| Abstract: | The cultivated slope lands are distributed mainly over central and West China's fragile ecological zone. The soil and water loss of the cultivated slope land is the main types of soil erosion in central and West China's fragile ecological zone. Terracing of the land on the slope is the basic measures to prevent soil and water loss of the slope cultivated land and bring about a sustainable utilization of the cultivated slope land. Our government should invest more money to terrace the cultivated slope land. |
