Abstract

Abstract: Urban Growth Boundary (UGB) is an effective tool to control urban sprawl,and protect ecological space.The study selected 11 factors such as population density,residents’ activity distribution and infrastructure layout,to quantify the expansion potential of residential activity space.Constructing ecological constraint based on vegetation coverage,and develop coordination rules.Combine both as CA model constraints to simulate urban construction,then delineate urban growth boundary.The results show that the delineation of urban growth boundary is consistent with the framework of urban spatial development in Changsha’s “13th Five-Year Plan”. Moreover, the delineated boundary avoids occupying important ecological resource and guides the city to expand in suitable area. Generally, the goal to balance the urban development and ecological protection is achieved.

Key words: urban growth boundary, residential activity space, ecological constraint, CA model, Changsha
