摘　　要：目的:植物神经功能状态的参数异常是心血管疾病预后不良的标志。本研究拟提出一种基于层次分析法定量评价植物神经系统活动度及平衡性的新方法。方法:通过层次分析将心率变异性参数分为时域参数、频域参数、非线性参数3层指标,根据各层指标的两两相对重要性构造判断矩阵,计算出各层指标的权重,经过一致性检验验证判断矩阵的可靠性。经过自身对照实验获得数据对模型进行验证。结果:随着应激程度的增加,交感神经张力呈增加趋势,副交感神经张力呈降低趋势,两者的平衡性呈增加趋势。结论:本研究设计的模型能一定程度上反映植物神经系统的变化,有一定的理论研究价值。Objective The abnormal parameters reflecting the functional status of autonomic nerve can be regarded as a marker of poor prognosis of cardiovascular diseases. Based on the analytic hierarchy process, a quantitative evaluation method is proposed for assessing the activity and balance of vegetable nervous system. Methods By means of hierarchy analysis, heart rate variability parameters were divided into time domain parameters, frequency domain parameters and nonlinear parameters. The judgment matrix was constructed according to the relative importance of each index, and then the weight of each index was calculated.The consistency test verified the reliability of the judgment matrix. Finally, the data obtained from self-control experiment were used to verify the proposed model. Results With the increase of stress level, sympathetic nervous activity increased;parasympathetic nervous activity decreased; and the balance of sympathetic nervous activity and parasympathetic nervous activity increased. Conclusion The designed model which can reflect the change of vegetable nervous system has certain theoretical research value.
