我国土地利用/土地覆盖变化研究的特点和问题

Analysis on Characteristics and Problems of Researches on Land Use and Land Cover Change in China

我国土地利用/土地覆盖变化的研究自20世纪90年代起发展至今共分为3个阶段,包括理论研究起步阶段、理论应用于实践的快速发展阶段和不断发展与完善阶段。笔者拟从3个不同的发展阶段分析其研究的特点及其存在问题,并对未来我国土地利用/土地覆盖变化研究进行展望。研究结果表明:我国土地利用/土地覆盖变化不论是在时空变化研究、驱动机制研究还是生态环境效应研究和模型模拟研究中都取得较大进步,但在研究过程中未能区分气候变化与人类活动对土地利用变化的影响作用。

Researches about land use/land cover change in China could be devided into three stages since 1990s’ including initial stage of theo-retical research,rapid development stage of applying theories to practice and continuous development and improvement stage.The characteristics and existing problems in researches were analyzed from 3 development stages,researches on land use/land cover change in China in the future were forecasted.The results showed that great progress were obtained in research on temporal and spatial change,driving mechanism,ecological environment effect and model simulation.However,both the distinction of influences on land use change between climatic variation and human ac-tivities failed to involve in course of study.
