| Abstract: | The secondary bare land is one kind of special natural landscape which in the ecosystem degeneration process forms,forms the main actuation factor and the landscape characteristic according to it is different,the Maqu County secondary bare land may divide into the desertification secondary bare land,black soil beach the secondary bare land,the salination secondary bare land,to move abandons the herd to occupy,to abandon the herd road,the mining area and the road along the route,has carried on the discussion to its origin and the characteristic,then the formulation corresponding science reasonable ecology repair pattern,provides the better theory basis and the technical support for this region degeneration ecosystem repair and the reconstruction. |
