the index V comprises a first-order index: multiple containment and urban features, wherein the multiple containment includes the following secondary indicators: road barrier-free facility setting rate, resident population housing guarantee service coverage rate, population number ratio residing in shed areas and villages in cities, and city characteristics comprise the following secondary indexes: city history culture and city psychology civilization construction conditions.
4. The sustainable urban physical examination method of claim 1, wherein the physical examination is divided into four levels according to the organizational hierarchy of the city: the method comprises the steps of sequentially decomposing physical examination indexes from top to bottom of four levels of a city, an urban area, a street and a community, firstly performing basic examination from the level of the city, then performing special examination on different levels of the city, performing special examination according to the characteristics of the city with special index definition, and performing data summarization from bottom to top after data acquisition and input of physical examination indexes are completed on each level, so that overall physical examination data of the city are obtained.
5. A sustainable urban physical examination method according to claim 1 or 4, wherein said physical examination works in the form of urban physical examination, third party physical examination and social satisfaction survey,
the main body of the urban self-examination work is the urban government;
the third-party physical examination is to rely on professional institutions to carry out urban physical examination;
the social satisfaction survey is subjective judgment and evaluation of urban residents on urban objective physical examination indexes, and comprises questionnaire survey and on-site visit modes, wherein satisfaction degree of the residents on urban construction development is investigated and analyzed, and prominent problems and short plates felt by the residents are found.
6. The method of claim 5, wherein the physical examination is performed by setting a to ij And if the importance comparison result of the index i and the index j is that the comparison matrix has the following properties:
comparing matrix index a ij The scale method of (2) is as follows:
7. the sustainable urban physical examination method according to claim 6, wherein the maximum eigenvalue and the corresponding eigenvector are calculated for each pair of comparison matrices and consistency check is performed as follows;
determining the influence degree of each index of the lower level on the index of the upper level, and carrying out consistency test, wherein the influence degree is the weight value of the index, W is set as the weight value, and if the comparison matrix A is a consistency matrix, the corresponding normalized feature vector of the maximum feature root n is shown in a formula (2):
wherein w is i A weight value indicating the degree of influence of the lower i-th index on the upper index;
if the comparison matrix A is not a uniform matrix, taking the normalized eigenvector corresponding to the maximum eigenvalue lambda as the weight vector, W is as shown in formula (3):
Aw＝λw，w＝{w 1 ,w 2 ,…w n }(3)
due to lambda being continuously dependent on a ij The larger the lambda is than n, the more serious the inconsistency of the comparison matrix A is, the larger the inconsistency is, the larger the judgment error is caused, and therefore the inconsistency of A can be measured by the value of lambda-n;
defining a consistency index CI:
ci=0, with complete consistency; CI is close to 0, and satisfactory consistency is achieved; the larger the CI, the more serious the inconsistency; to measure the size of CI, a random uniformity index RI is introduced:
the random consistency index RI is related to the order of the comparison matrix; when checking whether the comparison matrix has satisfactory consistency, the CI and the random consistency index RI are also required to be compared to obtain a check coefficient, and the formula is shown as (6):
if CR <0.1, the comparison matrix is considered to pass the consistency check.
8. A sustainable urban physical examination system is characterized by comprising a definition index module, a physical examination diagnosis module, a physical examination evaluation module and a lifting scheme module,
the system achieves urban physical examination by the sustainable urban physical examination method of any one of claims 1 to 7.
9. A sustainable urban physical examination device, comprising: at least one memory and at least one processor;
the at least one memory for storing a machine readable program;
said at least one processor for invoking said machine readable program to perform the method of any of claims 1 to 7.
10. A computer readable medium having stored thereon computer instructions which, when executed by a processor, cause the processor to perform the method of any of claims 1 to 7.
