What are the characteristics and functions of terraces?

Terraced fields have always been the main way to use mountains in China, because it can not only use mountains, but also prevent soil erosion? After the development of past dynasties, the terraced fields in China have further developed and beautiful ancient terraced fields have emerged? Such as Hani Terrace in Honghe, Yunnan, Ziquejie Terrace in Hunan and Longji Terrace in Guangxi Zhuang Autonomous Region?

Hani Terrace in Honghe, Yunnan Province, also known as Yuanyang Terrace, is located at the southern foot of Ailao Mountain in Yuanyang County, Yunnan Province. It is a masterpiece left by generations of Hani people.

The terraced fields cultivated by Hani people in Yuanyang change with the mountain situation and adapt to local conditions. Farmland will be cultivated when the slope is gentle, farmland will be cultivated when the slope is steep, and even the stone cracks under the ditch will be cultivated. Therefore, there are several acres of terraces, and the small ones are only as big as dustpans, and often there are thousands of acres on a slope.

After decades of life-long efforts, the Hani people have cultivated thousands of terraced fields and introduced ditches into the fields for irrigation. Because mountains and rivers flow all the year round, terraces can be full of water all the year round to ensure the development and harvest of rice?

Hunan Ziquejie Terrace is located in the western mountainous area of Xinhua County, Loudi City, Hunan Province. Terraces around 1.300 hectares. It is the best in the world because of its high terrain, large scale and beautiful shape.
