Terrace is a special form of farmland, and its appearance is closely related to human awareness of land use and ecological protection. The construction history of terraced fields can be traced back to ancient times, originally for the development and utilization of sloping fields and other unsuitable land resources. With the growth of population and the development of agricultural technology, terraced fields have gradually expanded to flat land suitable for planting and become an important agricultural farming method.
The advantage of terraced fields is that they can effectively prevent soil erosion and improve land utilization and crop yield. By building terraces, sloping fields can be transformed into farmland suitable for planting, the cultivated land area can be increased, and the yield and quality of crops can be improved. In addition, terraced fields can also improve soil quality, increase soil organic matter content, improve soil water retention capacity and fertility, and further promote crop growth and development.
Terraces are not only used in agricultural production, but also have high ecological protection value. By building terraces, soil erosion and sediment deposition can be reduced, the health of water sources and rivers can be protected, and ecological balance can be maintained.
The role of terraces:
1. Prevention of soil erosion: Terraces are built along hillsides, and transforming sloping fields into terraced farmland can effectively prevent soil erosion. In rainy season, terraced fields can intercept water flow, reduce soil erosion and sediment deposition, and protect soil resources and ecological environment.
2. Improve land utilization rate and crop yield: The construction of terraced fields can transform originally unusable sloping fields into farmland suitable for planting, thus increasing the cultivated land area. At the same time, because the terraces are similar in shape to steps, they are beneficial to water storage, irrigation and drainage, and can improve soil water-holding capacity and fertility, promote crop growth and development, and improve crop yield and quality.
3. Improving rural ecological environment: Terrace construction can not only improve soil quality and increase crop yield, but also improve rural ecological environment, promote tourism development and increase farmers' income.
The change of the shape and color of terraced fields can increase the aesthetic feeling of agricultural landscape, attract tourists to watch and travel, and promote the development of local economy. At the same time, because the construction of terraces requires a lot of manpower and material resources, it can provide employment opportunities for local farmers and increase income sources.
