Degradation Mechanism and Applicability of Irrigation Recovery Technique on Xilamuren Grassland, Inner Mongolia

Abstract:

Due to the drought climate and over grazing, the grassland degrades severely recently, which not only influences local environment, but also threatens ecology safety of northern areas. Urgently control of degraded grassland and prevent advanced deterioration are needed. Recently, irrigation plays vital role on the recovery of degraded grassland in northern pastoral areas. Different amount irrigation experiment (adequate and moderate irrigation) was carried out from 2007 to 2009 on Xilamuren Grassland, Inner Mongolia. The experiment plots vegetation quantitative characteristics were investigated during 2007～2011. Compared with no irrigation plot, it’s concluded that: ① Different irrigation amount have the same effect on improving the production and biodiversity during irrigation. ② When stopped irrigation, the production and biodiversity of the two ever irrigated plots degraded more and faster than the non irrigation plot equally. ③ Moderate irrigation can save more water while recovering degraded grassland satisfactorily. To keep stable, the irrigation amount and times should be decreased gradually.
