Riparian zone ecological remediation measure suitability assessment method

Abstract

The present invention belongs to the ecological technology field, and relates to a riparian zone ecological remediation measure suitability assessment method. The method comprises: status assessment of a riparian zone to be remedied, construction and systemization classification of an ecological remediation measure library, division of a riparian zone type regions and primary election of remediation measures, determination the dominant function of the riparian zone and optimization of the primary election measures, and obtainment of a final suitability remediation measure in the view of site conditions of the riparian zone. The method provided by the invention can consider development of other functions of a riparian zone while ensuring the development of the dominant function of the riparian zone; and a suitable riparian zone ecological remediation measure euphemistically saves the economic cost. The suitable riparian zone ecological remediation measure avoids the problem that empirical remediation measures are not suitable for the riparian zone functions and the site conditions to cause that the tree species cannot grow or loss of effect of the tree species is generated within a short time; and moreover, the suitable riparian zone ecological remediation measure can improve the flood prevention and slope stabilization and dam reinforcement capability, reduce side slope water and soil loss, improve soil, improve water quality and provide habitats for animals and plants.

Description

technical field [0001] The invention belongs to the technical field of ecology, and relates to a method for evaluating the suitability of ecological restoration measures in riparian zones. Background technique [0002] At present, as the transition zone between the terrestrial ecosystem and the aquatic ecosystem, the edge effect of the riparian zone of the river is obvious and the soil moisture content is high. Since ancient times, most of the villages or towns have been distributed along the river, which is not only conducive to domestic water intake, but also greatly promotes the development of planting, breeding and tourism. Humans have not protected the riparian zone while utilizing the river riparian zone, which has caused serious damage to the river riparian zone. The ecological restoration of the riparian zone can firstly ensure the stability of the river bank and maintain the shape of the river channel; secondly, it can ensure the ecological, landscape, buffer, and ...

AI Technical Summary

Problems solved by technology

[0004] Some scholars have proposed that the ecological restoration of the riparian zone should take into account both the function of the riparian zone and the definition of the structure of the riparian zone, such as whether there are dams, slope positions, etc., but they have not determined the order of the function and structure of the riparian zone, mostly based on the single function or structure Empirical selection of remediation measures based on conditions

[0005] For the research on the suitability of ecological restoration measures in the riparian zone, most scholars focus on the proposal that the ecological restoration measures in the riparian zone need to meet the following requirements: 1. Aim at flood control and ecological benefits, taking into account economic benefits; 3. Combination of engineering measures and plant measures; 4. Coordination with the surrounding landscape; 5. Pay attention to the principles of landscape effects, but lack of reasonable steps to determine the most suitable ecological restoration measures

[0006] Although scholars and the government are paying more and more attention to the ecological restoration of the riparian zone, more emphasis is placed on the evaluation of the construction benefits after the construction, and there are no good steps to define the measures required for the ecological restoration of the riparian zone before construction.
