中国土地利用/覆被变化研究的现状与问题

The Advances and Problems of Land Use and Land Cover Change Research in China

土地利用 /覆被变化是全球变化的重要组成部分和原因 ,因而是全球变化领域中重要的研究方向之一。本文在评述了中国土地利用 /覆被变化研究的现状、取得的进展及存在问题的基础上 ,提出应把土地利用 /覆被变化研究的理论体系、不同空间尺度的土地利用 /覆被变化的动态模型、土地利用 /覆被变化与全球环境变化和可持续发展之间的关系作为重点加以研究 ,以提高中国土地利用 /覆被变化的研究水平。

Land use and land cover change (LUCC) is one of the important focuses in the area of global change research because it is not only the significant component but also the major reason of global change. Some results of LUCC research, such as causes, driving forces, LUCC modeling and effects on environment, have been reported in China, but many aspects need to be further studied, compared with international research on it. Based on reviewing them, this paper presents that the following contents should be emphasized and put priority in LUCC study in the coming period of time. (1) The united theory system of LUCC research. (2) More advanced and dynamic LUCC models of various scale of spatiality which should include data processing and better understanding the interaction of LUCC and driving forces. (3) Relations between LUCC and global change or sustainable development, especially to pay more attention to local and regional effects on environment.
