Study on the Green Planning and Design of Livable and Employable Villages Based on Scale Hierarchical Distribution

The purpose of livable villages is to achieve three goals: the ecological nature of rural environment space, the livability of residential space, and the applicability of residential building space. The planning and design levels of village plots corresponding to these three objectives are different, and only considering a single level is prone to the problems of insufficient connectivity and low space utilization. In this regard, the green planning and design method of livable and suitable villages based on scale hierarchical distribution is studied. Based on Kropf’s combinatorial hierarchy theory, the hierarchical structure of “village texture-single texture-plot-building and site” is used to recognize and identify the spatial structure of villages from the whole block to the single building. Drawing upon the hierarchical distribution outlined above, the design is executed across five dimensions: ecological suitability, spatial concentration, spatial compactness, village planning expenditure, and village green environment. This multifaceted approach aims to fulfill hierarchical demands and achieve green, livable, and business-friendly village planning and design. Experimental results show that the connectivity of the proposed method is always higher than 88%, reaching 89.2% at the highest. The space utilization rate reaches 96.1% at the highest, which is practical.
