中文摘要	20002013年内蒙古风沙源治理工程区风蚀模数整体呈现下降趋势,风蚀程度有所减轻。5个亚治理区风蚀模数差异较大,其中浑善达克沙地治理区风蚀模数最高,其他依次为科尔沁沙地南缘治理区﹥乌兰察布高平原退化草原、荒漠草原治理区﹥锡林郭勒高平原-乌珠穆沁沙地盆地退化草原治理区﹥华北北部丘陵山地水源涵养治理区。工程区土壤风蚀量明显减少, 20012013年累计净减少1 370 446.65 * 10~4 t,其中,乌兰察布高平原退化草原、荒漠草原治理区累计净减少风蚀量最大;其次为锡林郭勒高平原-乌珠穆沁沙地盆地退化草原治理区。风力是造成内蒙古风沙源工程区土壤侵蚀的最主要营力。20002013年,工程区风蚀模数与风蚀量的逐步降低说明,京津风沙源治理工程实施十余年以来,通过实施各类治理措施,工程区土壤风蚀得到初步控制,工程区生态状况趋向好转,随着森林资源总量与质量的提高,水土流失状况进一步改善,沙化土地治理初见成效。
英文摘要	The wind erosion modulus in the area of Beijing-Tianjin sand source control project was in a downward trend during the period from 2000 to 2013,which means that the soil wind erosion was alleviated during that period. The wind erosion modulus in 5 divided sub-regions of the project area was very different from each other,in which it was the highest in the Otindag Sandy Land,and then it was in an order of the southern margin of Horqin Sandy Land > degenerated steppe and desert steppe in the Ulanqab Plateau > Xilingol Plateau-degenerated steppe in the basin of the Wuzhumuqin Sandy Land > Water Conservation Field at hilly and mountainous regions in the northern part of north China. During the period of 2001 - 2013,the amount of soil erosion was significantly reduced, its cumulative net reduction was 1370 446.65 * 10~4 t,in which the most significant reduction occurred in the degenerated steppe and desert steppe in the Ulanqab Plateau,and then in the Xilingol Plateau-degenerated steppe in the basin of the Wuzhumuqin Sandy Land. Wind was the main agent causing the sand erosion in the sand source project area in Inner Mongolia. The results of this study revealed that the ecological situation in the study area had been improved since implementing the Beijing-Tianjin sand source control project with the improvement of the total amount of forest resources and quality,and the soil erosion and desertification had been controlled to some extent.
