摘要：
A modeling approach was utilized to investigate the impact of increased atmospheric CO2 and temperature on water balance, crop production, plant growth, and soil erosion. For the given scenario and the site tested. the increase of temperature resulted in a significant increase of ET, reduction of soybean canopy cover and yield, a slight increase in soil loss, and a reduction in soil moisture. However. the increase of atmospheric CO2 resulted in significant increase of crop yield and canopy cover, a slight reduction of ET, and a slight reduction of daily root zone soil moisture, storm runoff, and water induced soil erosion of the corn field.
