The value of rice-fields is being graded down in Korea because it has been estimated only from the size. The purpose of this study is to suggest a management plan in which the location and the size of valuable rice-fields for conservation are based on the results of appraising the worth of ecosystem services of rice-fields in Chungcheongnam-do region. The study is as follows; ①selecting the indicators for evaluating the ecosystem services of rice-fields considering both general functions and special functions in the regional environment conditions, ②classifying the grades of rice-fields in ecosystem service values, ③suggesting the location and the size of valuable rice-fields for conservation, ④calculating the total economic value of the ecosystem services of rice-fields. The results of this study are that the valuable rice-fields’ locations for conservation are the grade I rice-fields and their total area is 100,000ha. Also, the value of the ecosystem services of rice-fields in Chungcheongnam-do region was equivalent to 32.8 trillion won. This amount is over 18 trillion won more than the amount obtained if the total rice-fields in Chungcheongnam-do region were to be transformed to other land-use types. The value of ecosystem services should be considered in the future when appraising the worth of rice-fields, and methods of estimating the ecosystem services of rice-fields need to be developed with a more objective and suitable index.
