Wetland dynamic boundary determination method based on three elements of hydrology, plants, and soils

Abstract

The invention discloses a wetland dynamic boundary determination method based on three elements of hydrology, plants, and soils. The method comprises the following steps: step 1, extracting a wetland hydrological dynamic boundary; step 2, acquiring wetland vegetation data; step 3, acquiring wetland soil data; step 4, simulating a wetland vegetation and soil dynamic boundary according to the data in the step 1 to the step 3; step 5, determining a wetland dynamic boundary. According to the method, wetland dynamic boundaries under multiple dimensions can be comprehensively and accurately reflected.

Description

technical field [0001] The invention belongs to methods for defining the range of wetlands in subjects such as ecology, biology, and hydrology, and in particular relates to a method for determining dynamic boundaries of wetlands based on three elements of aquatic soil. Background technique [0002] Wetlands have huge ecological service functions such as flood regulation and storage, water purification, water conservation, and climate regulation. They are one of the ecosystems with the richest biodiversity, the highest productivity, and the most valuable. It provides an important guarantee for the survival and development of human beings. However, under the influence of high-intensity human activities and climate change, wetland ecological problems have become prominent. At present, interpreting the internal mechanism of wetlands, highlighting the existing problems and threats of wetlands, and proposing wetland management and ecological restoration suggestions are important ...

AI Technical Summary

Problems solved by technology

Due to the multiple characteristics and complex multi-level nature of wetlands, the boundaries of wetlands have dynamic characteristics in different dimensions, and there are differences in the boundaries of wetlands determined based on different elements, which brings great difficulties and uncertainties to the determination of wetland boundaries

[0004] At present, the methods for determining the boundary of wetlands at home and abroad mainly include identification methods based on wetland flooding characteristics, identification methods based on vegetation transition zones, technical methods based on hydrogeomorphological wetland classification, and identification methods based on remote sensing technology, but these methods only involve Water, soil, vegetation and other aspects, and there are shortcomings such as complex parameters and insufficient applicability
