机场噪声问题日渐突出，研究减噪飞行程序减小机场噪声的影响范围与强度显得非常重要。该文以厦门高崎机场为例建立机场噪声预测模型，采用计权等效连续感觉噪声级作为评价指标，使用Java编程完成噪声值计算及大地坐标转换，使用ArcGIS软件结合地理信息绘制噪声等值线，分析不同爬升梯度下减噪起飞程序产生的噪声影响范围。结论表明，该方法可以量化噪声影响范围，克服传统机场噪声曲线绘制方法的局限性。

Airport noise problems have become increasingly prominent,it is important to use noise abatement flight procedures to reduce the scope and strength of airport noise exposure.The article took LWECPN as noise index,established Xiamen airport noise prediction calculation model,calculated predictive noise value and drew noise contour line by ArcGIS software,analyzed the impact of takeoff procedures on aircraft noise.Conclusion shows that noise abatement take-off climb procedures have some influence on takeoff noise;the method can overcome the limitations of traditional airport noise curve drawing.
