Results show that ( 1) input level, output level, agricultural protection level, and intensive utilization level are the main factors that influent intensive utilization levels of arable land in H enan Province, but the coordination of the four is poor. ( 2) Only measuring the gap betw een the levels of intensive utilization of arable land by input level or output level has certain limitations. ( ) T he intensive utilization levels of arable land in the northern part of Henan Province are higher than other parts. (4) There is a difference in the inconsistency betw een the com- prehensive levels of intensive utilization of arable land and the main factors, that is, input level, output lev- el, agricultural protection level, and intensive utilization level. ( 5) T he intensive utilization levels of arable land show a dow nw ard trend in the w hole
