土地利用/土地覆盖变化的研究方法

文章从LUCC计划研究的主要内容入手，探讨了其相应的研究方法，提出了我国LUCC研究的新思路：(1)从研究的空间尺度来看，应遵循“先局部、再整体；既分工、又合作”的研究思路；(2)从研究的时间尺度来看，应遵循“聚焦近期、兼顾历史、瞄准未来”的研究思路，用考古等研究方法重现5000多年来各个时期的土地利用与土地覆盖状况，建立与竺可桢先生建立的5000年以来的气候变化序列相匹配的LUCC变化序列；(3)从研究的技术手段来看，应注意多源信息的复合使用，重视新技术(尤其是3S技术的集成使用)的运用；(4)开展跨学科研究；(5)结合国家建设与发展需要开展研究；(6)加强理论集成研究。

Discussion of the Research Method on Land Use/Land Cover Change

Being the main cause and the vital issue in the global environment change and sustainable development disciplines, studies on land use/land cover change (LUCC) has gained increasing attention in China. Many people have studied China's land use and land cover change from their major field, and have made a great progress. However, in general, their research still stay the stage of tracing the development of foreign advanced studies, and keeping up with the foreign partner by imitating their methods. There are many reasons for this, but the main one is the lack of suitable research method. This paper discussed the optical research methods in China based on the analyses of the contents of the LUCC, and proposed some new ideas on how to research LUCC in China.
