论土地利用与覆盖变化相关领域及其研究态势

ON THE CHANGES AND THE RELATIVE FIELDS OF LAND UTILIZATION AND LAND COVER AND THEIR RESEARCH SITUATION

土地利用/覆盖变化是全球变化的重要驱动因子,与遥感及对地观测技术、数字地球及地球系统科学等相关研究领域关系密切。其研究目标是探索土地利用与土地覆盖在不同时空尺度上的相互作用及其变化,为实施可持续发展战略提供决策依据。主要研究内容有土地利用/覆盖变化驱动因子、土地可持续管理模式以及土地利用/覆盖变化与全球变化的相互作用机理等。目前,土地利用/覆盖变化研究已经取得了一些进展,从而推动了全球变化研究。

The changes of land utilization and land cover are the important driving factors, which have the close relation to remote sensing, air-to-land observation technology, the digital earth and the earth system science and some other interrelated research fields, the research goals of which are to probe the interaction and changes between land utilization and land cover at different time and space, providing the basis of policy decision for the sustained development strategy, the leading research contents of which are as follows: the driving factors of land utilization and land cover, sustained land managing model and interaction mechanism between land utilization or land cover and the earth changes. At present, some research progress of land utilization and cover has beon made so as to push the change researches of the earth.
