Description

Technical Field

[0001] The present invention relates to the field of built environment assessment of urban residential areas, and more specifically, it relates to a method and corresponding process for effectively assessing the human settlement environment of a target old residential area in the pre-stage of the old residential area renewal project with the joint participation of multiple parties. Background Art

[0002] With the progress of urbanization in my country, residential areas located in the core areas of cities, especially in the central areas of medium and large cities, are facing many obvious difficulties and challenges, such as the aging of buildings and facilities, the lack and abandonment of service facilities. At the same time, with the aging of the urban population and the high-density residence of the elderly in the central areas of cities, these old residential areas are unfriendly to the living conditions of the elderly, which has further promoted the renewal of urban central residential areas to become more aging-friendly.

[0003] At the same time, a large number of problems have gradually been exposed in the basic services and management of aging residential areas in the central city, which has further led to a decline in the quality of living environment in old urban residential areas. A series of derivative problems have emerged due to poor management, such as low efficiency of centralized decision-making, difficulty in promoting renewal, and untimely evaluation of renewal effects.

[0004] In addition, professional evaluations based on built environments such as residential environments show a positive trend towards specialization and domain-based evaluations, but there are practical shortcomings such as being out of touch with reality and low resident participation. Although surveys and research on residents' residential satisfaction are relatively abundant, they are still relatively professional, and the resulting root-stick strategies are not objective enough and the strategy steps are unclear. Summary of the invention

[0005] Based on the above background technology, and in order to solve the shortcomings and deficiencies of the above background technology to a certain extent, the purpose of the present invention is to promote the efficient and orderly advancement of the physical renewal of old urban residential areas. Before the implementation of the project, it is necessary to achieve the efficient participation of multiple parties and strive to plan and design the old residential area renewal project in a scientific and orderly manner, so as to achieve the design and formulation of specific residential area renewal implementation plans in a scientific and orderly manner while facilitating the effective participation of multiple parties.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions. A method for evaluating the quality of residential environment in old urban residential areas based on comprehensive consideration and parallel consideration of expert evaluation and resident evaluation, the specific steps of the method are as follows: S1-carry out preliminary investigation of residential environment quality; S2-conduct several rounds of expert evaluation; S3-conduct residents' residential satisfaction evaluation; S4-calculate evaluation scores, calculate weights of problem elements and rank them by importance; S5-zoning of "daily life residential clusters" in old residential areas; S6-determine the importance ranking of problem elements and determine the phased implementation plan for the renewal project.

[0008] As a further refinement of the present invention, the mathematical analysis model of "problem elements → residents' residential satisfaction" described in step three is specifically a one-way impact analysis model of existing problem elements in the living environment of old residential areas on residents' residential satisfaction, which is listed in layers and items.

[0009] As a further refinement of the present invention, the specific steps of conducting several rounds of expert evaluation described in step S2 are as follows: Step 1: Conduct the first round of expert evaluation based on the expert evaluation questionnaire obtained in step S1, and mobilize multiple experts to conduct simultaneous investigation and evaluation and scoring; Step 2: Adjust and improve the corresponding expert evaluation questionnaire according to the feedback from the first round of expert evaluation, and directly apply it to the second round of expert evaluation; Step 3: Conduct the second round of expert evaluation based on the expert evaluation questionnaire adjusted and improved in the first round, and mobilize multiple other experts to conduct simultaneous investigation and evaluation and scoring; Step 4: Adjust and improve the corresponding expert evaluation questionnaire according to the feedback from the second round of expert evaluation, and directly apply it to the third round of expert evaluation; Step 5: Repeat the steps similar to the first and second rounds of expert evaluation above, conduct no less than 3 rounds of expert evaluation, through repeated expert evaluation feedback and corresponding adjustment and improvement of the questionnaire, and directly apply it to the next round of expert evaluation, until the final round of expert evaluation (the specific evaluation round depends on the current status of the target residential area and the evaluation status); Step 6: Collect and summarize the results of previous expert evaluations and organize them into a data list for subsequent score calculation.

