(1) Abundant natural grassland resources According to reports, there are approximately 400 million hectares of natural grassland in China. There are more than 5,000 varieties of natural forage grasses with abundant forage, which has the unique advantage of developing the sheep industry. While China produces grain every year, it can also produce 570 million tons of crop stalks, which provides basic material conditions for the development of mountain mutton sheep. China's per capita arable land and per capita food are small. Therefore, the development of the mountain mutton sheep industry has important strategic significance for saving feed grain, resolving the contradiction between humans, animals and grain, increasing the income of peasants, and promoting poverty alleviation for mountain farmers. (2) Labor-rich mountainous areas The mountainous population accounts for more than half of the country's total population, and there is a common phenomenon that there are more people in the mountainous areas in rural areas. Except for some laborers working outside, there are more idle workers. Therefore, it is of great practical significance to develop the sheep industry in the mountainous areas, fully develop and utilize labor resources, do a good job in the employment of mountain farmers, improve the living standards of farmers in mountain areas, and promote the balanced development of economic development in the poverty-stricken mountainous areas. At the same time, the development of sheep meat production in the mountainous areas has solved some of the rural surplus rural labor transfer work. (3) The mountainous area has a beautiful environment and fresh air. The mountainous area has a beautiful environment and fresh air. It provides the most basic guarantee for the production of pure natural, non-polluting and nutritious safe lamb products. At the same time, lamb is a green food, but also a nutritious delicacy, has always been favored by consumers, the market demand is large, the price increased year by year. (4) The climate in the mountain area is suitable for the temperature of sheep in mountainous areas, which is lower in the summer than in the plains but higher in the winter than in the plains. This will result in fewer opportunities for intense heat and cold, and weaker intensity, which will help the sheep to survive winters and will also benefit crop growth. Precipitation resources in the mountains are also richer than the plains, especially from July to August each year. It is a dry season in the Yangtze River valley, and it is just the season of crop growth. However, the cost of land in mountainous areas is relatively low, and it is possible to adopt the mode of planting grass and raising sheep to develop mountain sheep production.
