Soil quality evaluation method and system

Abstract

The invention relates to a soil quality evaluation method, comprising the following steps: A, obtaining the attribute data of a soil sample from a soil resource database; B, excavating the attribute data of the soil sample to generate a plurality of relative rules; and C, inputting the attribute data of the soil sample to be evaluated, calculating the matching degree of the attribute data with each relative rule, finding out the most matching relative rule and evaluating the soil sample as a soil grade which corresponds to the most matching relative rule. The invention also provides an evaluation system of the soil quality and enhances the interpretability expressed by soil evaluation knowledge and the soil evaluation effectiveness.

Description

technical field [0001] The invention relates to the technical field of data mining and fuzzy matching, in particular to a land quality evaluation method and system. Background technique [0002] Land quality evaluation refers to the evaluation of the suitability, limiting factors and utilization potential of land for a specific purpose through the comprehensive identification of the natural attributes and socio-economic factors of the land, that is, the evaluation of the value of the land for the development of agriculture, forestry, animal husbandry and fishery , it is different from the comprehensive evaluation of land economy; there are many factors affecting land quality evaluation. In the process of land evaluation, different regions have different influencing factors, and each influencing factor has different effects on different production targets. Human subjective factors are also mixed in the quality evaluation, which affects the accuracy of land evaluation. Althou...

[0002] Land quality evaluation refers to the evaluation of the suitability, limiting factors and utilization potential of land for a specific purpose through the comprehensive identification of the natural attributes and socio-economic factors of the land, that is, the evaluation of the value of the land for the development of agriculture, forestry, animal husbandry and fishery , it is different from the comprehensive evaluation of land economy; there are many factors affecting land quality evaluation. In the process of land evaluation, different regions have different influencing factors, and each influencing factor has different effects on different production targets. Human subjective factors are also mixed in the quality evaluation, which affects the accuracy of land evaluation

Although new methods have been applied to land evaluation, and the accuracy of land evaluation has been improved to a certain extent, the interpretability of the obtained land evaluation knowledge expression is poor, and there are still many problems in practical application.
