摘要:
为了估算黄土高原的水面蒸发量，明确黄土高原干燥度指数的空间分异规律，收集了黄土高原及其周边地区共154站水面蒸发实测资料和216站降水资料，采用克里格插值法，对黄土高原的水面蒸发、干燥度指数进行了分析。结果显示：黄土高原多年平均水面蒸发量变化于1 107~3 308 mm，由东南至西北递增；遥感提取的黄土高原水体面积为1 326.48 km2，占黄土高原总面积的0.21%，黄土高原水体的年总蒸发量为26.28亿m3，占该区多年平均降水量的0.90%；黄土高原半湿润带、半干旱带以及干旱带所占面积比例分别为26.18%，53.73%和20.09%。研究结果对黄土高原水资源利用具有一定的参考价值。
Abstract:
In order to estimate the water surface evaporation and the spatial variation of drought index on the Loess Plateau, the data of 154 evaporation stations and 216 precipitation stations were collected across the Loess Plateau and the adjacent areas. The surface evaporation, drought index of the Loess Plateau were analyzed by using the Kriging interpolation method. The result show that annual average surface evaporation ranges from 1 107 mm to 3 308 mm, increases from southeast to the northwest by turns; water body area is 1 326.48 km2, accounting for 0.21% of total area, the total average annual water surface evaporation of water body was estimated to be 2.628×109 m3 in Loess Plateau combining the evaporation data, accounting for 0.90% of the total annual average rainfall; the percentages of subhumid zone, semi-arid zone and arid zone are 26.18%, 53.73% and 20.09%, respectively. The research result has an important reference for water resources utilization on the Loess Plateau.
