| 摘 要： | 川滇地区位于中东亚塑性流动网络系统东南部 ,研究区内岩石圈下层含右向网带 6条和左向网带 16条 ,受其控制在多震层内形成相应的地震带。多震层和岩石圈下层的构造应力场在总趋势上基本一致 ,进一步证明了下层网状流动对上层的控制。沿网带以不同交角展布的发震断裂组成地震构造带 ,其中多数右向地震构造带已发育成熟 (视成熟度Λ≥ 0 .8) ,而左向带除大理 -通海和腾冲 -景洪两带接近成熟外 ,多数的Λ值显著小于 0 .8。“川滇菱形块体”因塑性流动网络的存在和块体边界的变迁 ,其现今构造和动力学涵义有待探讨

| Abstract: | The tectonic stress field and seismic tectonics in the Sichuan Yunnan rhombic block and its adjacent areas are investigated in terms of the "plastic flow network and multi layered tectonic deformation" model for continental dynamics (for short, called "netlike plastic flow" model or NPF model). According to the model, it is presented that in consideration of the transition of deformation regime from brittle to ductile with increasing depth, the lithosphere is divided into several tectonic deformation la |
