In the process of new style urbanization, land quitting is the key to farmers quitting and rural village quitting. The analysis of survey materials of 9 counties of Yunnan Province indicates that policy recognition increases farmers' willingness to withdraw from the land, that non-agricultural capacity has the threshold effect on farmers’ willingness to withdraw from the land, that the functional differentiation effect of contracted land and homestead makes farmers’ withdrawing from the land have difference, that the willingness to withdraw from homestead is weaker than that of the contracted land, that farmer households prefer to choose the withdrawing way with low risk and with stable gain, and that the withdrawing from the contracted land prefers monetary compensation method while the withdrawing from homestead prefers material exchange method. We should strengthen policy publicity to increase farmers' policy recognition, must be vigilant to the trap of non-agricultural border effects and deepen the understanding of the relationship between rural land system reform and urbanization, construct a type of land withdrawing way with step by step, stability and sustainability and take actions that suit the functions of the contracted land and homestead respectively.
