土地利用与覆被变化研究进展及其在荒漠化地区的研究前景
首发时间:2013-03-01
摘要:随着人类活动的日益增强,土地资源受到强烈干扰,引起明显而巨大的土地利用与覆被变化(Land-use and land-cover change, LUCC)。目前的研究显示,土地利用与覆被变化可以通过累积性的方式对全球变化造成影响,因此人类对土地利用方式的改变是驱动全球变化的一个主要因素,所以关于LUCC的研究成为当前全球变化研究领域中的一个热点。本文通过综述分析土地利用结构、格局及其变化过程,土地利用变化的驱动机制与模型,土地利用变化的效应究,土地利用系统等方面的研究,为荒漠化地区相关研究的开展提供参考。

The Land-Use and Land-Cover Change Research Advance and Its Research Trend in Desertification Region
Abstract:With the increasing human activities, land resources are subject to intense interference, which caused the obviously huge land-use and land-cover change (LUCC). The present study shows that global change can be impacted by land use and land cover change through a cumulative way. Therefore, the change in land use patterns by human is one of the main factors driving global change. As a result, the LUCC research has became a hot topic in the current global change research areas. This paper summarized the land use structure、pattern and process of change, the drive mechanism and models of land-use change, the effects of land-use change, the study of the land-use system, etc, which can provide a reference for the development of LUCC research in desertification area.
Keywords: Land use and information technology Land-use and land-cover change Global change desertification
