Abstract: Using market value method, opportunity cost method, alternative engineering method and other ecosystem service value evaluation methods, nine ecosystem services of naval orange orchard in south Jiangxi province were evaluated. Nine ecosystem services were production supply, carbon fixation and oxygen release, environmental purification, water conservation, soil conservation, social security, destruction of biodiversity, pesticide pollution, and fertilizer pollution.2020 served as the reference year. The results showed that the total value of ecosystem services per unit area of navel orange orchard in south Jiangxi province in 2020 was 2.02×105 yuan/hm2·a, of which the positive value was 2.08×105 yuan/hm2·a and the negative value was 6.01×103 yuan/hm2·a. The order of positive value was production supply > social security > carbon fixation and oxygen release > environmental purification > water conservation > soil conservation. The order of negative value is destruction of biodiversity > cost of chemical fertilizer pollution treatment > cost of pesticide pollution treatment. The spatial distribution of ecosystem service value of navel orange orchard per unit area was higher in the southeast, and lower in the northwest and northeast. This study was of great significance for comprehensively understanding the value of navel orange orchard in south Jiangxi province, and can provide reference for the evaluation of ecosystem services of other types of orchards.

Key words: ecosystem service, value evaluation, naval orange orchard, south Jiangxi province
