Problems solved by technology

[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.

Embodiment Construction

[0034] The preferred embodiments of the present invention will now be described in conjunction with the accompanying drawings.

[0035] The invention provides a kind of land quality evaluation method, it comprises the following steps:

[0036] S01. Obtain the attribute data of land samples from the land resource database; use the results of the second soil census in Guangdong Province as the main data source, and combine the socio-economic data such as the Guangdong Provincial Statistical Yearbook to establish a soil resource database; land evaluation attribute data support continuous missing, nominal, discrete, ordinal, numerical, character data, and other data types related to land evaluation; the attribute data of the land sample includes the following attribute categories: elevation, ground slope, soil Texture, soil pH, soil organic matter content, soil use type, topography, soil layer thickness, soil surface texture, organic matter content, profile configuration, slope as...

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.