[0010] As a further refinement of the present invention, the specific steps of evaluating residents' housing satisfaction described in step S3 are as follows: step (1): based on the residents' housing satisfaction questionnaire obtained in step S1, conduct residents' housing satisfaction evaluation in period A; step (2): based on the residents' housing satisfaction evaluation results in period A, add the surveyed question elements and adjust the housing satisfaction analysis model, which is further reflected in the adjustment of the residents' housing satisfaction questionnaire; step (3): using the housing satisfaction questionnaire adjusted and improved based on the feedback results of the residents' housing satisfaction evaluation in period A to conduct residents' housing satisfaction survey and evaluation in period B; step (4): comprehensively summarize the evaluation results of residents' housing satisfaction evaluation in periods A and B, and summarize the evaluation scores for the calculation of question element weights and importance ranking in step S4; step (5): based on the summary of the results of social questions in the questionnaire and the summary of corresponding data, prepare for the "daily life residential cluster" zoning in step S5.

[0011] As a further refinement of the present invention, the specific steps of calculating the evaluation score, calculating the weight of the problem elements and ranking the importance in step S4 are as follows: Step ①: Calculate the evaluation score of old residential communities by problem element type based on the data obtained from the expert evaluation results; Step ②: Calculate the weight of the problem elements based on the data obtained from the residents' residential satisfaction evaluation results; Step ③: Calculate the importance ranking of the problem elements based on the data obtained from the residents' residential satisfaction evaluation results, in preparation for the subsequent step S6 problem element ranking calculation; Step ④: Comprehensively calculate the evaluation scores of old residential communities by problem element type and the corresponding weight index of the problem elements, and calculate the overall evaluation score of the target residential community, in preparation for the subsequent step S5 "daily life residential cluster" zoning design.

[0012] As a further refinement of the present invention, the specific steps of zoning the "daily life residential clusters" of the old residential areas described in step S5 are as follows: Step I: Based on the social survey data (objective physical data) obtained from the residents' residential satisfaction evaluation in step S3, a basic information plane map of the target original old residential community is prepared, and the overall scores of each residential community calculated in step S4 are marked accordingly; Step II: Preliminary merger of residential communities with similar basic information to form a preliminary residential cluster division; Step III: Calculate and simulate with reference to the residents' walking distance, and at the same time refer to relevant factors such as urban road network density and road width, adjust and improve the preliminary residential cluster division results, and obtain a preliminary zoning map of "daily life residential clusters"; Step IV: Finally, with reference to the overall evaluation scores of each residential community, further weighted calculation is carried out to obtain the comprehensive evaluation scores of each "daily life residential cluster", and marked on the zoning map to obtain a detailed zoning map of "daily life residential clusters", so as to prepare for the subsequent determination of the priority of the implementation of the "daily life residential cluster" update.

[0013] As a further refinement of the present invention, the specific steps of determining the importance ranking of problem factors and determining the phased implementation plan of the renewal business as described in step S6 are as follows: step i: preparing a problem factor importance ranking table based on step S4; step ii: dividing the problem factors into score segments according to the scores obtained, and obtaining a problem factor score segment ranking table; step iii: simultaneously referring to the detailed zoning map of the "daily life residential cluster" and combining the problem factor score segment ranking table and the problem factor improvement practical strategy considerations to conduct a preliminary formulation of the residential area renewal business plan, in preparation for the implementation of the subsequent old residential area living environment business plan.

DETAILED DESCRIPTION

[0016] The following will provide further description and explanation in conjunction with the accompanying drawings illustrating the present invention.

[0017] Instructions attached Figure 1 ,The implementation steps of the present invention can be divided into two major parts, namely the “assessment data collection and aggregation phase” (S1+S2+S3) and the “assessment data processing and application phase” (S4+S5+S6).

[0018] Among them, the "data collection and aggregation stage" can be divided into step S1 of the "data collection preparation stage" and steps S2 and S3 of the "data on-site collection and post-aggregation stage".

[0019] The “evaluation data processing and application phase” can be further divided into step S3 of the “data accounting processing phase” and steps S5 and S6 of the “data application phase”.

