Embodiment 1

[0054] see figure 1 , the soil suitability evaluation method that the present embodiment proposes specifically comprises the following steps:

[0055] Step S101: The first step is to select any soil evaluation method from fuzzy mathematics method, gray relational analysis method and comprehensive index evaluation method to obtain the first soil evaluation method. Select any soil evaluation method from the method and the comprehensive index evaluation method to obtain the second soil evaluation method, that is, select two evaluation methods from the soil suitability evaluation method. What needs to be explained here is that the selection of two The evaluation method includes two repeated evaluation methods, for example, fuzzy mathematics method-fuzzy mathematics method and the like.

[0056] Afterwards, according to the selected first soil evaluation method, the soil fertility parameters of the soil to be evaluated are calculated respectively.

[0057] Step S102: Calculate va...

Embodiment 2

[0090] Based on the soil nutrient factors measured in 8 sample plots in Henan County, Qinghai Province, an evaluation model was used to evaluate the soil fertility status in the study area, and it was used as one of the suitability evaluation index elements; combined with the 8 sample plots measured soil physical properties and other Soil suitability evaluation elements, again using a model to analyze the soil suitability status of 8 sample plots. Finally, the comparative analysis of the soil suitability evaluation results of different combinations was carried out. The evaluation of soil suitability involves two processes of fertility evaluation and suitability evaluation. One evaluation model can be selected for each process, and the following six combined evaluation models (Table 2) are selected to evaluate the soil suitability of the alpine grassland in Henan County, Qinghai Province. Of course, a single model will be used to compare the evaluation results.

Embodiment 3

[0099] see figure 2 , image 3 with Figure 4 , the present embodiment provides a soil suitability evaluation device comprising: sequentially connected selection module 1, calculation module 2 and search module 3, when in use, selection module 1 is used for the first step, from fuzzy mathematics, gray relational analysis and Select any soil evaluation method from the comprehensive index evaluation method to obtain the first soil evaluation method. In the second step, select any soil evaluation method from the fuzzy mathematics method, gray correlation analysis method and comprehensive index evaluation method to obtain the second soil evaluation method. Two soil evaluation methods, the calculation module 2 is used to calculate the various soil fertility parameters of the soil to be evaluated according to the selected first soil evaluation method, and use the obtained soil fertility parameters as suitability evaluation elements to use the second soil evaluation method Methods...

Abstract

The invention provides a soil suitability evaluation method and device and belongs to the soil assessment technical field. The soil suitability evaluation method comprises the following steps that: any one method is selected from a fuzzy mathematic method, a gray relational analysis method and an comprehensive index evaluation method as a first soil evaluation method; 2, any one method is selectedfrom the fuzzy mathematic method, the gray relational analysis method and the comprehensive index evaluation method as a second soil evaluation method; the soil fertility parameters of soil to be evaluated are calculated according to the selected first soil evaluation method, and with the obtained soil fertility parameters adopted as suitability evaluation factors, the second soil evaluation method is adopted to perform soil suitability evaluation to obtain a soil suitability coefficient; and a soil suitability evaluation level corresponding to the soil suitability coefficient is searched. With the above process adopted, the suitability evaluation of the quality of the soil is realized. The method and device are objective and scientific.

Description

technical field [0001] The invention relates to the technical field of soil evaluation, in particular to a soil suitability evaluation method and device. Background technique [0002] The soil suitability level can comprehensively reflect the soil quality and its suitability for planting crops, and to a certain extent reflect the interference of human production activities on the soil. The determination of the soil suitability level should comprehensively consider the physical, chemical and environmental conditions of the soil, which can assist farmers and managers to clearly consider the regional soil quality status. The purpose of soil suitability evaluation is to determine the suitability and limitations of different agricultural and animal husbandry production, to provide a scientific basis for determining the most suitable land use model, fully displaying the production potential of the soil, and preventing excessive soil reclamation. [0003] The traditional soil suit...
