Based on TM images,ArcGIS and landscape ecology,4 typical roads in the Pearl River Delta are taken for example to analyze infl uence range of highway,and study the laws of highway construction infl uencing landscape patterns by reviewing landscape pattern changes in areas along the highways. According to the research,for Yuebei Section(north Guangdong) of Beijing–Zhuhai Highway,road construction has signifi cant infl uence on landscape patterns of the 300-m wide buffer zone(especially woodland and urban land); for Foshan–Kaiping Highway,road construction has significant influence on landscape patterns of the 1,000-m wide buffer zone(especially woodland and agricultural land); for Dongguan–Shenzhen Highway,road construction has signifi cant infl uence on landscape patterns of the 8,000-m wide buffer zone(especially woodland and urban land).
