Zhagana Agriculture-Forestry-Animal Husbandry Composite System is a typical model of a complex mixture of agriculture, pasture farming and forestry. Within this system, farms, rivers, villagers, temples exist in great harmony with the surrounding forestry and grassland. The rivers come across from the grassland and forestry, whose bed can be used for crop farming. Local villagers will become herdsmen, farmers, hunters and woodcutters throughout the year according to the different seasons and farming calendar, giving full play to the role of agricultural production and ecological functions of this system.
