中文摘要：

基于World Stress Map（WSM）计划与GPS观测结果,利用最小二乘配置方法对中国大陆及周边应力方向和应变率场进行了研究,结果表明二者分布总体一致,在青藏地块东部存在一定差异,应力方向表现为近NE向而GPS主压应变率表现为近EW向;另一差异区域位于西域地块西部,应力方向表现为自西向东由NW向NE的转变,GPS主压应变率以近NS向为主。

英文摘要：

On the basis of World Stress Map（WSM） plan and GPS velocity field data we studied the stress orientation and strain rate in the Chinese mainland by using the least squlares collocation method. The results show that the two fields are consistent in general, but there are differences in the east part of Qinghai-Tibet block, in which the orientation of stress is near NE-word and that of strain raete is EW, and another difference region which locates in the west area of the Xiyu block whose stress orientation presents from NW to NE, with general direction is from west to east and the GPS principal compressive strain rate is mainly near NS.
