Abstract: In recent years, it has been found that the palaeogeographic features will be accelerated when a strong tectonic activity exists. However,it is difficult to reconstruct the palaeogeography and palaeogeomorphy related to this tectonic activity by applying the traditional methods. Based on many previous research work,the Basin and Landscape Dynamics(Badlands)software,a parallel algorithm,is thus developed to simulate the spatial and temporal evolution of palaeogeomorphy. It can be used to study the evolution of surface processes,to predict erosion and sedimentation rates,and to evaluate sediment fluxes. Therefore,this software is powerful in conducting more detailed research on the reconstruction of palaeogeography and palaeogeomorphy. In this paper,the basic principles and methods of Badlands are introduced. This software is used in the reconstruction of Mesozoic geomorphology and geological evolution in the southern East China Sea Continental Shelf. First of all,the Early Mesozoic palaeotopography is built by using the pre-existing seismic profiles,well logging data,and cross-section balanced profiles in the study area. Parameters, including rainfall,rock erosion,sea level change,dynamic topography and crustal elastic layer thickness, are input in the numerical model to analyze the influence of strong tectonic movement on the evolution of basin and geomorphology in the study area. The simulation results show a good consistency with the known Mesozoic geomorphological and sedimentary features. We further analyze the distribution of sedimentary during the evolution of basin and the three-dimensional Mesozoic palaeogeography and geomorphological evolution. This method can also provide a new way to analyze the basin fill processes and the exploration of energy resource and mineral.

摘要: 近几年来的研究发现,当存在较强的构造活动时,古地理特征变化将会加快,而常规方法很难对这一构造活动过程中的古地理和古地貌进行有效的恢复和研究。Basin and Landscape Dynamics(Badlands)软件正是基于前人的研究工作而开发的一款数值模拟软件,用于模拟各种空间和时间尺度的地貌演化。它可用于研究地表演化过程、预测侵蚀和沉积速率并评估沉积物通量,从而实现对古地理和古地貌进行更为精细化的研究。笔者介绍了Badlands软件的基本原理和方法,并将此方法应用于东海陆架盆地南部中生代地貌及地质演化过程的研究: 首先利用研究区域内现有的地震剖面、测井、平衡剖面等资料获得中生代早期的古地形;再通过恢复的古地形构建数值模型,并加载降雨量、岩石侵蚀性、海平面变化、动力地形调整和地壳弹性层厚度等相关参数进行模拟研究,以分析强烈的构造运动对盆地地貌演化的影响;最后对比模拟结果与已知的中生代的地貌特征和沉积分布,并据此进一步分析中生代盆地演化过程中的沉积物分布规律以及三维古地理和古地貌演化特征。该方法可以为沉积盆地充填过程分析和能源矿产勘探提供有益的思路。
