Traditional villages in the Mid-Spine Belt of Bea.jpgul China are abundant in tourism resources and have a high tourism value. Conducting tourist flow study helps to promote the preservation of traditional village tourism resources and rural revitalization in the MSBBC. Based on online travel data, ArcGIS and social network analysis techniques were used to examine the network structure features and the spatial and temporal distribution of the traditional village tourist flow in MSBBC. Findings indicate that short- and medium-term tourism dominates the tourism flow in traditional villages in MSBBC in terms of temporal distribution, with notable seasonal variations. The Yunnan village of Shuanglang serves as the hub of the entire geographical distribution pattern of the tourism flow. Three categories may be used to categorize the geographical distribution patterns seen in various provinces: “single-core and multipoint,” “dual-core and multipoint,” and “multi-core and multipoint.” The traditional village tourist flow network density in MSBBC is low. Traditional village tourism nodes have a rather loose link with one another, and they rely on non-traditional village nodes. Core nodes mainly belong to “mixed core type”, has no significant radiative effect on the edge node.

The open government movement has promoted the open sharing of government data around the world, and how to make better use of government open data to promote political democracy and social progress has become an urgent issue for discussion.Bibliometric analysis was conducted to explore the research context, cooperation, research hotspots and development trends of domestic and foreign scholars on government data openness since 2000. CiteSpace knowledge graph was used to conduct a comparative study on government data openness at home and abroad. It is found that foreign government data openness has better integration of different disciplines and a higher degree of data utilization, and has begun to try to apply a.jpgicial intelligence to the government data openness platform. Given the domestic and foreign comparison results, the following suggestions are put forward for the opening of domestic government data: strengthen the integration with a.jpgicial intelligence, strengthen the efficiency of data utilization and integration with other discipline systems, and finally sink from the government to the citizen side.

E-commerce channels are a crucial means for Xinjiang fresh apricots to expand market sales and improve efficiency. Analyzing market reputation based on E-commerce review texts can provide valuable market feedback for promoting the development of the Xinjiang fresh apricot E-commerce industry. Consumer reviews of Xinjiang fresh apricots from e-commerce platforms were collected and preprocessed. Subsequently, an in-depth analysis and mining of the review texts were conducted, including determining the sentiment orientation of the review corpus, extracting review themes based on the LDA (latent Dirichlet allocation) topic model, and quantitatively evaluating consumer reputation based on dependency syntax analysis and sentiment calculation. The study shows that consumer reviews of Xinjiang fresh apricots are predominantly positive. The three core themes extracted are fruit quality, logistics speed, and product price. Consumers are most concerned with the attributes of fruit taste and logistics speed, with the highest satisfaction in fruit sensory quality, general satisfaction with logistics, and the lowest satisfaction with price. Based on the research results, development suggestions were proposed for the fresh apricot e-commerce industry.

Wenshan Prefecture has unique natural and cultural tourism resources. It is of great significance to clarify the spatial distribution characteristics and influencing factors of A-level tourist attractions in Wenshan Prefecture for promoting global tourism and optimizing the spatial layout of local tourism. Taking Wenshan Prefecture as an example, the spatial distribution characteristics of A-level tourist attractions in Wenshan Prefecture was analyzed by using the nearest neighbor index and nuclear density analysis methods based on ArcGIS platform, and tries to explore the factors affecting the distribution of tourist attractions. The results show that in terms of spatial distribution, the A-level tourist attractions in Wenshan Prefecture are more in the north than in the south, and less in the east than in the west. It is concentrated in low-lying areas with an altitude of 1 000~2 000 m. The nearest proximity index is R=0.710 187 and R<1, indicating that the point elements of A-level scenic spots tend to condense and distribute, and Puzhehei Scenic spot is the core area of 5A scenic spots. The geographical detector explains that the spatial differentiation of A-level tourist attractions in Wenshan Prefecture is most influenced by rivers and topography. The interactive detection results show that the spatial differentiation of A-level tourist attractions in Wenshan Prefecture is influenced by multiple factors, which play A synergistic role in enhancing the spatial layout of the scenic spots.

