Water Conservation Effects of Eucalyptus urophylla × E.grandis and Acacia crassicarpa Plantations
摘要
Abstract
In order to investigate the water conservation effects of Eucalyptus urophylla x 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 layer > litter layer > canopy > vegetation 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 plantation > E. Urophylla X 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 x 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.关键词
