[Objective] The interaction between urbanization system and water resource system was studied in order to provide a scientific basis for the correct evaluation of the coupling and coordination relationship between urbanization and water resources, and to provide decision reference for promote the coordinated development of regional population, resources, economy and ecological environment.[Methods] Apply coupling and coordination research achievement, the urbanization evaluation index system was established from three aspects of population urbanization, land urbanization and social urbanization build. Water resource evaluation index system was established from water resources levels, water resource stress and water resource management, and then the coupling and coordination evaluation index system about urbanization and water resources was established. Based on the relevant data from 2008 to 2017, the coupling degree development index and coordinated development degree between urbanization and water resources in Yunnan Province was quantitatively calculated. According to the classification of coordinated development types, the coordinated development types and comparison types in Yunnan Province during the study period were divided, and the coordination status was evaluated. At the same time, with the support of GIS technology, taking 2008 and 2017 as the time points, the spatial pattern characteristics and spatial pattern of variation characteristics between urbanization and water resources in different cities (states) in Yunnan Province were studied.[Results] ① From the characteristics of time series, the coordinated development of urbanization and water resources experienced two phases, namely, run-in phase and coordination phase.② The urbanization lag had shifted to water resources lag since 2013 in Yunnan Province. ③ From the feature of spatial pattern, the spatial pattern with Kunming City as the center gradually changed from the central "coordination" to the edge "disorder".[Conclusion] There is a high degree of interdependence between urbanization and water resources in Yunnan Province. The coordinated development and overall development trend is good, but the spatial difference of the coordinated development types is significant. The process of urbanization has promoted the efficiency of water resources, at the same time, the improvement of support of water resources for economic and social development effectively promoted the process of urbanization.
