Abstract
In order to investigate the water conservation effects of Eucalyptus urophylla×E.grandis and Acacia crassicarpa plantations,plots with similar stand conditions were selected,and comparative studies were made on water-holding capacity of canopy,vegetation layer under canopy,litter layer and soil.Results showed that water-holding capacity in different layers of two different plantations were in the order of soil layerlitter layercanopyvegetation layer under canopy.The water-holding capacity of canopy,litter layer,and the water-holding capacity of soil were in the order of A.crasscarpa plantationE.urophylla×E.grandis plantations,but the water-holding capacity of layer under canopy was just the opposite.The total water-storage capacity both above ground and soil in E.urophylla× E.grandis and A.crasscarpa plantation were 1 852.82 and 1 917.72 t/hm2 respectively,and the total value of water conservation for the two plantations were 1 241.39 and 1 284.87 yuan/hm2,respectively.
