Analysis of spatial patterns and driving factors of different ethnic villages under regional integration is important for the conservation and development of ethnic villages. This article takes seven multi-ethnic villages in the Dadu River Basin of Ganzi Prefecture as an example; we employ a quantitative model of spatial syntax based on the theory of figure–ground relationship to link the tangible and intangible spaces. The results reveal the logical context and formation mechanism among the overall layout, residential architecture, and public space of the villages. The findings of this study are as follows: (1) The site of different ethnic villages reflects commonality. (2) The spatial configurations of the villages are significantly influenced by the surrounding natural environment, with significant differences. Cluster-concentrated villages exhibit the smallest expansion trend, rich spatial levels, and strong ethnic territoriality; strip-intensive villages have the largest scale and the strongest permeability; and radiation-dispersion villages have variable expansion directions and architectural relationships among residents. (3) Both of the participants’ selection behaviors and residential spaces constitute the internal structure for the ethnic culture, which is driven by the humanistic spirit and force of social order, making the spatial morphology a diversified and multi-layered characteristic. (4) The rural space has gradually changed from a single residential unit to a complex unit with multiple functions. The findings extend the scope of research to ethnic villages in watersheds and provide a theoretical and practical basis for the development of other similar rural villages.

In China, tourism development is a crucial approach to poverty alleviation. With the consolidation of poverty alleviation achievements and the promotion of rural revitalization, it is of great significance to explore the relationship between tourism development and poverty alleviation from the perspective of multidimensional poverty. Therefore, this study took 28 key assistance counties for rural revitalization in the Sichuan–Chongqing region (hereinafter referred to as “key counties”) as the research objects, introduced NPP-VIIRS nighttime light (NTL) data, and a coupling coordination degree (CCD) model to explore the coordination relationship and mechanism between them. The results showed that from 2015 to 2020, the tourism development index (TDI) and estimated comprehensive development index (ECDI) of the key counties increased by 112.57% and 115.12%, respectively. In addition, the spatial differences in tourism development and multidimensional poverty both showed a narrowing trend. According to the results of the CCD model, the key counties basically faced coordination obstacles in the early stage, which were mainly transformed into reluctant coordination and moderate coordination in the later stage. This indicated that tourism poverty alleviation showed a coordinated development trend overall. However, the study also found that there may not be synchronicity between tourism development and poverty alleviation and analyzed the mechanism of their interaction. Overall, the study confirmed the positive impact of tourism development on alleviating multidimensional poverty. In addition, the study found that measuring multidimensional poverty based on NTL data has a high accuracy and can provide support for poverty research. These research results have an important reference value for China to carry out sustainable tourism poverty alleviation and comprehensively promote rural revitalization.

This study takes the urban area of Dujiangyan City as the research area, ten risk assessment factors are selected to conduct the fire risk assessment and analysis, including substations, building floor area ratios and miniature fire stations, and uses analytic hierarchy process, buffer analysis and overlay analysis. The minimize facilities model and maximize coverage model in location allocation model (LA model) are used to optimize fire station site selection. The research results show that there are still greater fire risks in the south and northeast of Dujiangyan City. The addition of two small and medium-sized fire stations in the north section of Yanhua road and in south section of Rainbow Avenue can basically realize to cover the areas with higher fire risks thoroughly.

This paper uses the Point of Information (POI) point of interest and population distribution feature data in Dujiangyan City as the basic data, and uses spatial analysis methods, such as nuclear density analysis, contour analysis and standard deviation ellipse, to study the correlation between the entity and virtual boundaries of Dujiangyan. The results show that the urban entity and online activity intensity of Dujiangyan spreads around Xingfu, Guankou, and Puyang. The entity boundaries of the city and the virtual boundary in these three areas overlap basically, except for the city of Dujiangyan. The entity and online activities are not balanced in intensity, and there are obvious dividing lines in the area near Longchi. The entity and virtual boundaries of the city are quite different in Qingcheng Mountain and Juyuan.

Public transportation issues are increasingly becoming a key constraint to the sustainable development of urban economic and social development. Based on crowd big data and GIS spatial analysis methods, this article analyzes the accessibility of the public transportation in Wansheng Economic and Technological Development Zone (hereinafter referred to as the development zone). A comprehensive evaluation and analysis was conducted to study the matching relationship between population density and existing public transportation stations, and to propose the optimal suggestions. The results show that the overall public transportation accessibility in the development zone is average level, and the public transportation accessibility is better in the densest crowded areas, but in the east and southeast of the development zone, crowd activities are poorly matched with the public transportation network, and residents’ travel demands can’t get public transportation with timely responses.

With the development of tourism and the acceleration of urbanization, tourist cities have sprung up like bamboo shoots. Large population flow and more cultural relics are the characteristics of the current tourist city, which brings greater fire risk. The current research pays little attention to fire safety problems in tourist cities. This article takes the urban area of Dujiangyan, a tourist city, as the research object, and uses the superposition tool of GIS to make a fire risk grade map with a total of 9 factors of regional characteristics and architectural characteristics superimposed by weight. The result shows that there are still many areas with high fire risk in Dujiangyan, such as the ancient urban area where tourists gather and the southwest sub-area of Dujiangyan urban area. Based on the positioning and distribution model, 6 new fire station layout points are selected, and the responsibility division map of 9 fire stations in Dujiangyan City is finally obtained, which provides a reference for the layout of fire stations in Dujiangyan City.
