摘要:
沙漠化作为当今最重要的环境与社会经济问题困扰着世界,威胁着人类的生存与发展.我国是世界上受沙漠化危害最严重的国家之一,对呼伦贝尔沙地的沙漠化的原因进行分析,找出导致沙漠化的的原因是由于在气候环境恶化的情况下人口压力的增大引起的过度砍伐、开垦、放牧、采挖等不合理利用森林和草原资源和生产建设活动从而使固定沙地活化,使该区沙漠化土地扩张.在最后提出尽快恢复退化草地的植被是治理沙漠化的关键.
Abstract:
Nowdays,desertification has been perplexing with environment and social economy in the world.It is threatening to maintain mankind’s existence and development.China is one of the countries of the most serious desertification in the world.Desertification causes of Hulunbeier sand-land are analyzed and it indicates that excessive logging,cultivation,grazing,dredging,other unwarranted use of forest and grassland resources,production construction activities resulted to the desertification and extended desertification land.At last,it is proposed that the key of control desertification is recovering vegetation of deteriorated grassland as quickly as possible.
