Table 1 Common methods for assessing ecosystem stability
Methods | The main content |
|---|---|
Fuzzy Comprehensive Evaluation Method: | A comprehensive evaluation method based on fuzzy mathematics theory. This method combines qualitative and quantitative indicators, using fuzzy sets and membership functions to perform fuzzy quantification and processing of uncertain evaluation indicators. |
Gray Relational Analysis | A multi-factor statistical analysis method based on gray system theory. It evaluates the state of the object at a certain stage concerning a predetermined target, allowing for an assessment of the object’s performance under various factors. |
Analytic Hierarchy Process (AHP) | A decision-making method that decomposes elements related to the decision into multiple levels, such as goals, criteria, and alternatives. Based on this hierarchy, it conducts both qualitative and quantitative analysis to assist in decision-making. |
Ecological Model | A scientific concept involving computational models used in the field of ecology to analyze and evaluate ecosystem health, stability, and biodiversity. |
Pressure-State-Response (PSR) Model | A method used to measure the pressure, state, and response of ecosystems. Pressure refers to the impacts of human economic and social activities on the environment. State refers to the environmental quality and health of the ecosystem at a specific time. The response indicates how humans act to mitigate, halt, restore, and prevent the negative impacts of human activities on the environment. |
Emergy Analysis | A method used to assess the energy usage and conversion efficiency in natural and human-made systems. It converts different forms and sources of energy into a unified measurement standard, typically in solar energy units. |
Markov Dynamic Evaluation Model | A model uses probabilistic Markov chains to predict future states based on current conditions. It’s widely applied in ecological studies for modeling species dynamics, land use changes, and succession, providing insights into long-term stability and trends through stochastic transitions. |
