This paper reviews the study of rural residential areas and discusses the future path. Based on reference data, rural residential area consolidation is concentrated on its consolidation potential, mode, drives, mechanism and benefit evaluation, but less on management system. Much attention is focused at the benefit evaluation in the beginning, but missed in the middle-long term. It concludes that a set of scientific policy management system shall be established to make sure a middle-long term benefits in rural residential area consolidation.

Check of productive capacity of farmlands is an extension of graduation. The farmland productive capacity includes three levels, theoretic productive capacity, feasible productive capacity and actual productive capacity. This paper, by establishing some functions between theoretic unit production of standard crop and natural quality of farmland graduation, and between feasible unit production of standard crop and utilization index, verifies the theoretic unit production, feasible unit production, and based on this, the regional theoretic unit production, regional feasible unit production. The actual productive capacity of farmlands is verified mainly according to the unit production of specified crops in area. Taking a case study on Kaifeng county, Henan province, this paper verifies the productive capacity of farmlands and discusses some related technical questions.
