Method and device for determining primitiveness of natural ecosystem

By calculating multi-dimensional indices of ecological structure, processes, functions, organisms, and disturbances, and combining them with ecological environment characteristic zoning, and using high-structure authenticity areas as reference benchmarks, this approach solves the problems of single assessment dimensions and neglect of regional differences in existing technologies, and achieves a scientific and efficient assessment of ecosystem authenticity.

AI Technical Summary

Technical Problem

Existing technologies for assessing ecosystem authenticity are limited by their single dimension, neglect of regional differences in natural benchmarks, lack of a multi-factor integrated framework, inability to accurately capture embedded disturbances, and lack of zoning evaluation methods that combine climate zoning or ecological location.

Method used

This paper provides a method for determining the authenticity of natural ecosystems. By calculating the ecological structure authenticity index (SAI), ecological process authenticity index (PAI), ecological function authenticity index (FAI), biological and indicator species authenticity index (BAI), and human disturbance intensity index (ADI), a comprehensive natural ecosystem authenticity index (ACI) is constructed. The method is then used to divide the ecosystem into zones based on ecological and environmental characteristics, and areas with higher structural authenticity are used as natural reference benchmarks to assess the authenticity of processes and functions.

Benefits of technology

It achieves multi-dimensional comprehensive assessment and dynamic benchmark identification, accurately captures the intensity of artificial landscape embedding, improves assessment sensitivity, and the assessment results are highly consistent with the actual protection status, providing a scientific basis for national park planning and nature reserve management.

Abstract

The invention discloses a natural ecosystem primitiveness determination method and device, and relates to the technical field of ecological assessment, and the method comprises the steps: obtaining land utilization data of a research region, and calculating an ecological structure primitiveness index; recognizing a natural reference area based on the ecological environment subarea and the ecological structure primitiveness index; obtaining ecological system service data, and calculating an ecological process original truth index and an ecological function original truth index based on the natural reference region; acquiring species distribution data, and calculating biological and indicator species protogenicity indexes; obtaining human activity data, and calculating a human interference intensity index; and finally, carrying out normalization and weighted fusion on the indexes to obtain a natural ecosystem original comprehensive index. According to the method, the problems that an existing evaluation method is single in dimension, neglects regional natural reference difference and lacks a multi-factor comprehensive framework are solved, and the scientificity of natural reserve management is remarkably improved.
