摘要：

利用石家庄地区1970-2010年的降水和气温数据，统计分析了该区域降水、蒸发和大气可利用水资源变化特征.研究结果表明：1）石家庄地区降水、实际蒸发和大气可利用水资源均由西部山区向东部平原递减；2）研究区平均年降水量为485mm，其中73%的降水被蒸发损失，17%的降水可被地面利用；3）石家庄地区大气可利用水资源季节分布呈夏季（105mm） > 秋季（15mm） > 春季（8mm） > 冬季（1.5mm）.年均大气可利用水资源呈下降趋势，一定程度上反映了研究区内地表和地下水情况在不断恶化.

Abstract：

Based on monitoring data obtained from 17 national meteorological stations located in Shijiazhuang region during the period of 1970-2010,the change charististics of precipitation,evaporation and available atmospheric water resource were analyzed, respectively.The results indicated that the spatial distribution of precipitation, actual evapotranspiration and available water resource decreased from the west mountains to the east plain.The annual average precipitation was 485mm,and about 73% of the precipitation was consumed by evapotranspiration,and 17% of the precipitation was used by land surface.The available seasonal water resource decreased from summer(105mm) and autumn(15mm) to spring(8mm) and winter (1.5mm).The annual average available water resource showed a decrease trend,illustrating that the situation of surface water and groundwater was getting worse.
