Huizhou villages are representatives of traditional villages and have a high historical, cultural, and tourism value. In view of the problems of low commercial efficiency due to the small scale of commercial space and the imperfect layout in Longchuan Village, Jixi County, Xuancheng City, Anhui Province, this research explores the spatial advantages of Longchuan Village’s commercial layout through an analysis of street and lane space syntax and a commercial space resistance model. The research on the spatial syntax of streets mainly focuses on the analysis of the spatial accessibility, line-of-sight integration, and spatial comprehensibility of Longchuan Village’s streets. The commercial space resistance model mainly studies the attraction of tourism resources to tourists in order to select the most suitable area for the layout of commercial space. The results of the analysis show the following: (1) The integration degree of traffic and the sight line is relatively high at County Road and Water Street in Longchuan Village, so these two places have better accessibility and more sight lines. (2) Longchuan Village has a good spatial understanding in a small area, so it is not suitable to distribute commercial space but rather to centralize it. (3) In the commercial space layout resistance model, the area around Water Street and Qixing Pond has the smallest spatial resistance and the greatest opportunity for population gathering, making it the most suitable for a commercial layout. On the basis of the analysis results, this paper puts forward an optimization strategy of Longchuan Village’s commercial space layout in a targeted manner to help Longchuan Village achieve a better commercial layout. The research contribution of this paper will help planners and architects to take advantage of space to plan the commercial space of traditional tourist villages so that they can exert a better commercial value and tourism effect and to promote the tourism development of traditional villages across the country.

Exploring the occurrence of shale oil is of guiding significance to the exploration and recovery of shale oil. However, most studies focus on adsorption and neglect absorption or study it independently, which weakens the understanding of the coupling relationship between adsorption and absorption and the occurrence mechanism of shale oil in kerogen and its associated pores. Based on molecular dynamics (MD) simulation, the kerogen matrix with a smooth surface is constructed, and the general amber force field is adopted to calculate the adsorption and absorption of shale oil in a type II kerogen slit, and the influences of temperature, pressure, and pore diameter on the occurrence of shale oil are also discussed. Molecules absorbed in the kerogen matrix are mainly retained in the free space formed by the accumulation of aliphatic carbon. The effects of temperature on the distribution of shale oil in adsorption and absorption are opposite. High temperature improves the desorption of molecules from the adsorption sites and causes a lower adsorption and greater absorption. In contrast, pressure and pore diameter only slightly influence the distribution of shale oil. Unexpectedly, the result under aqueous conditions shows that the shale oil was absorbed quickly before the formation of water clusters. Once the water clusters are formed due to the strong hydrogen bonding and adsorbed near the N-, S-, and O-containing groups on the kerogen surface, the matrix gaps are blocked due to the size exclusion, and the absorption is suppressed. Additionally, we established the evolution of the ratio of free-adsorbed−absorbed oil at different temperatures and pressures, which provides a new idea and a new method for detecting the occurrence and mobility evaluation of shale oil under reservoir conditions.
