Abstract:

It is of great significance to evaluate the key technologies of incremental economic land consolidation in central major grain-producing region, which would promote the transformation of scientific and technological achievements, improve the technological level of land consolidation, the food production capacity and benefit, and would ensure national food security. Based on assessment of the relational concepts, this paper proposed the essence of the central major grain-producing region and incremental economic land consolidation, divided the four key stages of land consolidation concerning the key technologies, and developed a research frame. The frame may include: (1) Using “3S” technology, to divide land consolidation sub-zone in central major grain-producing region; (2) With the technology needs of different sub-zones, evaluating, selecting and integrating the key technologies in the different land consolidation stages; (3) Integrating key technologies system of incremental economic land consolidation in central major grain-producing region, providing the basis for “Project construction key technologies specification of incremental economic land consolidation in central major grain-producing region”, key technologies integration and application demonstration.
