“…Before the 1960s, due to the broken terrain, steep terrain, sparse vegetation coverage, frequent rainstorms, and irrational reclamation of sloped farmland, there was a large area of soil erosion in the study area. The erosional sediment transport modulus of the basin ranges from 2110–71 100 t/(km 2 ·a), and the average erosional modulus is 15 780 t/km 2 (Liao et al, 2009).…”

The channel sediment transport capacity is an important parameter in soil erosion models, and it determines the proportion of soil erosion that is sent outside the watershed. However, the calculation and judgment methods for the sediment transport capacity of channel are still incomplete, and further research is needed. Therefore, this paper takes Chabagou, a typical watershed in the hilly and gully region of the Loess Plateau, as an example and, based on the measured hydrological and sediment data collected during rainstorm floods in 1961–1969 at three hydrological stations, Caoping, Shejiagou, and Tuanshangou, studies the sediment transport capacity of channels in a small watershed from the perspective of energy dissipation. Clearly, the sediment transport capacity is better determined by using a single flood and sediment concentration peak process. The discriminant conditions are determined for the sediment concentration to reach sediment transport capacity during the flood rising and falling sections of the sediment process of the small watershed storm flood. When determining sediment transport capacity based on the characteristics of the flood and sediment concentration peak, we find that sediment transport capacity is reached in the flood discharge peak when the flood discharge peak occurs earlier than the sediment concentration peak. When determining sediment transport capacity based on the flow discharge and sediment concentration characteristics of the sediment fall section, we find that when the flood event exhibits a counterclockwise hysteresis curve and a time‐lagged effect occurs, the sediment concentration at that time reaches sediment transport capacity. In this study, the sediment concentration as a function of run‐off amount is logarithmic at different subbasin scales when run‐off reaches its maximum capacity to transport sediment. The R2 is high, ranging from 0.78 to 0.92. The results of this research provide a reference for the study of sediment transport capacity.

With the rapid urbanization of China in recent years, urban development has entered a new stage that focuses on improving the quality of growth. During this process, the excessive emphasis on economic growth and the neglect of spiritual and cultural aspects have led to various issues, such as cultural homogenization and urban identity crises. This study examined the development patterns behind this phenomenon by focusing on land specifically designated for urban cultural functions. Through the lens of cultural urban land use (CULU), a comparative study was conducted between the ancient city of Xi’an and the emerging city of Shenzhen. The study collected and processed point of interest (POI) and area of interest (AOI) data from both Xi’an and Shenzhen and analyzed the spatial characteristics of CULU using quantitative statistical methods. The analysis revealed multidimensional differentiation between the two cities in terms of value characteristics, historical characteristics, functional characteristics, and social consensus characteristics. Furthermore, the study applied the Spatial Circle Layer model (SCL) to analyze the spatial distribution differences in these characteristics between Xi’an and Shenzhen and identified key factors influencing these characteristics, such as the “formation and spatial distribution of key CULU” and the “historical continuity of urban space”. These findings were synthesized into the “anchoring–layering mechanism”. Our research explores why land designated for urban cultural functions exhibits different patterns in different cities, providing effective theoretical support for the planning and construction of such land in future urban development.
