区域土地利用转型与土地整理

目前,我国城市土地利用结构远未达到优化的水平,农业土地利用的规模不经济等土地利用问题都可通过土地整理加以解决,我国未来土地管理的任务会更多的在土地整理方面。我国土地整理的根本任务是形成合理、高效、集约的土地利用结构,增加有效耕地面积,提高土地利用效率,适应社会经济发展对土地的需求。我国地域辽阔,社会经济发展程度存在明显的区域差异,正是因为社会经济发展程度的这种区域差异,它将导致在同一时段内含有不同的土地利用转型阶段。大多数区域的土地利用形态都要经历一些发展阶段,即经过一段时期的持续变化后,直至与其它类型之间达到一个新的平衡。因此,有关部门在制定有关土地整理的目标、模式及政策的过程中,也要充分考虑待整理区所处的土地利用转型阶段,因为在通常情况下这些阶段是区域发展进程中必须要经历的。然而,通过实施土地整理,调整用地结构,可加快社会经济的发展,促使区域土地利用转型阶段的转变,同时它也会向土地整理提出新的更高层次的要求,以实现土地资源的可持续利用。

Land Rehabilitation and Regional Land Use Transition

Land use/cover changes (LUCC) are not simple process There are complex simultaneous patterns of land cover change, ranging from modifications in land cover to conversions and maintenance To avoid the unilateralism of LUCC research, it is necessary to continuously put forward new themes, develop new methods and find new integrated approach Especially, concerning research on LUCC should pay more attention to the actual conditions in China and aim at the new demands of society Land use transition is a new research theme for LUCC, and land rehabilitation is a new thing in China The interaction and relationship between land use transition and land rehabilitation are discussed in this paper for the purpose of primely carrying out land rehabilitation and realizing sustainable land use At present, a lot of land use issues in China can be solved through carrying out land rehabilitation In the future, the tasks of land management will pay more attention to it The objectives of land rehabilitation in China are to form a rational, effective, and intensive land use pattern, increase effective area of cultivated land, enhance land use efficiency, and meet the demands of socioeconomic development to land It would change with the changes of the socioeconomic development phase that the country/region is in Regional land use morphology is the overall pattern of actual land cover in a region at a given time, comprising main types of land use Regional land use transition refers to the changes in regional land use morphology over time, and it usually corresponds to the transition of socioeconomic development phase In China, there are different land use transition phases in the same period of time as a result of the differences of regional socioeconomic development levels and physical conditions Therefore, in the process of laying out concrete objectives, modes and policies of land rehabilitation in a region, it is suggested to take regional land use transition phase into accountant Simultaneously, the course of socioeconomic development in a region can be accelerated through carrying out land rehabilitation and adjusting land use structure, which can also promote the transformation of regional land use transition phases and put forward new requirement for land rehabilitation.
