摘要 河流水力侵蚀模型(stream-powerincisionmodel)常被用来分析山脉地形是否达到均衡.蓬莱运动的弧陆斜碰撞使得台湾岛造山带的山脉呈现成长的前均衡(南部)、均衡(中部)、崩塌的后均衡(北部)等三个不同演育阶段的地形.利用基岩河道的坡度(S)与集水面积(A)的关系来分析台湾岛造山带的河流可得到此三种状态的山脉地形特征.分析结果发现,台湾岛中央山脉东西两侧的S-A图呈现直线型态,显示基岩河道的河床高程不随时间改变(dz/dt=0),S-A直线的斜率与其截距分别与均衡地形发育的时间和地体抬升率的大小有关.而台湾岛造山带的南部与北部之S-A图则分别呈现上凸与下凹的型态,显示基岩河道的河床高程分别随时间成长(dz/dt>0)与降低(dz/dt<0),它们的切线截距仍可反映地体的抬升率.
