Abstract: The method includes the following steps: first establishing urban street and urban plot elements, delineating publicly used parts of public and private property areas as streets, and delineating boundaries of privately owned land as plots; after defining urban streets and urban plots, obtaining accessibility levels of the street elements through depth, connectivity, and low connection rate, where the accessibility level of an urban plot includes an external value and an internal value, the external value is obtained through the levels of urban streets connected to the plot, and the internal value is obtained through the delineation of interlocking structure, basic structure, cul-de-sac structure, and embedding structure types of the urban plot and the urban streets; and based on calculation results of the accessibility levels of the urban streets and urban plots, making judgments from four aspects: upper level planning, commercial system, community system, and historic resources.

Abstract: The present invention discloses a method, system, storage medium and device for evaluating adaptive reuse of existing residential buildings. The method includes: substituting the research data of a to-be-evaluated residential building into an adaptability evaluation system to obtain an evaluation result, and determining a reuse mode of the to-be-evaluated residential building at a region position of a reuse mode decision-making matrix according to the evaluation result; the research data includes current quality data and reuse value data; each region of the reuse mode decision-making matrix corresponds to one reuse mode for existing residential buildings. According to the present invention, adaptability index data of the existing residential buildings are extracted through sample analysis based on a mathematical model, so that the evaluation value of the adaptability is obtained, and the most suitable reuse mode is determined by means of the reuse mode matrix.
