研究白龙江流域断裂构造活动与滑坡分布及发育关系对认识滑坡形成与防治具有重要意义.通过对白龙江流域断裂构造特征总结，结合野外调查，发现白龙江流域以武都为界，以北断裂为北西向，以南为北东向；断裂活动经历了加里东、海西、印支、燕山和喜山期，其中海西和印支期断裂活动最为强烈，燕山和喜山期继承了前期构造活动方向，构造应力场以北东?南西向挤压和北西?南东向拉张为主.利用ArcGIS缓冲区分析发现白龙江流域滑坡分布与断裂构造的相关性较高，在距断裂2.5 km范围内滑坡数量占滑坡总数的70.6%.同时发现在白龙江上游，滑坡(群)位于逆冲断层的上盘，岩石中平行和垂直断层走向的节理发育，有利于岩石破碎和软弱结构面的形成，逆冲上盘的正断层活动增强了滑坡形成的可能性，因而，白龙江流域断裂构造活动控制着滑坡的发育和发生.

A study of the relationships between the distribution and development of landslides and faults activities is of great significance to understanding the formation and the prevention of landslides. An analysis made of fault features combined with field investigations in the Bailongjiang Region showed that the fault trends were of the NW direction in the north of Wudu but of the NE direction in the south and the faults activities took place in the Caledonian, Hercynian, Indosinian, Yanshanism and Himalayan periods. Of them the Hercynian and Indosinian were the periods when faults strongly developed, and in the Yanshanism and Himalayan periods the faults inherited previous tectonic directions. Basically, the tectonic stress field is compressive in the NE-SW direction and extensive in the NW-SE direction. Our ArcGIS buffer analysis uncovered that the correlation between landslide distribution and faults is higher in this area: within a scope of 2.5 km the faults accounted for 70.6% of the total landslides. In the upstream of the Bailongjiang region, the landslides (landslide clusters) are located in the hanging-wall of the thrust fault, joints in parallel and perpendicular to fault strikes have developed in rocks which tend to have cracks and undergo formation of weak structure planes, and the normal fault activations within the hanging-wall of the thrust faults haved intensified the probabilities of the landslide formation. Thus the fault activities also control the landslide development in the Bailongjiang region.
