Abstract:: In order to evaluate the spatiotemporal matching situation of agricultural water and land resources correctly in Hetao Irrigation District, the utilization and spatial distribution pattern of the water and land resources were analyzed, and the amount of irrigation water was introduced into the study as the characteristic parameter of water resources quantity, and then a measure model for matching patterns was constructed to evaluate the matching degree of agricultural water and land resources of Hetao Irrigation District and five county regions in this area, the matching degree was graded finally. The results indicated that the agricultural water and land resources showed a situation on the whole that land resources were abundant while water resources were deficient; during the past decade the matching coefficient of agricultural water and land resources was reducing gradually, and the spatial distribution patterns of the two resources exhibited an obvious dislocation phenomenon, the characteristic was that the degree was decreasing from west to east. Against the situation of agricultural water and soil resources in Hetao Irrigation District, strengthening the construction of water conservancy project, speeding up the water management system reform and optimizing agricultural soil and water resources configuration should be conducted to increase the degree of agricultural water and soil resources matching.
