Abstract:: Research on construction of ecological environment in the small river basin will not only improve the local ecological environment resistance to natural disasters, but also develop the economy and improve the living standards of local people. Taojia basin was taken as an example, through investigation and using 3S technology,a comprehensive investigation in this basin was carried out. We have obtained the detailed information and data of ecological resources in the Taojia basin, including vegetation resources and land resources,and then we have analyzed and processed the information and data. The results show that some good fields and forest lands were buried by sediment and rocks in the river basin because of the destruction of forest, reclamation on steep slopes and canal leakage in Taojia small river basin. Coverage of forest and vegetation in the upper and middle reaches to only 15.5 percent of the forest coverage now, these changes show a vicious circle of ecological damage-soil erosion and water loss-field decrease-poverty-reclamation on steep slopes-ecological damage. Based on the analysis of the basic ecological background in the river basin, we proposed some suggestions on ecological restoration such as planting soil and water conservation forest, orchard, closing hillside, and so on, in order to provide support for the restoration and the sustainable development of ecological environment in the river basin.
