Method and device for measuring and calculating space quality evaluation of community consumption circle

Technical Field

The invention relates to the technical field of urban business space quality evaluation and urban and rural planning, in particular to a measuring and calculating method and device for space quality evaluation of a community consumption circle.

Background

Different from the 'Jumbo' type commercial complex which mainly takes retail, catering and entertainment in cities, the community business deeply influences the lives of residents due to the characteristics of convenience and high affinity. The community consumption circle is a commercial space range formed based on the consumption demands and behaviors of residents and is an important component of the community life circle. The community consumption area mainly considers the business state and the shop space of consumption provided in the community life circle, and the service radius of the community consumption area is consistent with that of the community life circle. And dividing the community consumption circle into three space ranges of five minutes, ten minutes and fifteen minutes of walking distance by referring to the division standard of the community life circle. The community consumption circle uses residents in the community range as service objects, and mainly uses the local business, so that the consumption demand of the residents is met, and the services required by the daily life of the residents are provided. How to improve the quality of the commercial space of the community, improve the system construction of the community consumption circle and optimize the layout and configuration of the community consumption circle is an important subject for guiding the construction of the residential life circle by the government and related planning departments.

As an important space composition of daily life of residents, the construction and development of community consumption circles are very important. The quality of the community consumption circle can be generalized to various contents such as space quality, shop quality, state abundance and the like. On one hand, the convenience and accessibility of space quality coverage need to adapt to the diversified travel modes of the residents at present; on the other hand, the importance of the state richness is highlighted in the case of an emergency public health event, so that the community consumption circle needs to meet the daily life needs of residents under various conditions in a state; in addition, after experiencing the new crown epidemic situation, residents have higher requirements on the quality of stores in the community consumption circle, and the environment is beautiful, the commodities are high in quality and low in price, and the sanitation and safety are guaranteed.

The construction of community consumption circles in China is mostly in the initial stage, the development is generally immature, and the functions are relatively incomplete. At present, domestic research results about commercial space mainly focus on the aspects of scale, space, layout and the like of commercial entities, and the research on community business and consumption circles is less; and the evaluation and feedback of the community business space by integrating the resident consumption behavior decision, the individual experience and the multi-source big data are insufficient. In addition, at present, no unified standard exists for evaluating the space quality of the community consumption circle, and quantitative research on the space quality of the community consumption circle on a micro scale is lacked.

In the post-epidemic era, the establishment of community consumption circles urgently needs a practical and effective feedback system to ensure the sustainable development of the community consumption circles. Therefore, a scientific and practical evaluation method needs to be established, so that the space quality of the current community consumption circle is evaluated and fed back, visual reference is provided for feeding back the condition of the current community consumption circle, the layout and configuration of the community consumption circle are optimized, and reference is provided for the thinking of building and developing the community consumption circle in China.
