| 摘 要： | 蒸散量是水均衡和能量平衡的重要组成部分, 对全球气候的演变和水资源评价及分析研究十分重要, 而准确估算蒸散量是当今研究热点之一.采用遥感模型, 基于表面能量平衡系统的原理, 选取了MOD09地表反射率和MOD11地表温度、辐射率数据, 并结合实测的气象水文资料对该流域蒸散量进行了估算.海流兔河流域2008年全年蒸散量结果为324.94 mm.这一结果在海流兔河流域, 用水均衡法得到了很好的验证.

Evapotranspiration Estimation of Hailiutu River Basin Based on MODIS Data |
| |
| Abstract: | Evapotranspiration is an important component of both energy balance and hydrological budget. It also plays a major role in both assessment and analysis of water resources and global climate change. Accurate estimation the evapotranspiration is a key issue in hydrological study field. Based on the surface energy balance system, the surface reflection of MOD09 and land surface temperature, emissivity of MOD11 was used to estimate the evapotranspiration of Hailiutu River basin, combined with the observed meteorological and hydrological data. The results indicate that the annual evapotranspiration of Hailiutu River basin in 2008 is 324.94 mm, which is validated by water budget. |
