traffic conditions-regional economy-ecological environment in Hanjiang river ecological economy belt to make a comprehensive empirical analysis on coupling coordination development of the three systems in Hanjiang river ecological economy belt. The results show that：（1）the overall coupling coordination of traffic condition-regional economy-ecological environment in Hanjiang river ecological economy belt shows a fluctuating upward trend，and the evaluation level of traffic condition and regional economy lags behind the evaluation level of ecological environment. （2）The comprehensive development level of the three systems between cities is uneven. For the evaluation level of traffic condition and regional economic，Wuhan is far ahead，followed by Luoyang，Xiangyang and Nanyang，and the rest of the cities are relatively backward. While the level of ecological environmental assessment in each city fluctuates greatly with a overall rising-falling-rising trend. (3）For each prefecture-level city，the coupling coordination degree of the three systems experienced stable or fluctuant ascent，generally developing in the direction of benign coordination and eased regional differences.
