基于3S技术的珠江三角洲景观格局动态变化述评

珠三角是一个景观格局与过程变化极为复杂的区域,近30年来,高速的经济增长与快速的城市化过程使珠三角的景观发生了剧烈的变化,随着全世界对生态环境发展的重视,该区域的景观变化研究也引起了众多专家和学者的关注.另外,随着遥感(RS)、地理信息系统(GIS) 和全球定位系统(GPS)技术的发展和成熟,基于3S技术联合来监测和研究景观格局及其变化也成为研究的主流.因此,基于3S技术对珠江三角洲景观格局动态变化进行了大量的研究,并取得了一些成果.本文首先总结了基于3S技术监测景观格局动态变化;其次分析了这些方法在珠江三角洲地区中的应用;并提出几点展望,旨在为珠三角今后的景观格局变化监测研究提供一些必要的借鉴和支持.

Review on landscape pattern change of the Pearl River Delta based on 3S technology

Landscape pattern and its change in the Pearl River Delta (PRD) are very complicated. Especially, within three decades of reform and opening-up, the landscape pattern of the PRD has changed with rapid economic growth and urbanization process. With an increasing concern to development of ecological environment, greater attention of many scholars and researchers is being paid to investigating change of ecological landscape in the PRD. In addition, with the rapid development of remote sensing (RS), geographic information system (GIS) and global positioning system (GPS) technologies, it has been a hot spot to monitor and study landscape pattern and change by integrating 3S technology. Meanwhile, many studies have been carried out and some results have been obtained based on 3S technology concerning dynamic changes of landscape pattern in the PRD. However, because application of landscape ecology in the PRD is in an early stage, not all issues have been systematically explored. In this paper, the application of 3S technology used in studying landscape pattern and change of the PRD is discussed, and then some expectations are also put forward, so as to provide some necessary references and support for monitoring and studying changes of landscape pattern in the PRD.
