Based on the background of construct the national grain strategy project of Henan province core and construct Zhongyuan Economic Zone, considering the Henan province's cultivated land resources use efficiency and food security, using multiple linear regression model and the principal component analysis to analyze the cultivated land resources’ use efficiency between 1999-2008 of Henan province, drew this decade, cultivated area remain basically stable, Cultivated land utilization overall efficiency is high, and established the food production, even in successive years grain output reached a high yield, population density, urbanization rate, per capita GDP, multiple crop index, per hectare fertilizer rate is the greatly influenced factors of influence cultivated land resource utilization efficiency. The main factor that influences grain output has converted from per hectare fertilizer to the quantity and quality of labors in per hectare; the increase of multiple crop index and level of agricultural mechanization are the important factors that influence the grain output. Finally, proposed to improve the cultivated land resource utilization efficiency of Henan province and rational utilization of cultivated land resources countermeasures. Based on the analysis above, this paper indicate that: 1) Promote urbanization, strengthen land management to protect cultivated land resources; 2) Control copulation and improve land use efficiency; 3) Improve water resources in a rational allocation between sectors; 4) Increase input in agriculture, science and technology, to improve land productivity.
