Optimization of urban opening space pattern based on landscape ecology

City is a spatial synthesis which consists of various buildings and urban opening space. With the developing of the urbanization, the urban planning will directly influence the sustainable development of a city, and the optimization of the urban zone pattern is the main section of the urban planning. The urban opening space is the main part of the urban landscape with important econ-function. Due to its flexibility, the urban opening space is becoming the object of the urban landscape pattern. In this study, some ecological problems during urban development were discussed, and a series of strategies of urban opening space pattern optimization have been put forward based on landscape planning theories.
