Abstract: By the method of ecological footprint (EF), an EF model of farming industry was established to calculate the EF of farming industry in Shenyang region in 2001-2006, and to analyze the change patterns and causes of the EF per unit weight agricultural product (EFunit). In 2001-2006, the EF of farming industry in Shenyang region increased after an initial decrease, while the EF unit had a decreasing trend. Cropland EF was the main component of the EF, followed by water EF, and energy EF. The cropland EF decreased from 56.8% in 2001 to 54.4% in 2006, water EF fluctuated between 27.6% and 32.1%, and energy EF increased from 14.0% to 16.2%. The growth of per unit agricultural product was accompanied with the increase of the inputs of potash fertilizer, compound fertilizer, pesticides, and agriculture-used film, steel, and diesel. All the results indicated that in recent years, the dependence of farming industry in Shenyang region to fossil energy was increasing.
