Problems solved by technology
[0002] Collapsed hills are mainly caused by landslides and scouring caused by damage to the hillside soil under the dual influence of hydraulic force and gravity. Collapsed hills destroy basic farmland, lead to soil nutrient impoverishment, decrease in water and fertilizer retention capacity, deteriorate the ecological environment, and threaten public safety

Embodiment Construction
[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0019] figure 1 As shown, an embodiment of the present invention provides a method for judging the active degree of collapsed hillocks based on vegetation coverage, which mainly includes the following steps:
[0020] S1. Obtain the remote sensing image data of the collapsed hills in the southern red soil area: download the Gaofen-2 satellite remote sensing images of Hubei, Hunan, Jiangxi, Zhejiang, Anhui, Jiangsu, Guangdong, Guangxi and Fujian in 2018 from the national geographic monitoring cloud platform. One piece of data, ERDAS software was used to splicing and processing the above-mentioned multiple remote sensing images of the Gaofen-2 satellite to initially obtain the remote sensing images of the southern red soil area, and to preprocess the remo...

The present invention relates to the technical field of comprehensive control of water and soil conservation, in particular to a method for discriminating the active degree of collapsed hills based on vegetation coverage, which mainly includes the following steps: S1 acquiring remote sensing image data of collapsed hills in the southern red soil area, S2 calculating the vegetation coverage, S3 Grading classification, S4 statistical discrimination. Compared with the traditional method for discriminating the activity degree of collapsing hillocks based on the vegetation coverage, the method for discriminating the activeness of collapsing hillocks according to the present invention effectively avoids the tediousness and uncertainty of on-site manual investigation, and has the advantages of accurate discrimination results and wide application range Etc.
Description
technical field [0001] The invention relates to the technical field of comprehensive management of soil and water conservation, in particular to a method for judging the active degree of collapsed hillocks based on vegetation coverage. Background technique [0002] Collapse is mainly caused by the collapse and scouring of hillside soil under the dual influence of hydraulic and gravity. The occurrence of collapsing destroys basic farmland, resulting in depletion of soil nutrients, a decline in the ability to retain water and fertilizer, worsening the ecological environment, and at the same time threatening public safety. Therefore, it is of great significance to quickly judge the active degree of the collapsed gang, take targeted measures to prevent the collapse of the gang in advance, and reduce the security threat caused by the collapse of the gang. Vegetation is an important factor affecting the erosion of collapsing hills, so the vegetation situation in collapsing hills ...
