Embodiment Construction

[0059] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0060] Based on the fact that existing methods for judging farmland construction areas mostly use subjective judgments, and use the methods of cultivated map spots and administrative regions to divide, resulting in the problem of emphasizing quantity over quality and high cost of high-standard farmland construction, this invention provides a method for judging farmland construction areas .

[0061] The method for judging the farmland construction area, such as figure 1 shown, which includes:

[0062] Step 110, determine the research area, and obtain the cultivated land quality data of the research area;

[0063] The research area generally selects the county range, and ...

Abstract

The invention relates to the field of farmland construction and land consolidation, in particular to a farmland construction area determining method. The method comprises steps of selecting a study area, and performing meshing, mesh unit encoding and data preprocessing on the study area; calculating judgment indexes of comprehensive quality of farmland in a mesh environment; performing normalization processing on the judgment indexes, and calculating and judging weights of the indexes relative to the comprehensive quality of the farmland; evaluating the comprehensive quality of the farmland with a multifactor comprehensive evaluation method, and dividing a high-standard farmland construction area with a natural discontinuity point grading method. Compared with the farmland construction area dividing method based on farmland map spots or administrative regions in the prior art, the farmland construction area determining method evaluates the farmland more scientifically and is more objective and obtains more accurate results through numerical evaluation based on the judgment indexes, high-standard farmland can be obtained through farmland construction, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the fields of farmland construction and land improvement, in particular to a method for judging farmland construction areas, which classifies farmland construction and provides reference for subsequent construction of high-marked farmland. Background technique [0002] Building high-standard farmland is an important way to realize the protection of cultivated land from quantity protection to quantity and quality protection. Building high-standard farmland is an important way to transform traditional agriculture and develop modern agriculture, which is conducive to exerting organizational effects and realizing large-scale operations. Through the construction of high-standard farmland, the concentration and scale of cultivated land can be realized, and the problem of sporadic segmentation of cultivated land can be broken. [0003] The construction of high-standard farmland should comprehensively consider various factors such as ...
