The balance of water and land resources system in pastoral ecotone is the guarantee for the development of regional farming and animal husbandry. Taking Yanchi county of Ningxia as an example, this paper evaluates the carrying capacity of water and land resources based on matter element model and studies the driving factors affecting the change of carrying capacity of water and land resources, analyses the factors affecting the carrying capacity of water and land resources and their regional differences, and explores the optimization path of dual guidance of economy and society as well as resources and ecology. The results show that: (1) The carrying capacity of water and land resources of Yanchi county presented a symmetrical X-shaped pattern at a medium level and had great potential for development. Huamachi and Huianpu had higher carrying capacity, while Mahuangshan, Wanglejing and Dashuikeng had the lower. (2) There were obvious regional differences in the coupling and coordination of water and land resources in rural areas of Yanchi county in 2018, and the whole study area was in the antagonistic coupling stage. The coupling and coordination degree of towns was relatively high, while that of rural areas was relatively low. (3) There is a lack of synchronization between water resources and land resources utilization. Water resources lagging areas should take water resources adaptive management and control measures and "ecological conservation + water conservation" to protect mountains, rivers, forests, farmlands and lakes in a coordinated way. Land resources utilization lagging areas should actively explore the main function-oriented zoning, dominant type classification and principal purpose classification optimal distribution strategy of land resources in farming and animal husbandry space in combination with land engineering control measures and industrial restructuring. The strategy of synchronous optimization of resources use, ecological protection and socio-economic development based on the balance of water and land resources in rural areas of Yanchi county provides research reference for the development of agricultural transformation and the implementation of rural revitalization program in the pastoral ecotone.
