Abstract: As agricultural land circulation was becoming more frequent, demands of land circulation information have become increasingly high. And the supervision and approval of the government departments also need higher requirements. To accelerate the reasonable transfer of agricultural land, we designed the platform with modern information technique. Efficient and smooth circulation is a crucial factor in improving the efficiency of agricultural land use and household incomes. Through analyzed the status quo of agricultural land transference and guided by practicability of platform construction, the author established agricultural land circulation systems of B/S structure based on J2EE technology. In this process, the network technology, computer programming and database technology were applied. The functional structure was programmed firstly, and then the system flow and database structure were designed appropriately. This system achieved the following functions: the registration of agricultural land information and its automatic updating, which can guarantee the symmetry of circulation information and smooth the information channels. The system established an administrator-track management mechanism of circulation business. It achieved a complete succession of business process of circulation, which including the administrators approval at all levels and contracts filing business, and all of these would improve the management efficiency significantly.
