Abstract:: [Objective] The aim of this study is to analyze of agricultural land and water resources matching and carrying capacity level in irrigated areas, so as to promote the high quality development of irrigated areas and ensure national food security. [Methods] This study took the typical irrigation areas of Jiangsu Province as the research object. The matching degree of land and water resources was analyzed by applying Gini coefficient and the matching coefficient method. An evaluation system for carrying capacity of agricultural water and land resources in irrigation areas was established, including water and land resources, economic, ecological and social subsystems. TOPSIS(technique for order preference by similarity to ideal solution), obstacle model and coupling coordination degree model were used to study the health degree, influence factors and coupling coordination degree of the carrying capacity system of agricultural water and land resources in typical irrigation areas. [Results] The Gini coefficient of typical irrigation areas was 0.26, which was better than that of the national averages in the same period. The matching coefficient of water and land resources in all irrigation areas ranged from 2 800 to 11 500 m³/hm², and the matching level of water and land resources was significantly different among different irrigation areas. The carrying capacity system of water and land resources in the irrigation areas was at a medium low level, and the development potential of water and land resource was limited in the current situation. The social subsystem was the key factor affecting the health degree of the carrying capacity system. The carrying capacity system of water and land resources was in a state of basic coordinated development. The coupling coordination degree was positively related to the health degree of the carrying capacity system. The system coupling coordination greatly restricted the development of the carrying capacity of agricultural water and land resources. [Conclusion] Typical irrigation areas of Jiangsu Province have balanced water and soil resources as a whole, and there are significant differences in the matching level of water and soil resources and the health degree of carrying capacity among the irrigated areas. There is unbalanced development among the subsystems of the irrigated areas, and the social subsystem has become a key factor limiting the health degree development of the carrying capacity system.
