HUMAN DISTURBANCE AND ECOLOGICAL MANAGEMENT ON FOREST STEPPE ECOTONE IN EASTERN HUN SHANDAKE SANDY LAND

开垦土地、过度放牧、机动车辆毁地和旅游等人为活动给浑善达克沙地东部的森林—草原交错带造成了一系列环境问题，像草场退化、土地沙化、野生动植物资源枯竭等。为了使森林—草原交错带的土地资源可持续利用，采取措施保护森林—草原交错带的土地资源并对退化沙化的土地进行整治和恢复是十分必要的。

Human activities such as reclamation, overgrazing, vehicle damaging land and tourism result in a series of ecological problems,e g.range deterioration,desertification and exhaustion of wild animals and plants, in the forest steppe ecotone of eastern Hunshandake sandy land.
