摘　　要：以北京市密云县气象观测场为研究对象，关注其观测环境保护范围内新增建筑对观测环境的影响。首先对该区域观测环境进行分析，采用统计分析和城市小区尺度模式，得到了该区域相关气象要素（风）变化的结论。结论如下：①1959—2013年间，密云气象观测环境55年来的变化比较明显，其观测环境总体处于不断恶化的状态；②从流场来看，冬季新建医院对观测场区域比夏季有较为明显的影响，且影响范围也比夏季要大；③从风场来看，冬季小风时，观测场在有医院比没有时，其区域的风速升高了8％；夏季小风时，降低了10％；冬季大风时，降低了9％；夏季大风时，升高了8％。总体上医院对观测场的影响基本保持在9％左右。Miyun County, Beijing meteorological observation field for the study, observing environmental con- terns within the scope of its new building on the observation environment. First observation environment in the re- gion were analyzed using statistical analysis and urban district scale models, has been related to the area of meteor- ological elements （wind） change the conclusions. Its conclusions are as follows. ① From 1993 to 2012, the Miyun meteorological observation environment changes in the past 20 years is quite obvious, and its overall environment in observing the deteriorating state. ② From the flow field of view, the new hospital for observation field area in winter than in summer have a more significant impact, and the impact is larger than the summer range. ③ From the wind field of view, winter, small wind, the observation field where hospitals are better than no time, its regional wind speed increased by 8% ; summer small wind, it reduced by 10% ; winter winds, its lower 9% ; summer winds, it increased by 8%. In winter, the wind speed from small to large, the new hospital is to continuously make the ob- servation field area of the wind decreases, summer, wind from small to large, the new hospital is to continuously make the observation field area of wind speed increased.
