| Abstract: | The paper, according to the natural environment conditions such as water-heat and soil etc. and the need of restoring the ecological environment, divides Baiyin prefecture into five zones such as cold temperate-feeble wet, cold temperate-feeble drought, feeble temperate-feeble drought, feeble temperatedrought, feeble temperate-ultradrought zone and ten subzones of biological climate and for ecological restoration. The approach to restore the zonal ecology was probed according to the basic characteristics, current status of degradation and the major degradation factors of each restoration zone. |
