Study on the Building Nodal Network Diagram of Rural Settlements'Plane Figure:From Effective Visible Space to First-Order Neighborhood
In rural settlements,buildings gather and grow in the spatial way and self-organizing mechanism,thus forming complex local parts of space in the settlements.Each building establishes order relation with other buildings through certain local space.By solving the quantity of order relation between all these pairs of buildings with spatial correlation between each other,the morphological order trend of the whole settlement can be gathered through statistics.In this process,the author has used the building node network diagram based on the principle of effective visible space to measure the order relationship between two buildings.On the basis of the analysis and evaluation,this paper uses the spatial central axis to divide the settlement space,forming household domains of buildings,and determines whether there is a significant spatial correlation between the two buildings according to the principle of the adjacency of the household domains and the restriction of the influence distance,and then draws the building nodal network diagram based on the principle of the first-order neighborhood.The improvement of the method from the effective visible space network diagram to the first-order neighborhood network diagram can focus the research object on the more core local space,and then make the network diagram more concise and data operation more efficient.
