Since the end of 1800s ecology has been used in study on urban spatial structure. Within recent 20 years, the primary principles of landscape ecology have been frequently adopted in research on layout of natural open spaces in cities. This paper discussed definition and establishment of ecological landscape; with a case of Nanjing in China, analyzed the sustainabil ity of city form, explored the method of coordination of the natural and semi-natural landscape with the artificial building blocks in highly developed cities,and presented a pattern by which the ecological landscape was integrated with the city form. Its major content could be described as: integration of green wedges with star city form at the metropolis scale, integration of green way networks with road networks at the main city scale and integration of green corridors with neighborhoods at the street block scale. The case study may provide suggestions for ecological landscape restoration and for ecological security pattern establishment in urban areas.
