| 摘 要： | 运用径流场观测方法,对桉树-牧草、桉树-农作物和桉树-药材3种复合经营模式的地表径流量和土壤侵蚀量进行定位观测,筛选出水土保持效益好的复合经营模式,为桉树人工林的可持续经营提供参考依据.研究结果表明:桉树间作牧草、农作物和药材后,地表径流量分别降低了21.07％～31.02％、33.91％～38.71％和1.51％～67.12％；土壤侵蚀量受人为干扰影响较大,但种植2年后,桉树3种复合经营模式均未产生土壤侵蚀；桉树+木薯复合经营模式的地表径流量和土壤侵蚀量降幅最明显,初步认定桉树+木薯复合经营模式水土保持效益较好,是比较适宜的种植模式. |

| Abstract: | In order to select the compound planting pattern with good soil and water conservation benefits and provide a reference to the sustainable development of Eucalypt plantations, the runoff and soil erosion amount of different planting patterns including Eucalyptus-grass, Eucalyptus-crop and Eucalyptus-herbal medicine were observed in standard runoff plots （20 m×5 m）. The results showed that ： compared with only Eucalyptus plantation, the runoff of other plantations, such as Eucalyptus-grass, Eucalyptus-crop and Eucalyptus-herbal medicine, decreased by 21.07% - 31.02% , 33.91% - 38.71% and 1.51% - 67.12% respectively; soil erosion was obviously affected by human activity in the early-period, but soil erosion was not found in plantation patterns of Eucalyptus-grass, Eucalyptus-crop and Eucalyptus-herbal medicine two years later. Compared with other compound planting patterns, the decrease rate of runoff and soil erosion amount of Eucalyptus-cassava planting pattern was the greatest. Therefore, the Eucalyptus-cassava plantation is considered as an appropriate compound planting pattern with good soil and water conservation benefit. |
| Keywords: | Eucalyptus compound planting pattern runoff soil erosion amount |
