What is Fuzzy Comprehensive Evaluation in Ecosystem Health?
Fuzzy Comprehensive Evaluation (FCE) in Ecosystem Health applies fuzzy set theory with membership functions and weighted aggregation to assess multi-factor ecosystem conditions under uncertainty.
FCE models integrate indicators like water quality, biodiversity, and soil health into holistic indices for ecosystems such as rivers and wetlands. In Vietnam-related studies, FCE combines with entropy weighting and AHP for robust evaluations (Zhong et al., 2021; 141 citations; Xu et al., 2020; 41 citations). Over 10 papers since 2015 apply FCE to environmental health diagnostics.
Why It Matters
FCE enables precise diagnosis of ecosystem degradation in urban and agricultural areas, informing policy for sustainable management (Song et al., 2015; 41 citations). It handles vague ecological thresholds, vital for Vietnam's wetland restoration and river basin planning (Shan et al., 2020; 19 citations). Applications include groundwater risk assessment supporting public health interventions (Zhong et al., 2021).
Key Research Challenges
Weight Determination Bias
Subjective weights in FCE lead to inconsistent ecosystem health rankings across studies (Shan et al., 2020). Entropy and AHP methods mitigate but require hybrid approaches for balance. Objective weighting improves reliability in river health models.
Handling Nonlinear Interactions
FCE struggles with complex, nonlinear ecological dynamics like pollutant synergies (Xu et al., 2020). Membership functions often oversimplify vague boundaries in wetlands. Integration with PCA enhances factor extraction.
Scalability to Regional Data
Adapting FCE index systems to Vietnam's diverse ecosystems demands localized indicators (DENG Xiaojun et al., 2013). Data scarcity limits model validation. Set pair analysis hybrids address uncertainty in sparse datasets (Wu et al., 2019).
