Abstract: Based on the water and land resource data of Xinjiang and other prefectures and cities from 2009 to 2018, an evaluation model of water resources pressure and cultivated land utilization benefits was constructed, and a coupling coordination model was used to conduct empirical research on the coupling relationship between water resources pressure and cultivated land utilization benefits in Xinjiang. The research found that the comprehensive pressure on water resources in Xinjiang had shown a downward trendfrom 2009 to 2018, there was no pressure on population and economic development, and there was greater pressure on ecological and technological development; The social and economic benefits of cultivated land use in Xinjiang had shown an upward trend, but the ecological benefits fluctuated greatly, and the comprehensive benefits of cultivated land use fluctuate greatly affected by the ecological benefits; The degree of coupling and coordination of Xinjiang's water and land resources had shown an upward trend in the past 10 years, but the comprehensive score of water resources pressure was unstable, and the comprehensive benefits of cultivated land use were relatively stable.The pressure on the development of water resources technology in Xinjiang was great, and there were significant differences in the benefits of cultivated land utilization between the north and the south. Therefore, overall planning and coordination of the development and utilization of water and land resources should be strengthened to achieve sustainable development of water and land resources.

Key words: water pressure, farmland utilization benefit, coupling relationship, Xinjiang
