Abstract: Ecological problems have become a major barrier to the sustainable economic and social development in China. The main way to solve the ecological problems is to carry out ecological governing projects. Reverting Cropland to Forest and Grassland Project is the most typical case among the many major ecological projects implemented in China. However, because the theoretical research chronically lags behind the demands of production practices, the project has to be implemented, adjusted and improved simultaneously. The paper analyzed the main problems and the corresponding countermeasures taken by government at different stages of Reverting Cropland to Forest and Grassland Project and indicated that the ecological problems are the external manifestations of internal conflicts of economic and social systems. The ecological governance projects should not only solve the problems of ecological degradation and damages, but also solve internal economic and social conflicts which might induce ecological problems. Eco-engineering planning and design requires the theoretical support from related disciplines such as ecology, economics, and sociology. At the beginning of major eco-engineering planning and design, it is necessary to take into account the technical reserves, project costs, project achievement stability (the degree that the internal conflicts of economic and social system are solved), promotion, comprehensive benefits, collocation of policies, laws and regulations and other issues. The objectives of considering these factors are to achieve the ideal effect of “both internal and external governance”. All above theoretical methods may avoid the risks and wastes brought by simultaneous government, correction and summary and ensure the realization of the aims of the project.

Key words: ecological engineering, planning and design, reverting farmland to forests and grassland
