| Abstract: | The research was made on soil and water conservation function and economic benefit of Ligustrum purpurascens planted in Sloping Land Conversion Program.The results showed that planting of Ligustrum purpurascens can improve the physical characteristics of soil,increase soil porosity and infiltration rate of soils,reduce the soil bulk density,lessen soil erosion and control water and soil loss.The runoff and sediment was decreased 73.19% and 86.51%.And annual dry Ligustrum purpurascens can reach to 375 kg/hm~2.The direct economic benefit can come to 80 000 yuan/hm~2.Therefore,both ecologic and economic benefits of Ligustrum purpurascens land are of great significance. |
