近70年来中国历史时期土地利用/覆被变化研究的主要进展

Main Progress in Historical Land Use and Land Cover Change in China during the Past 70 Years

历史时期土地利用/覆被变化是当前全球变化研究的重要组成部分。中国拥有丰富的历史文献资料,在历史时期土地利用/覆被变化研究领域具有明显优势,并在近70年取得了丰硕的研究成果。本文从历史土地垦殖与林草地变迁过程、历史LUCC数量重建和历史LUCC空间重建等3个方面,简要回顾了中国历史时期土地利用/覆被变化研究所取得的主要进展,阐述了其由定性、半定量研究走向"三定"(定时、定量、定位)研究的时代背景及发展历程。并在此基础上,展望该领域未来研究的重点与方向。

Historical land use and land cover change(LUCC) is a significant component of the current global change research. As an ancient civilization with a long history, China has rich historical document, thus, it has an obvious advantage in historical LUCC research in the global world. Over the past 70 years, Chinese historical LUCC research has achieved fruitful results. In this paper, the progress of historical LUCC research in China is reviewed from three main aspects: the historical change process of land reclamation and forest and grassland cover;quantity reconstruction of historical LUCC;spatial pattern reconstruction of historical LUCC. And the historical background and development progress of Chinese historical LUCC research from qualitative research to timing, quantification, and positioning research is also elaborated. On this basis, a perspective analysis on the research emphasis and direction in the future is made.
