A Comparison Study on Water-conservation Capability of Eucalyptus urophylla x E. grandis Plantations at Different Ages
摘要
Abstract
The water-conservation capabilities of litter layer and soil layer in Eucalyptus urophylla ×E. grandis plantations at different ages were compared in Zhenlong Forest Farm, Guangxi province. The results showed that litter accumulation and its maximum water-conservation capacity increased with stand age and reached its peak in 5 yrs old plantation. There were positive relationships between litter accumulation and its maximum water-conservation capacity ( P〈0.05) . Noncapillary porosity and the ratios of noncapillary porosity and capillary porosity gradually decreased with stand age. The water-conservation capacity of 0 - 60 cm soil and the integrated water-conservation capacity tended to decrease with the augmentation of stand age.关键词
