摘要: 辽西北地区的彰武县、康平县、法库县土地沙漠化严重，其发育类型可划分为内陆沙漠化土地和沿河沙漠化土地2种.基于对辽西北地区土地沙漠化现状的分析，认为地形地貌、地层岩性、气象及水文条件是导致土地沙漠化的自然因素；超载过牧、盲目农垦是加剧土地沙漠化的人为因素.提出了退耕还林还草、科学管理治沙、建立多渠道投入机制、适当移民、加强法治宣传等防治对策建议.

Abstract: The northwest region in Liaoning Province, covering Zhangwu, Kangping and Faku counties, suffers serious land desertification, which involves inland desertification and river bank desertification. Study on the current situation of the desertification in Northwestern Liaoning shows that the natural factors for the desertification include landform, stratum and lithology, meteorological and hydrological conditions, while the human factors involve overload pasture and improperly cultivation. The countermeasures to prevent and control the desertification are returning farmland to forest and grassland, scientifically controlling the sand and appropriate emigration.
