Abstract: Although critical for human sustenance, irrational land use could cause land resources depletion, environmental degradation, food insecurity and social instability. This study uses Landsat images (06/09/1979 and 12/08/2009) with historical precipitation data (1955–2012) to analyze land use change in relation to surface water storage change in Hai River Basin, North China. Based on analysis in ENVI (Environment for Visualizing Images) and ArcMap, land area under water in 1979 is 1.8 % and that in 2009 is 0.6 % of the 23 826 km 2 study area. Although the rate of precipitation decline in 1955–2012 is 4.41 mm/year, it is almost the same for 1979 (582 mm) and 2009 (564 mm). This suggests that drought or flooding has no significant effect on the water storage change. For 1979–2009, land area under forest and grass decreases respectively by 54.2 % and 70.7 %. Then that under settlement, farmland and others increases respectively by 64.8 %, 56.0 % and 63.6 %. The loss of land area under water is 64.6 %, which is more the effect of land use change and the related water use in the region. Irrespectively, more water-efficient land use measures could ensure the sustainability and availability of water resources for future use in the predominantly agrarian semiarid region.
