Study on Cultivated Land Resources Use Efficiency in Henan

摘要

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 to analyze the cultivated land resources's 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. Finally, proposed to improve the cultivated land resource utilization efficiency of Henan province and rational utilization of cultivated land resources countermeasures.
