    Abstract: 台灣西南部麓山帶地殼變動速率活躍,本計劃在分析台灣西南部泥岩地區二仁溪流域的5
    The foothill belt of southwestern Taiwan is characterized by its relatively fast crust
    deformation. While analyzing the DEM of 5 meter high resolution of the Erjen basin in the
    mudstone area in southwestern Taiwan, we found that the DEM should be “modified” to erase the
    man-made landscape such as bride, road, and highway. Then the software will be able to generate
    the river drainage automatically and correctly. The result of sinuosity analysis shows that sinuosity
    will increase while river running across the Lungchuan fault, Gutingkeng fault, and Gutingkeng
    anticline. This means that these structure lines contain certain activity. The result of analysis of
    Stream-power incision model shows that S-A plots of the drainage located in the footwall of the
    structure lines have concave form systematically. But S-A plots of the drainage running across the
    structure lines and hangwall have convex to straight form. This means that in the mudstone area,
    typically the post-steady state topography mainly causing by erosion process, uplift process of
    activity structure lines will also let it locally appear pre-steady-state to steady-state topography.
