结合GNSS和黑龙江地区定点形变观测，分析日本2011年3月11日M_W9.0地震对黑龙江地区地壳形变的影响，结果显示：日本Mw9.0级地震引起哈尔滨站、绥阳站震后两年内运动速率明显增加（哈尔滨增大4mm/年；绥阳站速率增大6mm/yr）；定点应变与GPS观测到的同震效应至少在4个台站多种仪器观测均具有很好的一致性；日本M_W9.0地震不仅引起区域水平向应变变化，而且也对垂直向产生一定影响；长基线变化反映出日本3.11地震引起的大空间应变变化与黑龙江地区长期构造应力场背景一致，3.11地震可能对黑龙江地区地表应变积累有增强影响。

We study the changes of the Heilongjiangregion crustal deformation caused byJapan9.0 earthquake combining GNSS and fixed deformation observation. The result shows that the earthquake increase the speed of GNSS site movement including HRBN and SUIY than before（HRBN from25mm/yr to29mm/yr;SUIY from26 mm/yr to34mm/yr）coseismic step observed by fixed deformation and GPS have consistency in the horizontal direction at least at four sites by several observation instruments .The earthquake cause strain variety not only in the horizontal direction but also effect the vertical direction. Long baseline time series varieties indicate large scale space strain change andHeilongjiangregion tectono-strain field background have consistency and 3.11 earthquake may accelerate the region's surface strain accumulation.
