摘　　要：由于自然和人为原因,在半干旱的辽西北地区,存在较为严重的土地沙漠化问题。沙漠化土地的科学利用已成为目前关注的重点之一。但在实际的研究过程中逐渐认识到,沙漠化土地不能单纯地为了治理而治理,需在土地利用的动态过程中得到不断"治理"。已有的文献大多围绕土地沙化原因和治理措施论述,而对沙漠化土地科学持续利用的模式探索较少。试图通过阐述辽西北土地雁行利用模式、土地需水利用模式、土地整理利用模式、保护性耕作利用模式和沙产业利用模式,达到在土地利用的过程中使沙化土地得以治理的目的,为"突破辽西北"战略的实施和实践提供重要的自然环境基础。Because of natural and artificial reasons,there existed serious land desertification in the arid Northwest of Liaoning.The scientific utilization on sandy land has been one of the research hot spots at present.It has been recognized that land desertification can not be controlled simply,but should be managed in the dynamic process of land utilization.Most of literatures have only discussed the reason and action on desertification,but little attention has paid to the model of sandy land use.The land use modes,including echelon,water requiring,land consolidation,conservation tillage and sand industry,have been explored in detail,in order to control desertification and promote the implementing and practicing of strategy about ＂breaking through the northwest of Liaoning＂.
