The farmland is the most basic natural resources.Its amount and quality relates to the food safety and the life of mankind directly,which is one of the important aspects of keeping a sustainable land development.This paper used the data of social economy statistics and weather during 1979-2004 in Yutian County,carried on principal components analysis by selecting 15 artificial and natural factors and diverse return model of dynamic farmland.The results indicate that the main factor which influences farmland is artificial factor.The changes of total population is the biggest contribution rate and the influence of natural factor is smaller.Although the change of weather doesn’t influence on the farmland area greatly,farmland area have certain influence on the weather.With the increase of annual precipitation and the decline of average evaporation and average wind speed by the increase of farmland area,bad natural environment is improved in Yutian County.
