Problems solved by technology

The traditional evaluation methods of cultivated land quality generally focus on factors affecting crop development, such as soil quality and nutrients, and less consideration is given to factors such as transportation and cultivated land distribution that affect agricultural production, and cannot fully reflect the objective factors affecting cultivated land quality.
In addition, since the evaluation is multi-dimensional, there is no unified standard to give multi-dimensional comprehensive evaluation results, so it is difficult to make an intuitive comparison of the quality of cultivated land in different regions with a unified standard

Embodiment 1

[0072] refer to figure 1 , a regional cultivated land quality evaluation method, including the following steps:

[0073] Step S1: Obtain and number the cultivated land distribution map of a certain area;

[0074] Step S2: Obtain the cultivated land area;

[0075] Step S3: Calculate the evaluation grade of cultivated land soil fertility in the area;

[0076] Step S4: Calculate the dispersion of cultivated land distribution in the area;

[0077] Step S5: Calculating the index of favorable degree of planting in this area;

[0078] Step S6: Calculating score matrices of different dimensions;

[0079] Specifically, calculate the matrix of soil fertility score, average area score, distribution dispersion score, and planting favorable score;

[0080] Step S7: Calculate the total cultivated land quality evaluation index.

Embodiment 2

[0082] On the basis of embodiment one, a method for evaluating the quality of regional cultivated land comprises the following steps:

[0083] Step S10, obtaining the cultivated land distribution map of a certain area is obtained through satellite remote sensing image contour extraction or directly obtained from the local surveying and mapping department, and the cultivated land in the area is numbered according to its natural blocks, and the total number of blocks is N;

[0084] Step S20, obtain the area S of each piece of cultivated land in the region by means of on-site measurement or computer-aided calculation in combination with the cultivated land distribution map i (i=1,…,N), the total area of ​​cultivated land in the region and the average area of ​​arable land

[0085] Step S30, obtain the soil fertility of all cultivated land in the area, and give the soil fertility evaluation grade σ of each cultivated land i (i=1,...,N), calculate the total cultivated land soi...

Abstract

The invention discloses a regional cultivated land quality evaluation method and system, and belongs to the field of agricultural engineering. The method comprises the following steps: S1, obtaining and numbering a cultivated land distribution diagram of a certain region; S2, acquiring the cultivated land area; S3, calculating the cultivated land soil fertility evaluation grade in the area; S4, calculating cultivated land distribution dispersion in the area; S5, calculating a planting favorable degree index of the area; S6, calculating score matrixes of different dimensions; and S7, calculating a total cultivated land quality evaluation index. The quality of cultivated land in different areas can be visually compared according to a unified standard; and by standardizing the calculation process and defining the processing method, the cultivated land quality acquisition data is normalized and standardized, scientific researchers can quickly program and process cultivated land evaluation data, and the obtained result is repeatable and verifiable.

Description

technical field [0001] The invention relates to the technical field of agricultural engineering, in particular to a method and system for evaluating regional cultivated land quality. Background technique [0002] Cultivated land is a precious and limited resource in our country, and it is an important guarantee for the stable development of the country and the survival of the people. In agricultural engineering, the evaluation of cultivated land quality in a region is an important aspect that reflects the level and quality of agricultural development in the region. Cultivated land quality evaluation is an important task. Its quality level is related to many aspects such as food security, crop yield, agricultural development level, and ecological security. Cultivated land quality evaluation is an important part of the agricultural production process. It is of great significance to guide the agricultural sector to grasp the current situation of arable land, improve the qualit...
