摘    要:长江流域的四川、湖南和江苏三省,1978-1996年耕地资源面积减少与GDP增长过程具有一定时空变化规律。随着时间的推移和经济的发展,耕地面积减少与GDP增长的相关性逐渐增强;在地区差异上,经济发展程度相对较高的江苏省耕地面积减少与GDP增长间的关联程度要高于经济发展程度较低的湖南省和四川省;随着经济发展程度的提高,耕地资源面积的减少将会由超前型减少转为滞后型减少。最后,作者由上述分析得出了三点结论和启示。

关 键 词:耕地面积  经济增长  相关性  湖南  四川  江苏  时空变化  GDP

Abstract:A certain law of time and space change existed in the reduction of cultivated land area and the growth of GDP from 1978 to 1996 in three provinces along the Yangtze Basin, namely Sichuan, Hunan, and Jiangsu. With the lapse of time and the development of economy, the reduction of cultivated land area has been more and more related to the growth of GDP. In terms of regional difference, relationship between the reduction of cultivated land area and the growth of GDP is closer in Jiangsu Province, whose economic development is relatively higher, than in Huan and Sichuan provinces. With the improvement of economic level, a change in the way of the reduction of cultivated land area will take place. Based on the analyses, the paper draws three conclusions.
Keywords:cultivated land  economic growth  relationship  difference
