摘　　要：提出一种见解:即如国内有的学者指出的,在龙门山之西,鲜水河之东存在一个刚硬地块——若尔盖地块。而正是川滇地块与若尔盖地块以及四川盆地等地块的相互运动和作用才引发了汶川地震。由此,还提出对这几个地块今后的动态和形变监测应予重视的建议。Seeing some home scholars pointed out that in the west to the Longmenshan mountain and in the east to Xianshuihe River there exists a rigid block--Ruoergai block, the author puts forth an academic opinion that just the Ruoergai block＇ s （but other block, e. g. Kunlun block） movement and the actions among it with the Chuandian block and Sichuan basin resulted in the Wemchuan earthquake on May 12,2008. From this,a certain suggestion for strenthening monitoring the movement of these related blocks is put forward as well.
