[Objective] Southern red soil hilly area is an important agricultural production base in China, bamboo ditch is a unique slope soil and water conservation measure in this area, and the study of its ecological service function and value is of great significance for the realization of the value of soil and water conservation ecological products. [Methods] Taking Xingguo County, Ganzhou City, Jiangxi Province, as the study area, we comprehensively analyzed the ecological service functions such as soil conservation, water conservation, carbon sequestration and sink enhancement, and mitigation of surface source pollution and their values of bamboo ditch through topographic survey, field investigation and sampling, and testing of physical and chemical properties of the soil, and applying the methods of alternative cost method and market value method. [Results] The soil conservation function and value of different slopes of the bamboo ditch was the highest at the top of the slope, which was 74.86 Yuan/m2?a-1; the water conservation function and value was the highest in the middle of the slope, which was 5.16 Yuan/m2?a-1; the carbon sequestration and sink enhancement function and value was the highest at the bottom of the slope, which was 0.25 Yuan/m2?a-1; the mitigation of surface pollution function and value was the highest at the top of the slope, which was 0.34 Yuan/m2?a-1. The total value of the ecological service function of the bamboo ditch varied in different slopes, including 78.63 Yuan/m2?a-1 on the slope, 57.11 Yuan/m2?a-1 in the middle of the slope, and 60.51 Yuan/m2?a-1 at the bottom of the slope. [Conclusion] Bamboo ditch has important ecological service value in the southern red soil area, and the value varies in different slopes. This study provides a method for accounting the value of the ecological service function of the bamboo ditch, provides a reference for accounting the value of similar soil and water conservation measures, and provides support for the popularization and application of the bamboo ditch.
