根据近30年甘肃省耕地与经济发展的数据库资料,建立回归模型揭示耕地利用变化与经济发展的定量关系。研究表明：（1）人均GDP、第一产业产值均与耕地面积变化呈显著负相关;（2）耕地利用变化与人口增长、城市化、第一产业增加值、人均GDP、固定资产投资额等与库兹涅茨曲线并非呈典型的倒＂U＂型环境库茨涅茨曲线;（3）经济结构演进与耕地利用变化存在库兹涅茨倒＂U＂型曲线关系。

With related databases of farmland and economic development of Gansu Province in recent 30 years,a regression model is established to reveal the quantitative relationship between farmland change and economic development.The results show that：（1）Either the GDP per capita or primary industry output value is in significantly negative correlation with farmland chane;（2）The relationship between farmland change and population growth,urbanization,GDP per capita and fixed asset investment dose show typical inverted ＂U＂ shaped environmental Kuznets curve;（3）The relationship between economic structure evolution and farmland change shows inverted ＂U＂shaped Kuznets curve.
