庄浪河流域地貌发育的主要特点是:①水系型式为独特的白杨树形;②高级河道超长;③上游金强盆地内阶地类型以堆积为主,并广泛发育第四级高级阶地;下游阶地以基座为主,缺失第四级阶地;④上游地区发育有向东侧叠的洪积扇群。笔者认为,上述特点是青藏高原急剧隆起的产物。中更新世末高原边缘的地形大切割,导致庄浪河溯源发展,切穿金强盆地南缘的地槽褶皱山系,最终袭夺了古金强河,并切开古盆地堆积面,使其成为流域最高级阶地,此后便开始了现今统一的庄浪河水系演化过程。因此,认识上述特点对于区域地貌发展过程和新构造运动性质的研究是有其现实意义的。
The main features of the Zhuanglang River Basin landform development are: ① The water system is a unique poplar; ② The long channel is long; ③ The terraces in the upper Jinqiang Basin are dominated by accumulation and the fourth terrace is extensively developed; The terraces are dominated by pedestals, and the fourth terrace is missing. ④ The alluvial fan swarms eastward are developed in the upper reaches. The author believes that the above characteristics are the product of the sharp uplift of the Qinghai-Tibet Plateau. At the end of the Middle Pleistocene, the large topography of the plateau at the edge of the plateau led to the traceability of the Zhuanglang River, cutting through the geosynclinal fold system in the southern margin of the Jinqiang Basin, eventually capturing the ancient gold river and cutting the accumulation surface of the ancient basin Became the highest terraces of the basin, and since then it has begun the evolution of the unified Zhuanglang River system. Therefore, it is of practical significance to understand the above characteristics for the study of the development process of regional geomorphology and the nature of neotectonics.
