“…Loess geomorphy is the predominant geomorphological type in the Loess Plateau, largely formed through aeolian accumulation and water erosion processes, resulting in unique landforms [33], such as loess tablelands, hills, and ridges, as well as welldeveloped gullies. It is approximately 4~6 km/km 2 , as estimated from 1:50,000 topographic maps [33,34]. Therefore, we selected 13 groups of multi-scale contour clusters of loess geomorphy for this study.…”

“…Gully density refers to the lengths of gullies per unit area, and the greater its value, the more the watershed cuts into the geomorphology. Therefore, gully density is one of the most important indicators to represent regional geomorphic features [33], and can be used to measure the distance similarity between valley line hierarchical trees. Due to the fact that the drainage area remains unchanged after contour generalization; therefore, the distance similarity degree (S Dis S 2 S 1…”

This paper aims to propose a new approach to calculate the quantitative relations between morphostructural similarity degree and map scale change in multi-scale contour clusters for automatic contour generalization. Terrain lines were extracted by pre-processing of unclosed contour lines, and an indirect quantitative expression method of morphostructural similarity relation was proposed based on terrain line hierarchical trees. Thirteen groups of multi-scale contour clusters with different drainage areas of loess geomorphy were employed to explore the changing regularity of morphostructural similarity indices with map scale. Finally, the quantitative relations between morphostructural similarity degree and map scale change were calculated using 52 groups of points. The results show that power function is the best fit among the candidate functions, and the quantitative relations between the morphostructural similarity degree and map scale change can be expressed using the same power function, which facilitates the automation of contour generalization.

The Jiangnan region of China boasts a superior natural environment, and the combination of cities and mountains that form its historical landscape give it unique attributes. Local chronicles serve as an abundant source of information for visualizing this historic environment. This study aims to achieve two objectives: (1) to use digital humanities methods to process textual information in local chronicles, and (2) to visualize the historical relationships formed by the mountains and cities. In this study, we chose Suzhou, Zhenjiang, Jiaxing, Huzhou, and Songjiang in the Jiangnan region during the Qing Dynasty as our research sites. Through textual analysis and data visualization, we classified and reconstructed the historical spatial patterns of cities and mountains. As a result, our study provides a reproduction of the past spatial relationship between cities and mountains in the Jiangnan region during the Qing Dynasty. The research findings indicate that natural mountains play multiple roles in shaping the historical urban environment, particularly in terms of cultural images, notably the symbolic function they hold. The preservation of the urban natural environment, as seen through the vantage point of the historical landscape, is a critical component in contemporary urban development. The digital humanities methodologies utilized within this paper can be extended to other cultural heritage research, based on pre-existing local historical literature.
