土地利用/覆盖变化研究方法

A Review on Methods of Land-use and Land-cover Change

土地利用/覆盖变化是导致地球表层系统景观变化的主要因素,人类通过对与土地相关的自然资源的开发和利用,对生态环境产生重要影响.围绕土地变化科学3个热点问题——土地利用/覆盖变化监测、驱动力和模型的研究方法进行说明和评述.在简要介绍土地利用/土地覆盖研究概况和发展趋势的基础上,分别阐述了土地利用/覆盖变化监测方法、土地利用/覆盖变化研究的统计方法和土地利用/覆盖变化模型研究方法,最后对土地利用/覆盖变化方法研究做了展望.近十几年,虽然土地变化科学在理论和方法方面取得了较快的发展,但仍需要更多的研究和新的方法来丰富和完善土地变化科学.

Land-use and Land-cover change （LUCC） is one of the most profound human-induced modifications of the Earth＇s system, which is a complex process caused by the interaction between natural and human social systems occurring over a wide range of temporal and spatial scales. Pro- gress of LUCC was described firstly, then several research methods of 3 hot spots of LUCC were ex- patiated, for example, methods for monitoring, land use driving forces and modeling. Finally, the de- velopment trends of the methods of LUCC were forecasted. Although the land change science has made a huge leap,it still need more researches and new methods to improve the theoretical frame- work of land change science.
