摘要
蒸发量的分析计算是水资源评价的基础性工作。选用衡水市12处水面蒸发代表站1980~2013年的蒸发资料,计算了单站多年平均水面蒸发量,分析了水面蒸发量的地区分布特点、年内分配及年际变化特征;计算了衡水市各县市的干旱指数,通过干旱指数得出衡水市属半湿润气候区。
The analysis and calculation of evaporation is the basic work of water resources evaluation. Using the evaporation data of 12 water surface evaporation representative stations in Hengshui from 1980 to 2013,the annual average water surface evaporation is calculated. The regional distribution characteristics,annual distribution and interannual change char acteristics of the water surface evaporation are analyzed. The drought index of each county and city in Hengshui is calculated,and the semi humid climate of Hengshui city is obtained through the drought index.
