2026-09-15 XDA28100105-Paper-Study of groundwater recharge in the Sanjiang Plain under the influence of land use change doi:10.57760/sciencedb.iga.01364 en In this paper, based on “Strategic Priority Research Program of the Chinese Academy of Sciences” (XDA28100105), in the Sanjiang Plain as the research area, using multiphase remote sensing products and mathematical statistics method, calculate degree of land use dynamic degree and the comprehensive index, build the transfer matrix of land use, The temporal and spatial evolution characteristics of regional land use were expounded. Soil water balance method was used to calculate groundwater recharge in typical years of land use change, and the relationship between land use change, groundwater recharge and its recharge factors was discussed. The SWAT model was constructed, and the verified groundwater recharge results were calculated by combining the historical runoff and comprehensive recharge calculation method, and the numerical simulation of regional water cycle process and groundwater recharge was established. From the perspective of historical land use distribution and specific spatial distribution, the historical change scenario of regional land use scenario and the change scenario of main land use types were set up. The SWAT model was used to calculate the total groundwater recharge and groundwater recharge of paddy field, dryland and wetland, and to elaborate the impact of groundwater recharge change under the main land use change.
