Abstract:

It is important to evaluate the external benefits by preserving agricultural land,because this can provide a scientific basis for ruralurban land conversion decisionmaking,and also decrease the risk of high quality agricultural land loss.In this paper,the authors use the contingent valuation method (CVM) to evaluate the external benefits of agricultural land preservation in Jianghan Plain based on 789 valid questionnaires.Several conclusions can be drawn from the study.Firstly,the residents (both farmers and urban citizens) recognize the external benefits of preserving agricultural land,based on an increased awareness of agricultural land protection.According to the survey,8550% of the respondents have a positive willingness to pay (WTP) to protect agricultural lands.Secondly,according to the residents’ WTP to protect local agricultural lands,the external benefits of preserving agricultural land may be quantified as at a total of 2805×108 RMB Yuan,being almost 48 658 Yuan per hectare.Nowadays,the external benefits of agricultural land preservation in Jianghan plain reach a total of 2 45623 hundred millions Yuan,which is about 9fold of the whole gross domestic product of Xiantao City in Hubei Province.

Key words: agricultural land preservation, external benefit, willingness to pay, contingent valuation method (CVM), Jianghan Plain