[0020] Instructions attached Figure 1 It can be clearly seen that steps S2 and S3 are carried out simultaneously, and there are common problem elements that are supplemented and learned from each other as the investigation and research proceed. Therefore, in the specific implementation process of S2 and S3, it is necessary to focus on making careful plans for the time and period of implementation so that they can achieve the core purpose of complementing each other and building on each other.

[0021] In addition, the attached instructions Figure 1 It can also be clarified that steps S5 and S6 are also carried out simultaneously, and are both based on the application of the obtained data, and respectively focus on the creation using the obtained data - step S5 and the plan and design based on the obtained data do not affect each other, and are respectively connected to different subsequent business processes outside the framework of the method of the present invention, and correspond to different subsequent implementation purposes.

[0022] Instructions attached Figure 2 , it can be clarified that the specific implementation process of step S1 of the present invention: the preliminary investigation stage of the residential environment quality includes "one basis", namely: summarizing the "common problem elements"; "two results", namely: the expert evaluation questionnaire and the residents' residential satisfaction questionnaire; and "two cycles", namely: the expert questionnaire adjustment and improvement cycle based on the questionnaire and questionnaire reliability testing and calculation and the residents' residential satisfaction questionnaire adjustment and improvement cycle.

[0023] The "common problem elements" of "one foundation" are the summary and refinement of similar elements for the common problems of the target residential community. They are the fundamental research elements for the implementation of the method of the present invention and need to be analyzed and summarized through rigorous preliminary research.

[0024] Among the "two results", the expert evaluation questionnaire is determined based on the Delphi method, while the residents' housing satisfaction questionnaire is designed and produced based on the summarized common problem elements and the constructed housing satisfaction mathematical analysis model. These two results will be respectively applied to the investigation and evaluation stages of steps S2 and S3 of the present invention.

[0025] The “two cycles” aim to repeatedly verify the two results obtained, and through multiple rounds of inspection and verification, ensure that the “two achievements” in the actual investigation stage are practical, efficient, scientific and rigorous, but still concise and clear.

[0026] Instructions attached Figure 3 , the specific implementation process of step S2 of the present invention: the expert evaluation stage can be determined, wherein the core concept is multiple rounds of expert evaluation with real-time feedback and real-time adjustment.

[0027] Specifically, each round of expert evaluation consists of four sub-steps: "evaluation → feedback → adjustment → application", which effectively connects each round of expert evaluation until the final round of expert evaluation is completed, and step S2 of the present invention is terminated.

[0028] It is worth noting that the expert evaluation results and data of each round in step S2 of the present invention are for reference only and will be transferred to the subsequent step S4 as basic data for calculation and processing.

[0029] Instructions attached Figure 4 , the specific implementation process of step S3 of the present invention: the residential satisfaction evaluation stage can be determined, wherein the core principle is to distinguish two specific periods for residential satisfaction investigation and evaluation.

[0030] Among them, after the residents' residential satisfaction evaluation in period A, it is necessary to add and supplement the elements of the survey questions, and it is necessary to refer to the results of each round of expert evaluation feedback in step S2, and then adjust the corresponding residential satisfaction analysis model, which is then reflected in the adjustment of the residential satisfaction questionnaire and further applied to the residents' residential satisfaction evaluation in period B.

[0031] After the residents' satisfaction evaluation in two specific periods, the evaluation results and data are directly transferred to step S4 for calculation and processing; on the other hand, the basic information elements of the target old residential community are summarized and further transferred to the zoning design of the "daily life residential cluster" in the old residential area in step S5.

[0032] Instructions attached Figure 5 , the specific implementation process of step S4 of the present invention: evaluation score calculation, problem element weight calculation and importance ranking stage can be determined.

[0033] Among them, the calculation of the overall evaluation score of the target residential community requires the evaluation scores of the old residential communities calculated by the problem element types from the expert evaluation stage and the problem element weights calculated from the data from the residential satisfaction evaluation stage, and then the overall evaluation scores of each target community are calculated scientifically and accurately, achieving the core goal of the present invention of comprehensively referring to experts and ordinary residents for evaluation and analysis, and can be further transferred to step S5 for the zoning of daily life residential clusters.

