Abstract:

Tectonic geomorphology is the result of interaction between neotectonics and exogenic geological process at the basis of rock, which is also the most intuitional information carriers reflecting neotectonics. Tectonic geomorphologic parameters are the quantitative expression of the morphological features of landform generated by internal forces, showing great potential in quantitative uncovering neotectonics. Based on tectonic landform evolution^,s sensitive impact on tectonic uplift, geomorphic characteristics of river and hillslope gradually become ideal information carriers of neotectonics. This paper analyzed the application principles of river geomorphologic parameters based on stream-power incision model, and introduced the latest research about the hillslope geomorphologic parameters corresponding to tectonic uplift delayed response reported by Martin D. Hurst et al in 2013, and tried to discuss the parameters^, indicative significance to tectonic uplift. It comes to the conclusion that tectonic geomorphologic parameters can preferably reflect neotectonics information implicated in tectonic geomorphology. Acquiring these parameters in different time can realize the dynamic study on modern tectonic geomorphic process to get the latest information of crustal activity. However, tectonic geomorphic research cannot settle geochronological sequence of tectonic activity, and is hard to eliminate the impact of nontectonic factors. Nowadays, the application of tectonic geomorphologic parameters in neotectonics is still a “bottleneck” in qualitative study. Integrating tectonic geomorphologic parameters with geologic and geomorphic records and experimental simulations to build a comprehensive model of geomorphologic parameters is the most efficient path to realize the quantification of neotectonics research.
