Ecological restoration is the development of eco-construction of soil and water conservation. Based on analysis of characteristic of soil erosion, progress, tendency of eco-restoration research, and existing problems, this paper presented the further research area on eco-restoration of soil and water conservation including potential and driving factors of eco-restoration, configurations of different scales eco-restoration, technical measures and standards of eco-restoration, healthy assessment of ecosystem of watershed scale, impact of soil and water conservation on eco-hydrological process, vegetation ession, bio-diversity and agricultural economy.
