人工廊道效应与城市建成区景观演变的关系——以广州中心城区为例

The Relationship of Corridors Effect and the Constructed Region Landscape——A Case Study of the Central Area of Guangzhou

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。

Based on the data of the maps of the central area and GIS, choosing the area of the external circle highway in Guangzhou as a case study area, the paper studied the relationship between the corridors effect and the urban landscape in the central area. The conclusions were drawn as follows： （1）The conic relationship existed between the corridor and the urban landscape. （2） The combination of the corridor and the urban landscape was not changing synchronously, change but the extents were changing accordantly. （3）The corridors effect caused clearly the of the urban landscape, and then the urban landscape was often expanding directionally. The result could provide the reference for the extending urban landscape and the protection of the environment.
