To this phase, issues of ecological health start to appear. New attempts were made to introduce the concept of ecosystem health to the project both theoretically and practically. At present, there is no an operational definition on the ecological system health due to the lack of the research in this field, and thus no systematic research system has been formed. Especially in China the studies just begin and need to investigate and get more information. Based on the present situations of grain for green project, this paper introduced the concept of ecological health of grain for green project. The history of the development of the concept was reviewed. The paper tried to establish diagnostic indications for the assessment of the ecological health of the project. Some suggestions were given on the promotion of vegetation restoration.
