摘要
呼伦贝尔沙地是我国四大沙地之一,近年来由于自然因素加上人为不合理的活动,特别是过度放牧,使该沙地草场发生严重的退化、沙化,造成草场生产力的显著下降,制约畜牧业的健康发展。研究了沙地现状及扩展情况,分析了沙地形成的原因,由此提出治理呼伦贝尔沙地的主要措施以及合理利用草场的途径。
Hulunbeier Sand Land is one of the four main sandy areas of China. The last years, due to the natural factors and irrational human activities, especially over grazing, this sand pasture has been deteriorated and desertified severely. Consequently, not only the pasture productivity has been reduced, but also the development of livestock industry has been restricted seriously. This paper analyzed the cause of the sand land engendering and enlarging, at last brings forward the main measures about fathering Hulunbeier sand land and the method to use pasture resources ably reasonably.
