阐述应用多源遥感数据及多目标空间分析手段,研究珠江三角洲地区土地利用变化驱动的非点源污染与该区水质环境演变的方法.充分利用不同遥感数据特点,有效融合高、低空间分辨率数据,将进一步提高土地利用变化动态遥感监测能力.充分利用珠江三角洲地区近年来土地利用土地覆盖研究成果,将有助于分析非点源污染驱动因子与珠江河口及邻近水域水质环境的恶化趋势.%This paper summarizes that Pearl River Delta Region has experienced rapid economic growth in the last over 20 years. Along with the economic development, great changes on land use status have taken place. However, the development in Pearl River Delta Region is closely linked with human activities, which has given rise to the increasing pollution problems and the serious pressure on water quality. And the fast urban expansion in Pearl River Delta Region can inevitably further worsen the water quality in Pearl River estuary and its adjacent waters. Therefore,it is significant to study the land use change in Pearl River Delta Region and its environmental effects on water quality.
