[Objective] To regulate the market behavior of soil and water conservation technical service in order to provide the technical support for the development of China's soil and water conservation plan and technical service credit evaluation.[Methods] This paper used the related industry credit evaluation system and theoretical analysis as a reference, took soil and water conservation plan compiling technical service as an example, to establish the credit evaluation system. The relevant documents and materials were collected, experts consulting and field investigation was conducted.[Results] In accordance with the principle of index screening processes, seven level Ⅰ index, 21 level Ⅱ index and 47 level Ⅲ index were determined, and formed a technical service credit evaluation index system for complete soil and water conservation scheme compiling. The weight of the level Ⅰ index was determined respectively based on weight factor judgment method and analytic hierarchy process(AHP).[Conclusion] Each index and weight of the established index system in this paper is based on the experts consulting and field investigation, which has a strong realistic foundation and is of great importance in the development of the technical service credit evaluation for soil and water conservation in China.
