During the period of rapid urbanization，the shrinking spatial structure of rural population has become more and more simplistic and linear，resulting in a reduction in the social interaction that the structure can carry，and it is difficult to meet the needs of the sustainable development of social，economic and cultural space of villages in the context of rural revitalization.Based on the relevant theories and methods of spatial vitality structure，this paper identifies the vitality structure types of traditional rural space，finds that traditional villages have the semi-network characteristics of “many nodes，overlapping layers and moderate correlation”，constructs a semi-network structure model to stimulate rural vitality，and uses this model to improve the node structure，skillfully set up cross-level overlap reshape the structural vitality of the three industry integration demonstration village by realizing medium correlation.It is expected that the semi-network living structure model will promote the rural revitalization construction in the regions of plains，rivers and lakes.
