为定量分析高原地区连续驾驶时间和海拔高度对驾驶员特性的影响，利用biofeedback 2000 x‐pert生物反馈系统，实地检测高原地区驾驶员连续驾驶时各项生理、心理指标。通过相关性分析，选取相关性最高的心率变异低频成分建立模型。通过回归分析建立连续驾驶时间与LF值的关系模型以及海拔高度与LF的关系模型，最终建立连续驾驶时间、海拔高度、心率变异低频成分三维模型，并通过检验。研究结果表明：海拔高度的增加会加速驾驶员进入疲劳状态，随着年龄的增长，驾驶员受到海拔高度的影响也会变大。

In order to quantitative analyse the impact of continuous driving time and altitude on drivers on plateau areas ,the research group gauged drivers’ physiological and psychological indexes on plateau areas with biofeedback 2000 x‐pert system . Through correlation analysis of all the indexes with continuous driving time and altitude ,the research group found LF has the highest relativity with continuous driving time and altitude in all the indexes .As this result ,LF was selected as the index to build up models .By building models of continuous driving time with LF and altitude with LF ,the three‐dimensional model about continuous driving time、altitude and LF was set up and got through the inspection .This research shows that the increase of altitude will accelerate the drivers’ fatigue and the driver will be affected more with the increase of age .
