内蒙古自治区地域辽阔,总土地面积为118.3万平方公里,自然资源十分丰富。就森林资源而言,全区现有森林面积23,443万亩,其中原始林10,674万亩,天然次生林11,208万亩,人工林2587万亩。虽然富绕,但其分布极不均匀,70％的森林资源分布在大兴安岭北部山地,其它广大地区则缺林少树。全区森林覆盖率为13.21％,而西北地区的高原、丘陵和平原仅为0.16—4.1％,农牧业生产基地森林覆盖率低,生态系统十分脆弱,抵抗自然灾害能力很低。目前还存在着向恶化生态环境发展的趋势,平均每年沙漠化面积增加550万亩。这种现状不能不引起我们的重视。
The vast territory of Inner Mongolia Autonomous Region, with a total land area of 1.183 million square kilometers, is rich in natural resources. As far as forest resources are concerned, the existing forest area in the region is 234.4 million mu, of which 106.74 million are virgin forests, 11.28 million mu of natural secondary forests and 25.87 million mu of plantations. Although rich, but its distribution is extremely uneven, 70% of the forest resources are distributed in the northern mountains of Daxinganling, the vast majority of other areas are less than trees. The forest coverage in the region is 13.21%, while the plateau, hills and plains in Northwest China are only 0.16-4.1%. The forest coverage in farming and animal husbandry production bases is low, the ecosystem is very fragile, and the ability to resist natural disasters is very low. At present, there is still a tendency to worsen the ecological environment, with an average annual increase of 5.5 million mu of desertification area. This situation can not but cause our attention.
