At present,the ecological environment in the countryside of China is deteriorating with industrial pollution spreading to the countryside,agricultural pollution on the increase and environment in the residential areas deteriorating. The traditional approach to the ecological problem,which heavily relies on the government or the market,fails to fundamentally address the problem. Instead,as the social capital in the countryside,the relationship network,norms and trust can effectively resolve rural ecological environmental crisis by highlighting the method of"social governance"in ecological environment in the countryside. It is thus suggested that in the governance of rural ecological environment,which is based on the social capital,the management space between the government and the community should be appropriately divided,so that the institutional capital can promote and regulate the social capital,enhance the construction of rural cooperative organizations and increase the input of rural human capital,and promote the coupling between administrative boundary and ecological boundary.
