| 摘 要： | 云南北北西地震条带西起中甸、保山，跨越洱源-鹤庆断裂、程海断裂、红河断裂、曲江断裂、澜沧江断裂以及小江断裂等主要活动断裂，止于云南东部的寻甸、弥勒，其上共有17个GPS观测点。通过对这17个测点进行复测，并以2001年观测资料作为背景，获取了观测区域内地壳水平形变速率、地应变、面膨胀等信息。结果显示，滇西的永胜、洱源、下关、南涧一带地壳差异运动最强烈，其次是滇南的通海、建水地区。

| Abstract: | The NNW Seismic Belt of Yunnan begins from Zhongdian-Baoshan west of Yunnan, crosses the Eryuan-Heqing fault, Chenghai fault, Honghe fault, Qujiang fault, Lancangjiang fault and Xiaojiang fault, and ends at Xundian and Mile east of Yunnan, on which there are 17 GPS observation stations. Through the repeated measurement for them, and taking the data in 2001 as the background, some information such as the horizontal deformation rate of the crust, strain and surface dilatation are obtained in the observing region. The results show that the strongest different movement of the crust happened in Yongsheng, Eryuan, Xiaguan and Nanjian in West Yunnan, and the next is in the Tonghai and Jianshui area. |
