【摘要】 聚落的边界由建筑部分的实边界与建筑之间空隙部分的虚边界连接而成。文章基于建筑外部空间理论与凸包原理，提出了一种求取聚落边界的新方法。首先利用Delaunay三角网求取聚落建筑之间的影响距离，继而绘制建筑节点网络图，以此求取聚落内两两之间具有直接可视空间关联的建筑之间的凸包，并叠加得出该聚落的公共空间，其外轮廓即为聚落的虚边界。综合实、虚两部分边界，得到完整的聚落边界图形。文章提出的新方法充分考虑了聚落内部建筑的疏密程度对聚落边界设定的影响，其结果更符合真实的空间感受，也更具科学性与合理性。更多还原

【Abstract】 The boundary of the settlement is formed by connecting the real boundary of the building part with the virtual boundary of the void part between the building. Based on the theory of building external space and convex hull, a new method of settlement boundary is proposed in this paper. Firstly, the influence distance between the buildings in the settlement was obtained by using the Delaunay triangulation network, and then the construction node network diagram was drawn. In this way, the convex hull between the buildings in the settlement with direct visual spatial correlation was obtained by superposition, and the public space of the settlement was obtained, whose outer contour was the virtual boundary of the settlement. By synthesizing the real and imaginary boundary, a complete settlement boundary graph is obtained. The new method proposed in this paper fully considers the influence of the density of the inner buildings on the settlement boundary setting, and the result is more in line with the real space feeling, and also more scientific and rational.更多还原
