From the conversion relationship between the national use classification and productivity，1 500 kg/ha farmland productivity corresponds to 3 000 national use classification index.Through the total farmland area of all project areas and the increased average national use classification index after consolidation，we calculated the increased average total productivity of each project area（Table 5）.From Table 5，it can be seen that after the implementation of the consolidation project，the largest increase in the average total productivity was Yulin area，because both the increase of average classification index and the total farmland area of this project area were large.The increase in average classification index of Dongtun area was large，but the total farmland area was small，so the increase in productivity was small.For Wanglou area and Weiqiu area，the increase in average classification index was very small，so the increase in productivity was also very small.
