Research on the changes in water resource conservation capacity caused by the land use of watersheds benefits watershed management and water resource planning. In this study, the Zhuokou River watershed was selected as a research area to collect geological and hydrological spatial data, and to quantify the impact of changes in rainfall and land use on water resource conservation capacity. SWMM used the discharge data from 2015 to 2016 for calibration and validation, and the reliability index the hydrological model was acceptable. Water resource conservation capacity was associated with annual rainfall. In the simulations, the Zhuokou River watershed was divided into nine sub watersheds to analyze the effects of water resource conservation capacity under land use changes. The results indicated that the most serious reduction of water resource conservation capacity was caused by the conversion of forest to building use. The smallest reduction was caused by the conversion of forests to agricultural use. The ratios of reduction in the amount of water resource conservation for building and agricultural use were 0.25 % and 0.03 %, respectively.BASINS/SWMM hydrological analysis model | Land use | Rainfall runoff model | Scenario simulation | Water resource conservation capacity[SDGs]SDG2[SDGs]SDG6[SDGs]SDG13[SDGs]SDG15journal article10.29417/JCSWC.202203_53(1).00052-s2.0-85128646977https://api.elsevier.com/content/abstract/scopus_id/85128646977
