Ensemble Belief Rule-Based Model for Ecological Security of Land Resource Evaluation

Ecological security of land resource (ESLR) evaluation is a significant part in ecological environment protection and sustainable development. In order to consider the multiple influencing factors comprehensively, obtain a traceable and interpretable evaluation result, an evaluation process of ESLR based on the Ensemble Belief Rule-Based (Ensemble-BRB) model is proposed in this paper. The Ensemble-BRB model is a combination of several weak BRB models, each of which evaluates the ESLR from part of the influencing factors. Weighted averaging is introduced as the combination method to integrate the evaluation results of different weak BRB models. An ESLR evaluation case in Hunan Province, China is investigated to validate the feasibility and efficiency of the proposed method. The evaluation results can support the decision makers to develop targeted protection measures of land ecological.
