Abstract: Building the coding rules for the elements of right to rural land contractual management is a basic work for the information management of rural land. From the right elements of rural land contractual management, party giving out the contract, contractor, plot of contracted land, contract, certificate of the right to rural land contractual management and register for the certificate of the right to rural land contractual management were chosen as the coding targets. Plot of contracted land and contractor were under the united coding of party giving out the contract on the basis of the relationships among the right elements. The codes of contract were the same as the certificate of the right to rural land contractual management and register for the certificate of the right to rural land contractual management, and were connected with contractor. Based on the code of administrative regionalization, the coding structure, coding method and coding rule of above coding targets were proposed in detail. This research had theoretical and practical significance for improving the efficiency of agriculture administrations and promoting the information construction of the right to rural land contractual management.
