| Abstract: | The conservation of the potential productivity of farmland on hillside represents the ultimate target in the efforts of environmental construction and a key link in environment management. The authors estimated the potential productivity of the fields on sloping land of purple soil in Fuling, Chongqing and analyzed the factors influencing it. The results showed that the primary limiting factor was soil water. The techniques of hedge-row planting and miniature water conservancy on sloping fields are recommended for wide extension in this region for water and soil conservation. |
