| 摘 要： | 杜尔伯特蒙古族自治县是松嫩沙地沙漠化面积最大的县,他拉哈镇是该县沙漠化比较有代表性的地区。土地沙漠化分布在全镇各村屯,面积为109.91 km2,占全镇土地总面积22.95%,主要为轻度和中度沙漠化类型。在沙地的沙丘中普遍发育1~2层古土壤层,经14C测年为(4 197±383)a BP～(7 463±143)a BP。经孢粉分析,草本植物花粉较多,乔、灌木植物花粉较少,古土壤层属全新世大暖期时期形成。沙地沙漠化的成因,既有自然因素又有人为原因。对中度沙漠化土地（包括沙丘地）一般采取疏林、灌、草治理模式;对轻度沙漠化土地（含沙平地）采取林、果、药（草）、杂（小杂粮）治理模式。
