| 1. | The result shows that the secular annual mean actual evapotranspiration is 378mm in the yellow river and the error can be controlled in 8 % 模拟结果显示,黄河流域多年平均实际蒸散(发)为378mm ,估算误差控制在8以内。 |
| 2. | The result shows that the secular annual mean basin actual evapotranspiration is 378mm in the yellow river valley and the error can be controlled in 8 % 结果显示,黄河流域多年平均实际蒸散发为378mm ,估算误差控制在8以内。 |
| 3. | 3 . estimation of the actual evapotranspiration with the complementary relationship of evapotranspiration , the actual evapotranspiration were calculated in the yellow river 3黄河流域实际蒸散(发)量估算利用蒸散互补模型,估算黄河流域实际(发)量。 |
| 4. | 4 . distribution of the actual evapotranspiration the maximum of the actual evapotranspiration is on july and the minimum on december . the east ' s value is greater than the west ' s 4实际蒸散(发)量的分布规律实际蒸散(发)最大值出现在7月份,最小值出现在12月份,东部实际蒸散(发)量大于西部。 |
| 5. | It can be used in the larger scale calculation in next research . the main achievements of this project were concluded as follows : 1 . substantiation of complementary relationship for area evapotranspiration based on nearly 30 years data from 432 weather stations and 512 hydrological stations in china , using means of water balance , the secular annual mean actual evapotranspiration was established 为今后进行大范围实际蒸散发研究提供了有益的尝试,本文主要完成以下几个方面工作: 1区域蒸散互补关系的验证利用432个气象站和512个水文站全国共计944个气象、水文站近30年的气象、水文资料,采用水量平衡法,计算流域多年平均实际蒸散发量。 |
| 6. | It was substantiated that the complementary relationship of evapotranspiration on the yellow river valley exists by using ground observed data from weather stations , hydrological and solar radiation observer . actual evapotranspiration was reckoned by model and results were verified by explored the secular annual mean basin actual evapotranspiration which was calculated from water model 本文利用黄河流域气象、水文及日射站的水平面观测资料,证实了流域尺度上存在蒸散互补相关关系,进而采用蒸散互补模型对流域年实际蒸散发量进行估算;用水量平衡法计算的流域多年平均实际蒸散发量对估算结果进行检验。 |
