[Objective] The objective of this study is to analyze the impacts of land use change on the hydrological process in the Hongru river basin in order to provide the basis and reference for the rational planning and utilization of local water resources. [Methods] Various scenarios of land use change were designed to simulate the hydrological process in Hongru river watershed based on SWAT(soil and water assessment tool) model. DEM(digital elevation model), land use data, soil data, daily meteorological data were used as the input to establish the SWAT model. Observation data from 2006 to 2008 were used to calibrate and analyze the sensitivity and uncertainty of the established model. Four land use scenarios(S₁: conversion of degraded farmland into forest; S₂: increase farmland; S₃: increase urban land; S₄: increase urban land, forest, and grassland) were set up for hydrological modeling. [Results] The runoff was expected to decrease by 4.23 % in S₁, while it was expected to increase by 3.01% in S₂, 4.91% in S₃ and 1.50 % in S₄. [Conclusion] Returning cultivated land to forest and grassland can reduce the runoff, while reclamation or urbanization will increase the runoff.
