Abstract: The prominent contradiction between supply and demand of urban and rural construction land has been solved to a certain extent by the issuing of the Administrative Measures of Increasing and Decreasing Construction Land between City and Countryside，which gave birth to the rural community construction. Rural community construction has brought a great impact on the rural society，changing the originally social network，which can be seen in the three aspects of rural settlement form，system structure and cultural value structure. The authors point out that the transformation of the rural society should be carried out step by step with respect and adjustment to traditions and local conditions，so as to avoid structural disturbance brought by too radical changes.

Key words: rural community construction, social network, social capital, rural tradition, structural disturbance
