To improve the connectivity of high standard prime farmland regions, on the basis of arable land comprehensive quality evaluation and the arable land connected network, a local farmland connectivity calculation formula was proposed to evaluate arable lands connectivity, and four-quadrant method was adopted to space couple farmland quality and connectivity. Firstly, arable land comprehensive quality evaluation system was built from natural quality, site environment and ecological quality by using the analytic hierarchy process. Secondly, on the basis of contiguous thresholds and contiguous rules, the arable land connected network and arable lands connectivity evaluation system was built. Finally, four-quadrant method was adopted to zone high standard prime farmland, which included prioritized construction area, important construction area and conditional construction area, and it can provide reference for the construction of high standard prime farmland. The results showed that the area for prioritized construction was 24803.45hm2, where the arable lands had better quality and higher connectivity; the area for important construction was 19688.77hm2 and 19538.64hm2 for conditional construction area, each region included three types of construction and each construction had different sequences. A global farmland connectivity calculation formula was also proposed. Compared with the method of accumulation area, the connectivity of prioritized construction area was improved by 15.55%, while the connectivity of conditional construction area was decreased by 37.82%, indicating that the method significantly improved the connectivity of high standard prime farmland construction area.
