Abstract: Because of the contradiction of more people and less land, combining with the threat of land degradation and pollution, land consolidation has become the main way resolving these problems. In the end of 1990's, China issued Land Administration Law, which meant that land development, land arrangement and land reclamation had been promoted to law level and showed the government's attention to land consolidation. At present, ecological civilization has been treated as the national strategy, which needs system framework for land consolidation designed at top level including quantity control, quality management and ecology protection. Unfortunately, a systematic and scientific land consolidation system has not been established on account of theory research work falling behind application work. This paper compared the content, importance and framework level of land consolidation system and land scientific system based on the overseas and domestic research status. Starting from the logic view of land use and cognition, which manifested the procedure of needing land, understanding land, controlling land, fearing land and sustainably using land, the system was divided into the core layer, the supporting layer and the criterion layer. The core layer consisted of technology, theory and discipline. The technology and theory could set up the discipline, while the discipline could accelerate the development of the former two. The supporting layer consisted of management and culture, which could facilitate each other. The criterion layer was land consolidation law, which was treated as a basic standard and guideline for the other systems. It presented the method and principle of how to establish the system framework according to the theory of system engineering and statistics. The results showed that land consolidation system was composed of 6 contents including technology system, theoretical system, disciplinary system, management system, cultural system and legal system. Firstly, land consolidation technology system was the core, which included region classification, investigation, land planning, engineer designation, engineering construction, evaluation, information, technology criterion. Secondly, land consolidation theory system was the basis, which included basic theory, methodology and application. Thirdly, land consolidation discipline system was the impetus, which included major cultivation, personnel training, platform construction, communication and cooperation. Fourthly, land consolidation management system was the main body, which included management object, management subject and management rule. Fifthly, land consolidation cultural system was the soul, which included material culture, spiritual culture and rule culture. Last but not least, land consolidation legal system was criterion, which included law, regulation, rule, normative documentation and institution. The system had the properties of systematicness, innovation and guidance. Systematicness could reflect the attributes' characteristics and the relationship of all the sub-systems. Innovation could fill the current content of land consolidation system using culture connotation and legal criterion. Guidance meant that the technical perfection, theoretical innovation, discipline cultivation and management diversity showed the main development direction of land consolidation in the future. The new view of land consolidation system should be changed, for example, the technology system, theoretical system and discipline system could be treated as core part from only technology system and management system, while management and culture system as the supporting part, and legal system as the criterion. It can be concluded that system framework of land consolidation is a dynamic system, whose content still need to be added and amended in the future.
