title: [Variation characteristics and calculation model of evapotranspiration in latored soils on hills].
abstract: The dynamic characteristics of evapotranspiration in latored soil on hills of subtropics regions in south China was analyzed. The results showed that evapotranspiration presented annual and seasonal fluctuations. The maximum monthly evapotranspiration was 10.80-15.41 times of the monthly minimum. The evapotranspiration in wet season (March to September) accounted for about 77% of annual total evapotranspiration, and that in dry season (October to February of next year) accounted for about 23%. Although the amount of annual rainfalls could balance annual total evapotranspiration, rainfalls were insufficient for evapotranspiration in the dry season, and soil water could be depleted by evapotranspiration. Based on the modified Penman equation, the calculation model of evapotranspiration in latored soil on hills of subtropics regions in south China was set up. By comparing modeling results with experimental data, it was proved that the calculation model was very reliable.
