以广州环城高速包括的区域作为研究对象,基于1966、1979、1988、1999、2002、2005年中心城区地图数据和GIS技术,研究人工廊道效应与城市建成区景观演变的关系。结果表明:①人工廊道与建成区景观在数量上呈二次曲线关系;②人工廊道与建成区景观的变化具有非同步性和一致性;③人工廊道效应明显影响着建成区景观的梯度分异,且常常呈定向扩展。
Taking the area covered by the Guangzhou Ring Expressway as the research object, this paper studies the relationship between the artificial corridor effect and the landscape evolution of the built-up area based on the map data of the downtown area in 1966, 1979, 1988, 1999, 2002 and 2005 and the GIS technology. The results show that: (1) the landscape of artificial corridor and built-up area is quadratic curve in quantity; (2) the variation of artificial corridor and built-up area landscape is asynchronous and consistent; (3) artificial corridor effect obviously affects the landscape of built-up area Gradient differentiation, and often directional expansion.
