Results indicated that the percentages of the area of grassland, woodland, basic farmland and orchard to the total productive land area were 44%, 22%, 20% and 14% respectively according to this new land use scenario. Based on the datasets of 197 counties in the Loess Plateau, the estimated forage potential would amount to 104 881 028 ton/a (hay), which can raise 104 881 028 productivity sheep unit/ a. According to the unchanged price in 1999, pastoral gross product value would amount to 52 440.51 million yuan RMB/a, which is as much as 5.3 times of that in 1999 and exceeds the agricultural gross product in 1999 by 14%. In addition, there are ca. 59% of counties whose mean pastoral product value per person would be more than 1 000 yuan RMB/a, while ca. 41% of counties whose mean pastoral product value per person would be less than 1 000 yuan RMB/a. On the other hand, the estimated agricultural gross product on the Loess Plateau would amount to 11 472 2.34 million yuan RMB/a and ca. 46% of the total would come from pastoral industry, 27% from orchid industry, 14% from forestry and 13% from farmland. From the perspective both ecologically and economically, this paper holds that the herbi-vore-based pastoral industry is a promising industry bolstering the ecological improvement and economical development on the Loess Plateau.展开更多
