Embodiment Construction

[0056] Such as figure 1 As shown, a winter wheat-summer corn planting pattern remote sensing recognition method is characterized in that it specifically includes the following processes:

[0057] Step 1), obtaining data;

[0058] Step 2), initial processing of numbers;

[0059] Step 3), setting up a decision tree;

[0060] Step 4), run the decision tree, and make the winter wheat-summer corn planting pattern thematic map.

[0061] The method of obtaining data in step 1) is specifically as follows:

[0062] Download the 2015 Earth Observation Satellite Series Moderate Resolution Imaging Spectroradiometer MODIS 8-day synthetic spatial resolution at 250m ago from the NASA data sharing site ftp: / / ladsweb.nascom.nasa.gov / allData / 5 / MOD09Q1 / 2015 / Two-band apparent reflectance files, including 12 groups of key growth period data from Confucian calendar 289, 297, 321, 329 in the previous year to Confucian calendar 97, 105, 129, 137, 169, 177, 209 and 217 in the current year.

Abstract

The invention discloses a winter wheat-summer corn plantation mode remote sensing recognition method. The method concretely comprises the following processes of 1) obtaining data; 2) processing the data; 3) establishing a decision tree; 4) operating the decision tree, and producing winter wheat-summer corn plantation mode thematic graphs. The method uses less data, uses the maximum synthesis method of two sets of data and the simple logical comparison of the size, and establishes the decision tree. The method uses eight-day synthesis data, conducts the maximum synthesis using former and later eight-day synthesis data, and carries out cloud elimination, so that the extraction precision is high. The method is made according to farming system characteristics of the winter wheat-summer corn plantation zone, and has high extraction precision.

Description

technical field [0001] The invention relates to the technical field of remote sensing identification methods for ground objects, in particular to a remote sensing identification method for winter wheat-summer corn planting patterns. Background technique [0002] Agricultural production is different from industrial production. In the narrow sense of agricultural production, the objects of production are plants, which are affected by five natural environmental factors such as water, light, air, heat, and soil. Different plants require different natural conditions for growth and development, so there are obvious regional differences in spatial distribution. Different regions produce different structural varieties and quantities. For a long time, farmers have formed a relatively fixed production mode based on natural conditions and market demand, such as monocropping, intercropping, intercropping, etc. In the 20th century in China, agricultural farming was mainly manual.
