Problems solved by technology

The traditional mathematical methods that form the basis of science, especially the calculus method, are limited to continuous smooth behavior and cannot be effectively used in the case of sudden change
Therefore, it is difficult to scientifically judge which areas should be timely intervened and which areas should be withdrawn safely

Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0076] Such as figure 1 , the evaluation method for timely intervention and safe exit of ecological restoration in the southern red soil erosion area provided by the embodiment of the present invention includes the following steps:

[0077] S101: Select soil quality, slope, vegetation cover, water and soil loss, and accessibility of human activities as data sources for mutation models; select organic matter, total nitrogen, available nitrogen, total phosphorus, available phosphorus, total potassium, available potassium, pH, bulk density and <2μm clay mass fraction is used as the soil quality factor; 88 sample points are s...

Abstract

The invention belongs to the technical field of environmental protection, and discloses an assessment method of timely intervention and safe withdrawal of ecological restoration in a red soil eroded area of southern China. The assessment method includes establishing a cusp catastrophe model, judging an ecosystem state, determining spatial dislocation of ecological restoration measures, dividing timely intervention and safe withdrawal areas of ecological restoration measures, and proposing an adjustment mode of the ecological restoration measures. The invention adopts a critical internal variable to determine an upper leaf and a lower leaf of the stable ecosystem state, and adopts the environmental change to determine the direction of the catastrophe ecosystem state; and the built catastrophe model can reveal the internal mechanism which cannot be disclosed by the traditional methods. Based on the basic framework of the invention, according to a research region and a research purpose, indexes can be adjusted according to the actual situation, and then the catastrophe model can be used for any other similar region in the red soil eroded areas of the south and can be used as an earlywarning system of the ecological restoration degree and the development trend.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an evaluation method for timely intervention and safe exit of ecological restoration in southern red soil erosion areas. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Ecological restoration often has a dislocation of ecological restoration measures, that is, the failure of ecological restoration measures to intervene in a timely manner leads to continuous deterioration of the ecology, and the failure of ecological restoration measures to withdraw in time leads to a large waste of funds. If timely intervention and safe exit cannot be correctly judged, a large amount of funds will be wasted or even play a negative role. The timely intervention of ecological restoration measures means that the ecosystem has been in succession stagnation or retrograde succession for a long time...
