Abstract: Abstract: The concept and function of land consolidation in China have been continuously enriched and expanded since 1997, which has become more and more significant for the implementation of China's most stringent farmland protection and economical and intensive land use system. This paper reviews China's land consolidation practice and theoretical research of recent 20 years. Land consolidation in China now is experiencing a new adjustment stage after its 3 stages of development. Each stage has different features, of which Stage 1 focuses on the cultivated land quantity supplement, Stage 2 on basic farmland protection and construction, Stage 3 on the comprehensive improvement of the regional land, and now i.e. Stage 4 is taking the ecological concept for the guide. Total conditions about China's land consolidation planning implemented during the "Twelfth Five-Year Plan" is summarized in the paper and its main goal has basically been completed, including the goals of constructing 26.67 million hm2 high standard farmland, supplementing 1.6 million hm2 farmland, and constructing 116 basic farmland protection demonstration areas and 500 high standard farmland demonstration counties. A contrastive analysis on land consolidation objectives and implementation from 2011 to 2015 is made and 5 major problems of China's land consolidation at the present stage are pointed out, which include that the integrated land consolidation practice is still in low level, the pressure on the resources and environment has not been effectively relieved, the implementation effect of the construction land differs greatly in different areas, the land ecological remediation practice level is not high, and the land consolidation funds are instable. At present, China's economic and social development has entered a new normal. An effective way to solve the problems about food security, village reform and urban governance is urgently needed by innovating land consolidation concept, reconstructing land consolidation strategy, objectives and priorities, and breaking the bottleneck constraint of resource on economic growth so as to achieve rational land use comprehensively. Above all, the paper gives 6 suggestions. Firstly, innovate land consolidation concept by taking green development as the land consolidation change direction; secondly, in accordance with the requirements of the development, effectively organize the land consolidation projects by type classification, regional classification and degree classification; thirdly, build more than 10 million mu farmlands with the focuses on eco-farmland construction; fourthly, full strategies should be implemented and supported by land reclamation project; fifthly, promote the land comprehensive improvement and optimize land spatial pattern; sixthly, strengthen the demonstration construction and improve the policy mechanism.
