Based on the analysis of Bijie Citys cultivated land

the rate of urbanization and the changes of regional economic growth trends

the article selected multiple-regression model to study the relationship between area of cultivated land and investment of fixed assets

industrial out put and urbanization.The results showed that cultivated area had been reduced from 4.02×105hm 2in 1988 to 3.65×105 hm2 in 2008 with annual average decline rate 0.48%

meanwhile

percapita arable land also reduced from 0.069hm2in 1988 to 0.047 hm2in 2008 with the annual average decline rate 1.90%.Fixed asset investment

industrial development and urbanizat ion had significant impacts on the reduction of arable land

and their elasticity coefficients were-0.030

-0.002

-0.046

respectively

among which population urbanization exerted the greatest influence.During the past 20 years

the development of urbanization had led to non-agricult uralization of farm land at the expense of the arable land resource.Theref ore

the level of the intensive and economical use of urban land needs to be improved.
