内蒙古自治区的荒漠化土地

本文根据《联合国防治荒漠化公约》的规定,依据《全国荒漠化监测主要技术规定》,区划界定了内蒙古荒漠化潜在发生的范围,并对内蒙古的土地荒漠化状况进行了宏观监测。监测工作中充分利用了“3S”技术,现地调查与遥感解译相结合获取地面信息,利用数理统计的原理计算各类荒漠化土地面积并进行了程度分级。同时在弄清《联合国防治荒漠化公约》限定范围的土地退化的基础上,调查了《联合国防治荒漠化公约》范围外的土地退化情况。结果表明内蒙古自治区土地荒漠化面积为74.39×104km2(约合11.16亿亩),占自治区总面积118.3×104km2的62.88%,为区域生态环境建设和规划提供了依据。

Desertified Land of Inner Mongolia Autonomous Region

In accordance with the regulations of The Agreement of UN Convention to Combat Desertification, based on the Major Technical Rules of the State Desert Supervision, the article rules out the potential areas of desertification in Inner Mongolia Autonomous Region, and monitors generally the situation of desertification of Inner Mongolia. In the process of monitoring, the technique of "3S"(GIS/RS/GPS) is fully used, and a site survey and a remote interpretation are used integrally. Moreover, the desertification degrees are determined by using mathematics and physics statistics. At the same time, based on making sure of the desertification range ruled out by the Agreement of UN Desert Control, the article also surveys the desertification situation that is out of the range. The survey result shows that the desertified area in Inner Mongolia is 74.39×10 4km 2 (approximately 1.116 billion mu), accounting for 62.88% of the total area of 118.3×10 4km 2, so as to refer the construction and planning of ecological environment in the region.
