在探讨各类气象要素与通用机场选址联系的基础上，对西北地区通用机场选址气候论证中关键气象评估指标及其重要程度进行了分析研究，并利用2000～2009年平罗气象站和2011～2012年沙湖机场临时气象站观测资料，采用统计诊断分析方法对石嘴山沙湖通用机场场址的气象条件进行了分析评估。研究结果表明：风速、风向，能见度，天空云量、云状、云高等是西北通用机场选址需要重点考虑的气象要素。根据气象要素在通用机场选址中所起的功用和重要程度，西北通用机场选址气象评估指标大致可以划分为6大类。其中，Ⅰ～Ⅲ类指标是场址能否建设通用机场的决定性关键气象指标；Ⅳ、Ⅴ类指标是评估机场场址未来运行效率、工程设计、投资成本的重要参考指标；Ⅵ类指标主要用于特殊场址评估。石嘴山沙湖机场场址区域全年盛行风向明显，风速以低风速为主，大风天气少，能见度状况优良，雷暴、冰雹和沙尘暴等恶劣天气少，天空低云少，且低云中层积云、积雨云和碎积云所占比例低，月降水少，最大温差变幅小，具备作为通用机场场址的良好气象条件。

Based on investigating the connections between the various meteorological elements and the general airport site selection,the key meteorological evaluation indexes for general airport site selection in northwest China and the important extent of these indexes were analyzed.Then,the Shahu general airport proposed site was evaluated by using the observational data from Pingluo weather station dur-ing 2000-2009 and the temporary weather station observational data from 201 1 to 2012 in the proposed site.The results show that wind speed,wind direction,visibility,cloud amount,cloud form and cloud height are the important meteorological elements that need to be considered in site selection of the general airport in northwest China.Meanwhile,the meteorological evaluation indexes of the general airport site selection can be roughly divided into six categories.Among them,the indexes of class I-III are the critical indexes which decide whether or not to build the general airport on the proposed site,and the indexes of class IV and V are the important refer-ence indexes for the proposed site’s operation efficiency evaluation,engineering design and the investment calculation,while the class VI is mainly used in the special proposed site evaluation.The Shahu general airport proposed site has the prevailing wind direction,low wind speed,excellent visibility conditions and the less thunderstorm,gale,hail and sand storms,while there is less low cloud in the sky,and the percentage of the cumulostratus,cumulonimbus and cumulus fractus is just 24.9% in all of the low cloud.Meanwhile, the monthly precipitation is little,and the monthly variation of maximum temperature difference is also small.Considering the above factors,the Shahu general airport proposed site has the good weather conditions as a general airport site.
