摘要
生态环境系统信息的不确知性导致了生态环境评价问题的复杂性。根据Zimmermann提出的参数化组合算子理论,建立多指标的生态环境质量评价模型,并采用免疫进化算法对模型参数进行优化,将优化后的参数化组合算子模型应用于河北坝上地区生态环境质量评价。结果表明,该模型评价结果与实际相吻合,并具有意义明确、计算简便和适应非线性问题等特点。
Inaccurate information knowledge in the ecological environment system,which lead to the complexity of the ecological environment evaluation problem.According to the parametriccombination operator theory put forward by Zimmermann,the ecological environment quality evaluation model of a multi-indicator was established,model parameters were optimized by immune evolutionary algorithm,parametriccombination operator theory after optimizing applied in the ecological environment quality evaluation in Bashang District Area in Hebei Province,the results showed that the model evaluation results were according with model evaluation results,and had the characteristics of distinct meaning,easy calculation and adapting to the non-linear problems.
