Abstract:: Over the past century, global climate has become warming significantly, which changed the regional hydrologic cycle potentially. In recent 50 years, temperatures keep increasing; water deficit is serious in Haihe River Basin, which has affected the development of society and economy. In order to explore the spatiotemporal characteristics of climate change, the Haihe river basin is divided into three areas as Plateau, Hills, Plain according to the landforms’ spatial heterogeneity. The spatial and temporal patterns of 8 meteorological elements at 34 meteorological stations from 1958 to 2011 were analyzed by using linear trend for inter-annual trend; using the Mann-Kendall test for significance test; using Spearman method for correlation between meteorological elements and ET₀ calculated by Penman-Monteith formula. This work is to reveal the regularity of temporal and spatial variation of meteorological elements and the possible driving forces of regional water cycle. The results show that there existed obvious climate change in Haihe River Basin, the temporal and spatial variation of meteorological elements presented obvious zonal, seasonal and interannual characteristics. The temperature went through dropping first and then rising up. Plateau rising speed was faster than Hills and Plain. Precipitation was generally falling. And precipitation of Plain region fell more than Plateau and Hills. Average wind speed, sunshine hours, relative humidity were obvious downward. The potential evaporation was negatively related to the relative humidity, positively related to daily temperature range in Haihe River Basin.
