内蒙古自治区大青山北部丘陵区,东起锡盟多伦县,西刊巴盟乌拉特后旗,共有耕地1952万亩,其中旱地1745万亩,约占总耕地面积90％,且大部分属于旱坡地。本区曾是自治区重要的粮、油产区,但耕作粗放,粮食产量低而不稳。究其原因,除了自然条件本身恶劣外,主要是土地的不合理利用,加剧了风蚀水蚀,使土壤严重沙化。风蚀、水蚀是造成农田生态环境恶化的主要因素。
Inner Mongolia autonomous region Daqingshan northern hilly area, Xidan Duolun County in the east, West Patch Wulatehouqi, a total of 1952 mu of arable land, of which 1745 mu of dry land, accounting for about 90% of the total arable land, and most of the drought Slope. This area was once an important grain and oil-producing area in the autonomous region, but the extensive farming and low and unstable grain output. The reason, in addition to its poor natural conditions, the main reason is the irrational use of land, aggravating the erosion of wind erosion, the soil serious sandification. Wind erosion and water erosion are the main factors that cause the deterioration of farmland ecological environment.
