【摘要】 基于事前评价过程和自然界生物进化过程的相似性,提出了系统结构、系统结构模式和系统环境模式矩阵的概念,并根据系统结构、系统结构模式与系统环境模式矩阵的适应程度,建立了模式评价决策模型,制定了评价系统的评价分类准则,并对评价系统作了一定的理论分析.将此模型和方法应用于城市生态安全评价中,通过与模糊综合评价法的比较,表明了该评价模型和方法的优越性.更多还原

【Abstract】 In this paper,according to the similarity of the process of evaluation in advance and the process of creatures’ evolution in nature,the concepts of system structure,schema of system structure and the matrix for schema of system environment are presented.An schema-based appraising decision model is established according to the adapting degree of system structure and schema of the system structure to the matrix for schema of the system environment,the appraising classification criterion is also formulated,and some theoretical analysis for the appraisal system is made.This model and method are applied to the evaluation of the ecological security for city,and by contrast with fuzzy comprehensive assessment,the superiority of the appraising model and method is indicated.更多还原
