- Abstract:
-
In order to systematically understand the ecological effects, especially effect of grazing and fencing on soil and water conservation of vegetation in grassland in the northern sandy region, a large number of literature was collected and screened to explore the effects of grazing intensity, grazing period and fencing period on above-ground biomass and vegetation coverage in typical steppe and desert steppe by using meta-analysis. The results indicated that:(1)in both desert steppe and typical steppe, the relative aboveground biomass and relative vegetation coverage decreased substantially with the increase of grazing intensity;(2)the negative effect of grazing period on the relative aboveground biomass was very significant;(3)in both desert steppe and typical steppe, the aboveground biomass and vegetation coverage increased greatly as the fencing period increased. To sum up, grazing and fencing are important factors affecting the ecological benefits of vegetation in the northern sandstorm area. In addition, more attention should be paid to the effects of grazing and fencing on the ecological benefits of soil and water conservation, so as to comprehensively analyze the ecological benefits of soil and water conservation and provide technical support for soil and water conservation in this region.
