Abstract:: The level of intensive use of cultivated land is related to national food security and regional sustainable development. This paper took 18 cities as evaluation units to quantitatively analyze the spatio-temporal variance features of the arable land intensity from 1989 to 2008 in He’nan Province. Methods of optimal weights combination, coordination function, cluster analysis and GIS spatial analysis were employed. The results indicated that the intensive use level of cultivated land from 1989 to 2008 in He’nan Province had been fluctuating up. The level of cultivated land intensive use was prone to be influenced more by investment degree and utilizing efficiency of cultivated land. The intensive use level of cultivated land took an obvious territorial differences and appeared four-grade distribution in provincial domain-wide; it was the highest in north, east and south, secondary in the center and the lowest in the west. The investment degree, utilizing intensity and efficiency of cultivated land appeared evident differences and inconsistency. The authors concluded that the intensive use level of cultivated land from 1989 to 2008 raised step by step in He’nan Province, it was higher in the plain area than that in the hilly area, and unceasingly expanded to the hilly area, the results of evaluation were consistent with the realities.
