Calculation and simulation of evaporation in Ningxia Plain area;

Various calculating methods of evaporation for the precision survey research area of Jiamusi city were introduced.

Research of Evapotranspiration in Qitai County, Xinjiang Based on MODIS Data;

Based on the energy balance and the distributive regularity of energy expenditure at the earth s surface,this article calculate the changes of air temperature and increments of actual evapotranspiration after the down long-wave radiation getting 1%、2% and 5% increments respectively.

With the first-hand data about the changing rules in cropland evapotranspiration collected by the Ranzhuang Water Resources Experiment Station from the wheat and corn field, an analysis is made on the changing rules cropland evapotranspiration course and depth, and the concerned data range in the condition of experiment is brought forward.
