However, the patterns and controls of agricultural carbon emissions based on water-land resources coupling effect remain poorly understood in arid inland regions. Thus, we constructed a research framework combining water and land resources with agricultural carbon emissions to assess the linkage of water-land-agricultural carbon emissions in arid inland region. The agricultural carbon emissions measurement model and water-land resources coupling coordination degree model (WLCD) were used for exploring the spatial and temporal patterns of agricultural carbon emissions and water-land elements. The interaction between society factors, economy factors and ecology factors on agricultural carbon emissions was clarified using LMDI (Logarithmic Mean Divisia Index). The applicability of the method was verified in Zhangye in the northwest China. The results are as follows: (1) From 2012 to 2019, the agricultural carbon emissions in Zhangye was rising first and then declining, with 96% of which mainly coming from chemical fertilizers, ploughing; (2) The coupling coordination index of water-land resources in Zhangye increased from 0.3715 in 2012 to 0.5399 in 2019, an increase of 45.33%, indicating a conversion from mild disordered to basic coordination; (3) Regarding the effects among the factors, the economic output of agricultural water resource, cropland area per capita, and population (the water and land resources ratio, and agricultural carbon emissions intensity) exerted positive (negative) impacts agricultural carbon emissions. Accordingly, it is suggested that the development of green and low-carbon development strategies for oasis agriculture requires high level of integrated planning and management of water and land resources, as well as comprehensive consideration of low-carbon agriculture and elements related to water and land.
