The option value is an important part of the nonuse value in the area of resource science.In order to evaluate the total value of farmland and study the option value of ruralurban land conversion further，this paper reviews international and domestic academic literature on option value，and analyses the development and the trend of the recent research on option value by methods of documentation and induction.The study shows that the achievements of the option value are different，and the study emphasis is different at home and abroad.Domestic scholars have studied option value，existence value and bequest value as a whole.The content is single and the method is qualitative mainly.The international scholars focus on the option value individually.The content of their researches includes the concept，connotation and estimation method.They also apply the option value into a series of realistic problems such as whether to protect the resources or whether to invest and so on.It shows that the international researches on option value appear more mature.Our scholars should extract the foreign experience and study the foreign achievement，in order to apply it into our research on the evaluation of the land and establish the theoretical base for the decision of ruralurban land conversion.
