摘　　要：本文根据断裂的活动习性，断陷盆地、平原、海湾的形成机理，地壳形变场，震源机制解，现今强震等烈度线长轴方向和 ＧＰＳ观测资料，初步探讨了福建地区晚更新世以来的构造应力场。结果表明，本区除了受到太平洋－菲律宾海板块向ＮＷ方向的挤压作用外，还受到来自印度板块向 Ｎ向 Ｅ的挤压。在这两种挤压作用中，后者大于前者。This paper preliminary discusses the characteristics of geotectonic stress field since Late Pleistocene period based on the habits of fault activity, formative mechanism of the fault pitfall basin, plain and bay, crustal deformation field, interpretation of the earthquake focus mechanisms, long axial direction of the earthquake intensity isopleth in the nowadays strong earthquake and GPS survey data. The result shows that the extruding has been subject to the Pacific-Philippines Sea Plate in the NW direction except, and because the Indo Plate in the N and E direction, too. Between the two extrudings the Pacific-Philippines Sea Plate and Indo Plate, the Pacific-Philippines Sea Plate had greater impacts.
