Abstract:: Relatively limited land resources has become the bottleneck of economic development,the study of relationship between farmland resources changes and economic development is very important.The paper selects the GDP and farmland area as indexes to discuss the logarithmic relationship between farmland resource change and economic development in Hebei province during 1978-2004 based on the analysis of farmland resources change in the past 30 years,meanwhile it estimates the lost areas for farmland when increasing the equivalent GDP in different economic development levels using the index correlation between farmland area and GDP growth.The results show that:(1) The farmland areas show the trend of logarithmic decrease with the increase of GDP and the fitting coefficient between them is high,which proves that using the model of logarithmic decrease to predict the change of farmland area with GDP growth has a good feasibility.(2) The lost areas for farmland are different when increasing the equivalent GDP in different economic development levels.When GDP in the stage of 2000~4000 billion yuan,4000~6000 billion yuan,6000~8000 billion yuan,with the GDP growing per 2000 billion the lost areas for farmland are 3.85×10⁴ hm²,2.25×10⁴ hm²,1.60×10⁴ hm² respectively.
