S102, obtaining geographic information data of each evaluation index in a plurality of preset evaluation indexes, and determining an influence factor model of each evaluation index according to the geographic information data;

in the embodiment of the application, when generating the evaluation index, firstly, according to the development rule and the cityThe related parameters of the market law are used for determining an evaluation index, then an evaluation index system is established through different conditions of different cities, and the weight W affecting the evaluation index of the city is determined _i . A set of evaluation index library is built, mainly comprising two layers, 16 specific indexes of each aspect 6 and 2 cost indexes, for example, as shown in table 1.

In the embodiment of the application, when the influence factor model of each evaluation index is determined according to the geographic information data, the geographic information data can be imported into a graph and a geographic information processing platform, and the influence factor model of a single evaluation index is built according to the influence parameters of each evaluation index on the land value, so that the influence factor model of each evaluation index is obtained.

In general, the influence factor model of each evaluation index includes, but is not limited to, "model for present situation", "model for terrain data", "model for influence of neighboring facilities", "model for influence of urban public facilities", "model for development intensity", and the like.

2. consistency check of judgment matrix

During the evaluation, the evaluator cannot accurately judge the values of all the factors, and according to the existence of errors, the characteristic values of the judgment matrix are deviated. In constructing the judgment matrix, judgment is not required to have complete consistency, but judgment is required to have substantial consistency, otherwise analysis cannot be performed. Therefore, the maximum characteristic root lambda is obtained _max After that, consistency checks are also performed.

A. Computing a consistency index CI

；

When lambda is _max Slightly larger thann, the rest characteristic roots are close to zero, the judgment matrix has satisfactory consistency, and the weight vector W obtained by applying the characteristic root method can accord with the reality. In general, the larger the judgment matrix order n is, the larger the CI value is. In order to measure the consistency of the judgment matrixes of different orders, the average random consistency index RI value of the judgment matrixes is introduced. For the 1-9 order matrix, RI values are shown in the table.

RI table:

B. calculation of random consistency ratio CR

CR=CI/RI

If the random consistency ratio CR is calculated to be less than 0.1, the judgment matrix is considered to have satisfactory consistency, otherwise, the judgment matrix needs to be readjusted until the consistency is met.
