In order to control soil erosion on hilly upland in Southwest He′nan Province,comparative experiments were conducted among Eulaliopsis binata,Amorpha fruticosa and secondary vegetation.Resultsshowed that Eulaliopsis binata and Amorpha fruticosa could significantly improve soil physical properties（p<0.05）:soil bulk density was lowered to 9.15%and 10.56%;total porosity was raised to 10.56%and12.28%;non-capillary porosity was increased to 38.64%and 42.93%;and capillary porosity was increasedto 4.78%and 5.98%,respectively.Planting Eulaliopsis binata and Amorpha fruticosa could remarkablyimprove soil water storage and conservation capacity（p<0.05）:moisture capacity was raised to 15.38%and19.57%;soil maximum capillary moisture capacity,18.14%and 19.57%;and saturated soil water content,4.10%and 4.42%,respectively.Soil permeability was apparently improved（p<0.05）:compared with secondary vegetation,artificially planted Eulaliopsis binataand Amorpha fruticosacould raise soil permeabilityby 2.09and 2.17times respectively.The water absorption rates of stem and leave were:Eulaliopsis binata>Amorpha fruticosa>secondary vegetation.In addition,results showed that the depth of surface runoff, the amount of soil erosion and the amount of soil nutrient loss in the areas with three years′Eulaliopsis binataandAmorpha fruticosa planting were lower compared with those with secondary vegetation only.
