In order to alleviate land use conflict and manage land efficiently, the authors select the typical area of Yanchi County of Ningxia Province as a case, use the LUCIS conflict identification model based on TM data and social economic data, and build a land use tendency evaluation system of construction, agricultural and ecological land. By means of the conflict discrimination matrix, the potential land use conflict types are recognized and potential land use conflict zone in Yanchi County can be divided into 4 types, including dominant area, weak conflict area, moderate conflict area and intense conflict area. Then it is divided into 12 types of conflict zone according to the combination of land use tendency. The result show that 58.90% of the total area faces a risk of potential land use conflict, mostly of moderate conflict, and mainly for the conflict between construction and agricultural land, agricultural and ecological land and conflict among the three types of land use; 6.82% of the total area faces a high risk of potential land use conflict, mainly for the conflict between construction and agricultural land, agricultural and ecological land; 40.88% of the total area belongs to dominant land use area. According to the actual field survey and nearly ten years of policy and system files, driving factors of the conflict are analyzed, and based on the stakeholder analysis, balance strategies for different types of land use conflicts and land use management suggestions in recent and long-term of the county are proposed. This research explores the mutual influence and potential conflict areas of construction, agricultural and ecological land in desertification area, and the contents and methods are as complementary to land use conflict identification, not only having a breakthrough in the research methods of land use related issues, but also of practical significance for the maintenance of ecological security and sustainable social and economic development in desertification area.
