Embodiment 1

[0055] like figure 1 As shown, a land value assessment method based on multi-source data includes the following steps:

[0056] S110. Obtain the data of multiple impact index sets of the land to be evaluated, and the multiple impact index sets respectively include multiple impact factors;

[0057] S120, determine the score of the impact indicator set where the multiple impact factors are located according to the multiple impact factors;

[0058] S130. Use the AHP to assign weights to the scores of the impact index set to calculate the value index to obtain the land value index, and map the land value index to a value regression model to obtain the land value of the land to be evaluated.

[0059] In Example 1, the data of multiple impact index sets of the land to be evaluated are obtained, the multiple impact index sets include but not limited to productivity index set, suitability index set and risk index set, each index set includes Multiple impact factors, from the impact ...

Embodiment 2

[0061] like figure 2 As shown, a land value assessment method based on multi-source data, including:

[0062] S210. Obtain the data of multiple impact index sets of the land to be evaluated, and the multiple impact index sets respectively include multiple impact factors;

[0063] S220. Sorting the influence levels of the plurality of influence factors according to the degree of influence of the plurality of influence factors on the influence indicator set in which the plurality of influence factors are located;

[0064] S230. Determine the impact values ​​of the plurality of impact factors step by step according to the impact level ranking, and construct a judgment matrix according to the impact values;

[0065] S240. Calculate the eigenvector of the judgment matrix to obtain the weight value of the single ranking of the plurality of influencing factors;

[0066] S250. Obtain the standard values ​​of the multiple impact factors, and multiply and compound the weight values ​...

Embodiment 3

[0121] like image 3 As shown, a land value assessment method based on multi-source data, including:

[0122] S310. Obtain data of multiple impact index sets of the land to be evaluated, where the multiple impact index sets respectively include multiple impact factors;

[0123] S320. Determine the score of the impact index set where the multiple impact factors are located according to the multiple impact factors;

[0124] S330, constructing a value index calculation formula and a value regression model;

[0125] S340. Perform value index calculation on the score of the impact index set according to the value index calculation formula to obtain a land value index;

[0126] S350. Map the land value index to the value regression model to obtain the land value of the land to be evaluated.

[0127] In embodiment 3, the land value index is jointly calculated by productivity score, suitability score and risk score. Use the AHP method to evaluate the weights of the three, and calc...

Abstract

The invention discloses a land value evaluation method based on multi-source data. The method comprises the following steps: acquiring data of a plurality of influence index sets of to-be-evaluated land, wherein the plurality of influence index sets respectively comprise a plurality of influence factors; determining scores of the influence index sets where the plurality of influence factors are located according to the plurality of influence factors; and assigning weights to the scores of the influence index sets by using an analytic hierarchy process, carrying out value index calculation to obtain a land value index, and mapping the land value index to a value regression model to obtain a land value of the to-be-evaluated land. According to the invention, the multi-source data influencing land value evaluation from all aspects is comprehensively obtained, influences of the multi-source data on the land value evaluation are quantified, land value index modeling is carried out, and the land value index is mapped to an actual value, so that value evaluation can be carried out on the same type of land subsequently, errors possibly caused by manual investigation are eliminated, and repayment capabilities of farmers can be evaluated more objectively.

Description

technical field [0001] The present invention relates to the field of big data processing, in particular to a land value evaluation method and device based on multi-source data. Background technique [0002] Land is a natural-economic-social complex, and its value includes natural attributes and long-term human labor development results. At present, China's urban state-owned land market is relatively complete, and an evaluation system for the quality and value of urban state-owned land suitable for China's national conditions has been established, but there is no standard system for the evaluation of agricultural land. Since the proposal of "vigorously carry out the work of grading and certifying rural land rights, and improve the registration system of rural land contractual management rights nationwide", improving the implementation of collective ownership, stabilizing farmers' contracting rights, and releasing land management rights have all been planned. Promote the deve...
