Slope ecological restoration monitoring method

Abstract

A slope ecological restoration monitoring method comprises the following steps: S1, slope image data acquisition: acquiring two-dimensional time sequence visible light image data of a slope through an image device; S2, preprocessing the image, primarily screening the image data, and classifying according to the purposes of slope full view overall analysis, slope vegetation detail analysis and slope three-dimensional model reconstruction; and S3, vegetation image data analysis: extracting vegetation horizontal structure parameters through vegetation index inversion of two-dimensional image data, and extracting vegetation vertical structure parameters by reconstructing the three-dimensional model of the two-dimensional image. According to the method, specific and real vegetation evaluation index values can be obtained by using image data, and long-term tracking monitoring is performed on the slope, so that the specific effect and degree of slope ecological restoration can be reflected comprehensively, objectively and quantitatively.

Description

technical field [0001] The invention relates to the technical field of geological disaster prevention and control, in particular to the technical field of slope ecological restoration monitoring. Background technique [0002] Slopes refer to all exposed slopes related to engineering activities, which are divided into natural slopes and artificial slopes. my country is a mountainous country, so large-scale slope excavation will inevitably be involved in the construction of large-scale infrastructure such as roads, railways, reservoirs, mines, water conservancy and hydropower. The huge construction project broke the original force balance and ecological environment landscape of the slope, seriously damaged the soil and vegetation along the line, and formed a large number of exposed slopes. These steep, exposed, and abandoned slopes can easily cause geological disasters such as collapses, landslides, and mudslides, and even threaten human life. [0003] Under the guidance of ...

Problems solved by technology

However, compared with the wide application and rapid development of engineering technology, the current evaluation research on the effect of slope ecological restoration is still relatively backward, and there are many problems and deficiencies, such as the lack of quantitative index data for evaluation indicators, the lack of modern information technology support for evaluation methods, and the timeliness of evaluation. Lack of continuous tracking and monitoring, lack of mutual feedback between evaluation results and engineering practice, etc.

[0006] The monitoring of vegetation growth status in the process of slope ecological restoration has the following characteristics and difficulties: first, high slopes are steep and have great safety hazards, and it is not suitable to use measures such as artificial climbing for plant surveys; second, compared with ordinary crop monitoring, Slope plants should not only pay attention to parameters such as plant coverage, but also pay attention to the comprehensive restoration of the slope ecosystem, that is, pay attention to the combination of trees, shrubs and grass and the degree of integration with the surrounding environment; third, due to the poor site conditions of the slope, it is necessary to When sowing, the principle of matching pioneer plants and native plants is adopted, and more management and maintenance measures are required after spraying
