摘要

众所周知，沟蚀会影响土壤生产力，限制土地利用，并对世界许多地区的基础设施构成威胁。冲沟侵蚀在很大程度上被忽视了，因为它是�对其效果进行建模和可视化。许多冲沟迅速长大，使有效的技术控制成为可能�狂热且往往过于昂贵。为了评估土壤和基质对冲沟侵蚀的敏感性，必须确定触发因素�并进行了分析。在本研究中，基于试验流域的地形特征、土壤特性和测得的径流，用Python模拟了冲沟随时间的发展。全模拟GIS在南非Kwatunzi地区的一个冲沟上进行了测试。这些结果非常有希望，可以对冲沟演化的时间序列进行2D/3D可视化。

A GIS-based simulation and visualization tool for the assessment of gully erosion processes

Gully erosion is known to affect soil productivity, limit land use, and to pose threats on infrastructure in many parts of the world. Gully erosion has been largely neglected because it is di�cult to model and visualize its effects. Many gullies grow rapidly to large sizes, making effective control technically di�cult and often too expensive. To assess the susceptibility of soils and substrates to gully erosion, the triggering factors must be identi�ed and analyzed. For this study, a simulation of gully development over time was implemented in Python based on the topographic characteristics of the test watershed, soil properties, and measured runoff. The full simulation GIS was tested on a gully in the KwaThunzi region, South Africa. The results are very promising and allow a 2D/3D visualization of the time series of gully evolution.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
