Grassland Deterioration and Fixed-Grazing:Comparative Study on Ordos Grassland and Bashang Prairie
摘要
Abstract
Grassland degradation and desertification are conceptually different, grassland degradation is caused by interaction of irrational human activities and fragile ecological environment, and it can turn into desertification. Two northern regions:Ordos’s grassland and Bashang prairie were selected as typical objects of the study, both of which occurred degradation. From the natural mechanism level, natural climate, rainfall, soil, vegetation, incidental natural and biological disasters were reason which led to degradation. Grassland degradation in Ordos’s grassland and Bashang prairie performed consistent human reasons, for instance:irrational land reclamation, overgrazing, firewood collection and over-excavation of Chinese herbal medicines, irrational tourism resources development and excessive urban construction. Degradation mechanism manifests in this way: natural factors determined the fragility of the natural environment, worse still, human factors further influenced the vulnerability of the natural environment, this had led to grassland degradation, created a feedback loop with human systems, further reacted in natural systems. Therefore, based on grassland degradation succession law, in order to realize sustainable development of grassland animal husbandry, regulations named‘decide livestock quantity according to grass resource’and‘drag a balance between grassland and livestock’must be implemented. What’s more, rotation grazing, rest grazing and prohibition of grazing should also be carried out.关键词
