Abstract:: Driven by agricultural structure regulation and ecological de-farming policy,the land use of the Loess Plateau has tempestuously changed since 1990,and the change has a biggish influence on agricultural development.Taking Baota district and Ansai county located in the middle Loess Plateau as a study case and using the data of land use survey in 1992-2000,farmer household spot check in 2004 and statistical data,this paper quantitatively analyzed the influences of land use change on grain and fruit production,forestry and stockbreeding.As a result,the paper found:①The standing decrease of cultivated farm area induced the loss of grain products,and the loss of an abundant year is obviously more than that of a drought year.②Following the growth of garden plot area,an amount of fruit product mounted up at all times.③Protection forestry mainly included rearing seedling,tree-planting and forest management.④The inherent relation between forest-grass land change and stock raising development was severed by limited graze policy,and the policy severely restricted the development of keeping sheep in Baota district and Ansai county.
