摘　　要：通过对近年来乌鲁木齐地区的大地测量数据的综合分析处理,探讨了乌鲁木齐及周边地区现代地壳运动的特征。乌鲁木齐地区由于被众多的断裂所分割,且各部位受力极不均匀,西南部地区活动较东部显著。同时研究也表明,乌鲁木齐周边地区垂直运动速率较大,断裂近期运动比较活跃,有可能是中强地震发生的危险区段。This article discusses the characteristics of modern crustal motion in and around Urumqi through analysis by synthesis with geodetic data in recent years. And we conclude that southwestern Urumqi is more active than its eastern part because Urumqi is divided by many faults and each part suffers from uneven forces greatly. Also, it is shown that, the vertical movement rate in and around Urumqi is higher, the recent fault movement is relatively active, and moderate earthquakes will occur there possibly.
