Abstract: It is highly significant for the development of a region to have a well coupled and coordinated water resources system and urbanization system. Based on the construction of the evaluation systems of both urbanization system and water resources system, whose weight was given by the “vertical and horizontal” scatter degree method and expert scoring method, the paper computes and analyzes the coupling and coordination state between the water resource system and the urbanization system in cities and prefectures of Yunnan Province. The results show that: 1) the water resource systems and the urbanization systems in Kunming, Qujing, Yuxi and Honghe are highly coupled and coordinated, while those of the rest of Yunnan Province are in a moderately coupled and coordinated state; 2) In 2010, central Yunnan and Honghe prefecture are high-high concentration areas of coupling coordination degree between the urbanization system and water resource system while Zhaotong, Pu'er and Wenshan are low-high regions, and west Yunnan and northwest Yunnan are low-low regions; 3) In 2017, central Yunnan and Honghe prefecture are still high-high concentration areas of coupling coordination degree between urbanization system and water resource system while Zhaotong, Pu'er and Wenshan are still low-high regions and Dali prefecture and Lincang’s coupling coordination degree changed from the low-low concentration areas in 2010 to high-low concentration areas.
