| The west development of China has been a great strategy of Chinese government. Although the arid area of north-west China is a large agricultural region which is rich in resources, but ecological environment is very poor and the conflict between economic development and environment protection become more and more severe. After returning farmland into forest and grassland, how the farmer can develop in a sustainable manner is a big problem for the government to face up. This paper analyzes the main problems of agricultural development in the southern area of Ningxia province, summarizes the 20-year experiences of the experimental zone in the area, and puts forward four different models of eco-agriculture, fruit-vegetable model, fruit-seedling model, grass-fruit-livestock. The economic and social return is also analyzed, so as to set up the basis of returning farmland into forest and grassland. |
