Evaporation of Different Forest Vegetation Types in Mountainous Areas of Eastern Liaoning

ZHANG De-cheng et al(College of Forestry,Shenyang Agricultural University,Shenyang,Liaoning 110161)  
Comparative studies evaporation of such 7 representative forest vegetation types as young growth larch,half-mature larch,young growth Korean pine,half-mature Korean pine.oak,weed tree,corpland in mountainous areas of eastern Liaoning by detecting the fix plots.The results indicated that evaporation in young growth larch is more lower than the others,and the cropland's is the most high.The most important factor to effect the evaporation is litter on the forest ground and there is negative correlation between evaporation and covering,Evaporation of the layer from soil surface to 20 cm is dominant as the lower soil lost less water than the upper.Water in the Korean pine's soil exchange up and down upon 20 cm and the crop's can exchange each other upon 25 cm.According to the model of BLANEY-CRIDDLE,the amount of evaporation in each vegetation types in mountainous areas of eastern Liaoning is counted.It refer to amount of the evaporation is hight in summer and little in winter as inflation from mouth to mouth.
