内蒙古北部荒漠草原带的严重荒漠化及其治理

位居干旱气候区的内蒙古高原中北部的荒漠草原地带 ,面临着严重荒漠化的威胁。目前已有 90 %以上的天然草场退化与沙化 ,变成寸草不生的不毛之地。大大扩展了我国北部沙尘暴频繁发生的地带 ,成为北方生态安全最危险的地区。这是多年来盲目增畜 ,超载过牧 ,滥垦乱挖的掠夺式生产经营中又加上干旱气候因素的耦合作用所造成的必然恶果。面对这一严峻形势 ,急需采取果断措施抢救荒漠草原地带的整体生态环境。应立即实行禁牧封育 ,人畜转移 ,调整结构 ,移民扩镇。使荒漠草原地带与农牧交错地带以及城市之间建立起产业化可持续发展的新途径

Serious Desertification of Desert Steppe Zone and Its Control in Northern Inner Mongolia

The desert steppe zone in the arid land of northern Inner Mongolia plateau is confronted with serious desertification. Now, over 90% of the rangeland has been degraded and becoming to desert, which enlarge the sand-dust storm occurence area in this region, and made the region becoming one of the most dangerous areas that threaten the eco-evironment of northern China. Such severe consequences were caused by plunderful production and management, such as excessive grazing? unresonable cultivation and digging, as well as droughty climate. To solved the problems, the paper put forword the measures, such as prohibiting grazing? moving the people and livestock to other places? regulating the economic structure and enhancing the urban construction. This may help to establish a sustainable development of industrialization among the desert steppe zone? farming-pastoral zone and urban in the region.
