Based on the spatial data, this paper studies the spatial heterogeneity of willingness to pay, and discusses the attenuation law and influencing factors of externality value in distance. The results show that the willingness to pay tends to decrease when the distance between the sample point to the Three Gorges Dam increases gradually. The individual factors are added to the regression, the respondents' cognition and travel behavior have a great impact on WTP. Finally, the distance of the boundary of willingness to pay for the policy of returning farmland to forest is 54.90km. Under the influence of individual differences, the willingness to pay produces different distribution results in different distance and social attribute zoning, indicating that the effects of distance and other factors on WTP take place simultaneously and the levels of willingness to pay are heterogeneous. This kind of spatial difference should be fully taken into consideration when calculating the value of externalities and the amount of compensation for the restricted area. By analyzing the externality differences in cognition and payment, this paper can provide a support to improve the differential policies in compensations.
