ANALYSIS OF COUPLING STATE OF MAN-LAND RELATIONSHIP REGIONAL SYSTEM IN DAIHAI BASIN: A CASE STUDY OF ULANQAB, CHINA

This study investigates trends in the evolution of the coupling state of the man-land relationship and the primary barrier by using a model of the coordination and coupling of the man-land link to the regional system and the Ulanqab in the Daihai Basin as a topic. The next conclusions were reached: (1) Regional development intensity index, resource and environment level index, and trend in collaborative development after 2015 all demonstrated a varying and intertwined growing tendency. (2) After 2004, the coupling degree reached high-quality coupling, and after showing a weak upward trend, the coupling degree reached good coordination in 2012. (3) Effective irrigated area, total area of crops planted, effective irrigated area, and total population at the end of the year were the key barrier variables;(4) It is advised to support integrated urban and rural growth, uphold green development, and improve the hub economy's agglomeration function.
