A review upon the importance and effect of piling soil to ridge with non-tillage for agro-ecosystem in central hilly area of Sichuan Basin

The structure and function of agro-ecosystem in central hilly area of Sichuan Basin were expatiated to indicate the dry land sub-ecosystem is an exploitation system with the highest potential and most problems. A view was reached that the system of piling soil to ridge with non-tillage (PSRNT) is a important technique support for resuming constructing fine ecosystem for dry land in the area, after expounding the function features, exploitation and conservation mechanism of the PSRNT. Moreover, the issues and application prospects of PSRNT were pointed out to cause the concerns of next step research.
