| 摘 要： | 在2008年7月～2011年12月通过运用径流场观测方法,对广林巨尾桉人工林土壤侵蚀量和养分流失量进行了定位观测.结果表明,与荒地相比,桉树人工林土壤侵蚀量增加了18.86％ ～146.15％,桉树人工林地土壤侵蚀量造林后呈逐年降低的变化趋势;与荒地相比,桉树人工林养分流失量有所增加(5.75％～ 147.12％),但随着桉树的生长明显降低(97.89％ ～99.98％),桉树人工林地各养分流失量的大小排列顺序为K＞N＞Zn＞P＞Cu＞B.

| Abstract: | Soil erosion and nutrient loss in Eucalyptus plantation were observed by establishment of standard ground surface runoff constructions(20 m×5 m).The results showed that: compared with bare land both of the soil erosion and nutrients in Eucalyptus plantation had increased by 18.86 %~146.15 % while the erosion decreased year by year after plantation with a little nutrient loss.However the nutrient loss is getting less significantly with the growth of the plantation,and the sequence is K﹥N﹥Zn﹥P﹥Cu﹥B. |
