Abstract: Under the background of rapid urbanization, the intrinsic links between the scenic spot and its city are getting increasingly closer, so the design of the boundary between them has become more and more important. The boundary delimitation is guided by the resource value and accomplished in macro-scale; the land use at the boundary and relationship between the city and the spot should be studied in meso-scale; the design of Urban National Park boundary is considered in micro-scale. According to the Fractal Theory and Hierarchy Theory, the article discusses the boundary in three scales: macro, meso and micro. Focusing on the major characteristic and relationship of different scales, the essay forms a targeted strategy and realizes the scale transition. The adjustment of the land-use type in macro-scale forms a good interactive mechanism of the nature and city; the meso-scale optimizes the spatial order and improves the landscape experience; the micro-scale put forward four types of boundary space and corresponding design strategies.

摘要： 在快速城市化背景下，风景名胜区与所属城市联系日益紧密，“城-景”边界的处理重要性逐渐凸显。边界划定以资源价值为导向，一般在宏观尺度完成；边界处用地类型及城-景空间关系的疏理一般在中观尺度完成；而边界形式在微观层面探讨。通过分形理论、层次理论从宏观、中观、微观三个尺度对城-景边界进行研究，重点关注三个尺度的主要特征以及相互之间的衔接关系，实现尺度转化，进而形成具有针对性的设计策略。宏观尺度对用地类型进行调整实现风景与城市良性互动，中观尺度优化空间秩序、提升景观体验，微观尺度对边界空间进行分类，并提出相应的设计策略。
