Plastic film mulching farmland remote sensing monitoring method based on texture features

Abstract

The invention discloses a plastic film mulching farmland remote sensing monitoring method based on texture features, and the method comprises the steps: S1, carrying out preprocessing of remote sensing image data; S2, building a plastic film mulching agricultural remote sensing monitoring classification system; S3, collecting irregular polygon samples of different ground features in the classification system through visual interpretation, and drawing the outline of a regular polygon sample of an element at a preset size through visual interpretation; S4, extracting a plurality of types of texture features based on the multiband data of a remote sensing image through employing a gray co-occurrence matrix method, and extracting the texture features; S5, carrying out dimension reduction of the extracted texture feature parameters S6, constructing input features in four directions based on the selected texture features serving as a classification feature parameter set; S6, constructing the input features in four directions; S7, carrying out the classification of ground features of the classification system through employing a classifier. The invention proposes a new method for monitoring a plastic film mulching farmland.

Description

Technical field [0001] The present invention relates to remote sensing monitoring technology, and more specifically, to a remote sensing monitoring method for mulching farmland based on texture characteristics. Background technique [0002] Plastic film mulching cultivation can significantly improve farmland temperature, light, water, air, fertilizer and other habitat conditions, increase soil moisture, promote crop growth, shorten the growth period, avoid later disease and insect pests and natural disasters such as dryness, heat, and wind, and greatly increase crop yields It is one of the key cultivation techniques in arid and semi-arid areas, low temperature and water shortage areas, temperature and precipitation changes, and areas with large regional differences. [0003] However, after the crops are harvested, the mulch film remaining in the farmland will cause the following adverse effects: environmental pollution (white pollution in the field); soil permeability, water and nu...

AI Technical Summary

Problems solved by technology

However, the current spatial distribution pattern, distribution area and change characteristics of plastic film mulched farmland in my country are still unclear.

Therefore, it is impossible to provide a basis for the scientific planning and management of plastic film production, use, and residual film recycling, nor can it provide a reference for mitigating the negative impact of plastic film covering technology and finding effective ways to solve problems.

It is also unable to provide basic data for other research (crop phenology changes, surface temperature and humidity, evapotranspiration, etc.)
