Under the background of three rights separation of rural land,the specific system of long-term stabilization of rural land contracting relation should be built by means of document analysis and induction and deduction.The long-term stabilization is the foundation of the three rights separation.And the three rights separation is a significant theoretical development of the long-term stabilization.The reformation of rural land right structure in China from the two rights separation to the three rights separation provides a strong political guarantee for better implementing long-term stabilization.Sticking to the collective land ownership,the government should work out the specific rules of the longterm stabilization via stabilizing the land contract right.The orderly transfer of land management right should be attached with great importance.The design of specific rules should conform to the concept that there is no adjustment to the contracted lot within the contracting period and at the expiration of contracting term,which should be realized by acknowledging the durative contract and the consecutive contract as indispensible parts of the land contract right.The long-term stabilization should maintain the existing contracting term and clarify the legal situations under which the extinction of land contract occurs.
