| 摘 要： | 河南省作为粮食大省,近些年粮食种植面积和产量基本保持了稳中上升的态势.1998年到2004年,河南省耕地压力指数大于1.2003年耕地压力最大.2005年以后,河南省耕地压力指数小于1,并逐步下降.预计十二五时期河南省耕地压力指数将继续稳步下降.要确保实现这一目标,需具备的条件包括控制人口规模、继续增加耕地面积、控制工...

| Abstract: | As a large province in grain,Henan has seen a steady upward trend in grain planting area and output in recent years.From 1998 to 2004,the pressure index of cultivated land in Henan was more than 1.There was the greatest pressure of cultivated land in 2003.After 2005,the index became less than 1,and gradually declined.It was expected that pressure index would continue to decrease slowly during the Eleventh Five-Year Period.For this goal,there are some conditions to be met,which are to control the population ... |
