Abstract:Farmland is the foundation of agriculture, and agriculture is the foundation of the national economy. Existing farmland can meet the demand for agricultural products, but could not guarantee the building demand. By the end of 2020, construction-using land will reach 1,400 hm2. Unused land in this area has bad quality and is difficult to explore. Farmland is very lack. Countermeasures for protecting farmland is to control population growth, non-agriculture construction occupying farmland,carry out land consolidation and reclamation, improve low-yielding fields and improve farmland productivity.
