- Abstract:
- Based on the daily observation of meteorological elements including wind speed, maximum temperature as well as minimum temperature from 9 weather station at Akesu basin, the potential evaporation at each grids of the whole basin are calculated through using GIDS (Gradient Inverse Distance Spuared) as Penman-Monteith equation. It is concluded that, the annually averaged potential evaporation of Akesu basin is approximately 84.83 billion cubic meters, the distribution of which is uneven, with its maximum 1 600 mm and minimum around 600 mm. The dominant factors for potential evaporation are the variation of sea level elevation, temperature and humidity. Meanwhile, the general changing tendency of the potential evaporation increased gradually with the decreasing of sea level elevation and the increasing of mean temperature, and the potential evaporation of Akesu basin is just the interval upper limit of the actual evaporation.
