今年对呼伦贝尔草原生态来说,依然是个喜忧参半的年头。丰沛的雨水让广阔的草原草木丛生,但是短暂的天恩也掩盖了草原生态背后深刻的矛盾。但就在水草丰美的草原背后,2005年内蒙古自治区荒漠化监测结果表明:呼伦贝尔沙地、沙丘活化,植被盖度降低,风蚀坑大量出现,流动沙地增加,5年间沙化土地面积增加1.84万亩,流动和半固定沙地增加了27.3万亩,呼伦贝尔草原的土地生产力仍呈下降趋势。
This year is still a mixed year for Hulunbuir grassland ecology. The abundance of rain makes the vast grasslands lush, but the short grace also masks the profound contradictions behind the grassland ecology. However, just behind the grassy grassland in the grassland, the monitoring results of desertification in Inner Mongolia Autonomous Region in 2005 showed that: the Hulunbeier sand land, the sand dunes and the vegetation coverage decreased, the wind erosion pits appeared in large numbers and the mobile sand land increased. The area of desertified land increased by 18,400 mu, The flow and semi-fixed sand area increased by 273,000 mu, while the land productivity of the Hulunbeier grassland continued to decline.
