| Abstract: | There are two essential types of landscapes in a city. The first type is buildings and traffic lands. and the second is greenlands, waters and related facilities. The ratio of these two types is a very important index to mirror the environment quality of a city. In the last 20 years, the urban area of Guangzhou has been expanding rapidly as the buildings and road systems increasing. However, the building density has been getting higher and higher, and the traffic getting more and more crowded.The agriculture land, waters and other greenlands have reduced speedily. Those have resulted in the degradation of urban landscape ecology in Guangzhou. Consequently, the quality of urban ecological environment and the environmental capacity of pollution in Guangzhou have been decreasing. That is the main barrier to the sustainable development of the city. Some measures to coordinate urban construction with ecological environment are suggested: improve the urban spacial structure, enhance afforestation of the city, and increase the area of waters. |
