采用综合震源机制方法，利用5002条P波极性数据反演黑龙江地区二维应力结构，求得该区0.5°Í0.5°综合震源机制解。初步研究表明：21世纪以来，构造应力场总特征基本一致，具有明显的继承性，主压应力和主张应力的优势方向明显，与板块运动关系具有成因上的联系。

We Used the Heilongjiang of 5002 P wave polarity data to inverse two-dimensional stress structure and 0.5Í0.5 focal mechanism solutions by the composite focal mechanism method。The preliminary study shows that: the tectonic stress field characteristics is uniformity since twenty-first Century, it has obvious inheritance, the predominant direction of the main pressure stress and tensile stress is evident, it is the relation of origin with plate movement。
