规模与生态增长并举的城市开发边界划定——以东湖国家自主创新示范区为例

Urban Development Boundary Delimitation For Both Scale And Ecology Growth: East Lake Innovation Model District Case

文章通过规划区域内的总体规划规定的建设用地规模来确定城市增长阈值,综合水、地质、游憩与生物多样性4个关键性单一因子安全格局,构建综合生态安全格局;在此基础上,构建基于生态安全格局的城市增长模型,以此确定城市增长的空间形态,综合考虑空间形态与规模划定城市开发边界,为研究未来的城市扩展与开发建设提供了有力依据,使划定的边界既考虑了规划区发展的要求,又兼顾了生态属性。

The paper studies the urban growth limit based on the land use specified in the master plan of the district. It studies four critical elements： water, geology, recreation, and biodiversity, establishes ecological safety layout, urban growth model, spatial morphology, and urban development boundary. It sets a sound foundation for future urban expansion and development, and the boundary considers the demand of both development and ecology.