[0034] At the same time, based on the survey data obtained in the residents' housing satisfaction evaluation stage in step S3, the importance of problem factors is ranked based on the housing satisfaction analysis model, and it can be further transferred to step S6 to rank the problem factors and update the formulation of the business plan.

[0035] Instructions attached Figure 6 , it can be determined that the specific implementation process of step S5 of the present invention: the zoning stage of the “daily life residential cluster” in the old residential area, the core content of which is the drawing of the detailed zoning map of the “daily life residential cluster” of the target residential area.

[0036] Among them, the division of "daily life residential clusters" for the target residential area went through three stages, namely: the plane annotation stage of basic information, the preliminary zoning map of "daily life residential clusters" and the detailed zoning map of "daily life residential clusters".

[0037] In the process of drawing the preliminary zoning map of "daily life residential cluster", it is necessary to base it on the basic information map of the residential area, supplemented by the calculation of the residents' walking distance and the form of the relevant road network. Specifically, the residents' walking distance generally refers to the division principles of the concept of living circle in the new national standard "Urban Residential Area Planning and Design Specifications" GB0180-2018, namely: 15-minute living circle, 10-minute living circle, 5-minute living circle and residential group settings. The present invention integrates the residential area scope defined by the 5-minute living circle and the smaller residential group, determines the distribution requirements and density requirements of its basic social service facilities, and further compares the obtained problem elements to rank them, and can further complete the comparison and supplement of the corresponding problem elements.

[0038] The reference to the urban road network is mainly through the reference to the level, width and location of urban roads, eliminating the special impact of the difficulty, time and location of road travel on the daily walking distance of residents and the use of related facilities, so as to achieve the zoning of "daily life residential clusters" that can truly reflect the daily behavior range and habits of the residents within it, and on the basis of not affecting their living habits and behavioral characteristics, the subsequent renewal of old residential areas based on the new zoning of "daily life residential clusters" can be planned and designed.

[0039] Next, based on the reference of the overall evaluation score of the residential area obtained in step S4, the preliminary divided "daily life residential cluster" is fine-tuned and improved to complete the drawing of the detailed division map of the "daily life residential cluster".

[0040] It should be noted that the new concept of residential area zoning of "daily life residential clusters" proposed in the present invention attempts to carry out scientific, rigorous and appropriate re-planning of old residential areas in the central urban areas of medium and large cities. It mainly targets the abandoned status of such old residential areas, and attempts to redefine the basic residential area management boundaries through the zoning of "daily life residential clusters". This will also better adapt to the promotion of subsequent old residential area renewal projects.

[0041] In addition, in the process of demarcating "daily life residential clusters", only the walking distance of internal residents is considered because such old residential areas not only have obvious old buildings and environments, but also the proportion of elderly residents among their residents is showing a general trend of increasing year by year. Therefore, only the impact of walking distance is considered, while non-motor vehicles are more suitable for medium and long-distance transportation, which is a focus on the high proportion of elderly residents. In addition, regarding the impact of public transportation on the zoning of "daily life residential clusters", the zoning design of "daily life residential clusters" is carried out with reference to the location, density and traffic direction of fixed stations.

[0042] Instructions attached Figure 7, the specific implementation process of step S6 of the present invention: ranking of problem elements and formulation of updated business plan can be determined. Its core goal is to divide the ranking of the importance of problem elements from step S4 of the present invention into score segments based on specific score values, so that the subsequent update plan can be designed and planned according to several stages.

[0043] Among them, the residential area renewal business plan, which is the final result formulated in step S6 of the present invention, is designed and produced based on the problem element score segment ranking table, and at the same time refers to the zoning status of the "daily life residential cluster", as well as the difficulty of the practical operation of each problem element improvement, the implementation cycle, the previous and next correlations and other implementation elements, which can be further applied to the implementation and promotion of the subsequent residential environment renewal business in old residential areas. Specific implementation plans and promotion strategies.
