Assessing the effects of vegetation on soil and water conversation is the key basis for research and management of ecological restoration in water-eroded areas. In this study, the runoff depth, soil loss and corresponding precipitation of five plots planted with Pueraria lobata, Lespedeza bicolor Turcz, Manglietia yuyuanensis Law, Paspalum natatu Fliigge, Paspalum wettsteinii Hackel, respectively, and one control plot were observed monthly from 2003 to 2010 in Hetian Town of Changting County, Fujian Province, a typical water-eroded area in southern China. Then the effects of different vegetation on water/soil conversation (RE/SE) were determined using the ratios of runoff depth and soil loss in vegetated plots to the counterparts in the control plot. Meanwhile, the effect of rainfall on the soil and water loss was also analyzed. The results showed that the effects of Pueraria lobata and Manglietia yuyuanensis Law on soil and water conservation were better than those of Lespedeza bicolor Turcz and Paspalum natatu, while the effect of Paspalum wettsteinii Hackel was the worst. The differences of effects of water conservation were more significantly than those of soil conversation between five kinds of vegetation. The runoff depth was mainly affected by rainfall, and the determination coefficients (R2) of linear regression models between rainfall and runoff depth of all planted plots were all greater than 0.9, whereas the determination coefficients of the linear regression models between rainfall and soil loss varied from 0.3 to 0.8 for different vegetation plots. These results provide a reference for vegetation reconstruction in the current and similar areas.