The terrain and geological conditions in the mountainous area of western Sichuan are complex and changeable. Dangerous rocks are mostly developed in high and steep slope sections, which pose a serious threat to the safety of highway traffic after collapse. Taking the tail perilous rock of Qiaoqi Reservoir in Baoxing County of Ya’an City as an example, the basic characteristics of perilous rock were analyzed by means of UAV aerial survey and field investigation. Rocpro3 D software was used to simulate the three-dimensional kinematics to evaluate the collapse damage. The results show that the formation of dangerous rock in the working area is caused by the combined action of tectonic compression, rainfall erosion and weathering unloading. Strong rainfall and strong earthquake are the typical causes of dangerous rock collapse. The maximum impact energy after the collapse of dangerous rock in the working area is more than 5 000 kJ, and the removal of large-size dangerous rock can effectively reduce the impact energy value. After the collapse of the dangerous rock in the working area, it shows the stage motion characteristics of rolling along the slope → bouncing after hitting the road surface near the surface of the 351 national highway → stopping the accumulation of the riverbed and bank slope of the East River. The treatment scheme of dangerous rock removal+passive protection network+open hole+frame anchor rod can be used for prevention and control.

In order to objectively evaluate the county geological disaster risk information and provide an effective research basis for disaster prevention and reduction, the risk assessment was mainly carried out in the key research area of Kuancheng Manchu Autonomous County. Based on the data of field investigation, previous research and ArcGIS spatial software analysis results, AHP(analytic hierarchy process)-information method was adopted to select 11 evaluation factors for classified evaluation of key research areas, so as to ensure the objectivity and accuracy of the research. The research results comprehensively evaluated the impact factors from the three aspects of people, land and comprehensive vulnerability, and completed the detailed analysis of the main risk factors, risk coverage and key risk areas in the county. It is found that the areas with high risk of geological disasters are mostly concentrated in the villages and towns in the north of the county, covering a wide area, and the geological conditions of the risk areas are poor and seriously affected by rainfall. The vulnerability of disaster-bearing bodies is directly related to the production, life and property safety of residents. Most of the carriers are located in towns and mountainous areas, which belong to disaster-prone areas in this risk assessment, and should be paid attention to in disaster prevention and prevention.

The social discount rate (SDR) is a critical parameter of investment appraisal and alternative scheme comparison. Through solving stochastic differential equation, a reference formula of measuring the SDR was presented by means of the equivalent return on stock investment and the long-term interest rate. With the data of the main western economies for set by some countries concerned,the SDRs are checked to match the results of the calculation. Such a test proves the feasibility of this approach. In the process of empirical analysis, it is found that there is the quadratic nonlinear regression correlation between the interest rate and the inflation rate, which raises question on the traditional linear rule of determination of the interest rate.

Selecting the relevant data from 2012 to 2021, the economic collaborative development level of each subsystem of Shenyang Modern Metropolitan Area, Liaoning Coastal Economic Belt, and the composite system of “One Area and One Belt” of Shenyang and Dalian was analyzed by measuring the economic correlation degree, order degree and synergy degree of cities. The results show that the economic connection intensity between Shenyang and its peripheral cities is relatively strong, while that of Dalian and its peripheral cities is relatively weak. The order degrees of each subsystem of Shenyang Modern Metropolitan Area and Liaoning Coastal Economic Belt both show a decreasing and increasing process, and the orderliness is developing continuously for the better. The synergy degree of the composite system of “One Area and One Belt” of Shenyang and Dalian is in a good synergy state, but there is still room for improvement. In the future, it is necessary to start from strengthening the radiation and driving effect of core cities, improving the orderliness of the development of each subsystem, promoting the linkage development of “One Area and One Belt” of Shenyang and Dalian, and optimizing the overall design, to improve the regional economic collaborative development level of Liaoning Province.
