Abstract A clear understanding of the spatial and temporal distribution characteristics water resources is essential for optimal allocation sustainable utilization resources. In this paper, in Henan Province were studied based on GIS, combining Mann-Kendall (M-K) nonparametric test rescaled range (R/S) analysis. addition, SPSS software was used to analyze influence climate land use type The results indicated that (1) hot spots concentrated southwest, while low values northeast, decreased from southwest northeast. (2) past 21 years, spatiotemporal mutations resource sequence occurred between 2010 2014. Z-values M-K trend all less than 0, H-values groundwater (GWRs) mostly greater 0.5, h-values surface (SWRs) total (TWRs) showing an overall declining trend. However, may change future. (3) From correlation analysis, had a impact changes did.
