In ancient China, where was frequently troubled by invaders, the government set up many beacon towers for alerting and transmitting military information along the border and the coast. Many beacon sites still exist in some areas, which are generally located in dangerous places with high mountains and rough terrain, bringing great difficulties to archaeological discovery. Therefore, it is particularly important to develop a predictive model applicable to the distribution of mountain beacon sites. Taking 68 beacon sites found in Wenzhou as research samples, this study used the superimposed method of logistic regression and viewshed analysis, forming a high-precision, scientific and operational predictive model for the distribution of beacon sites, which was verified by the cross-validation method. The results showed that the beacon site predictive model simulated in this study could reduce the probability scope of site location by 90% compared with the common logistic regression predictive model, which greatly improved the accuracy and ability of site prediction. At the same time, it could also be used to understand the relationship between the known sites and their surroundings to assist in decision-making about conservation and management.
In 2013, Chinese president, Xi Jinping, announced the Belt and Road Initiative (BRI) to his audience in Kazakhstan. He stated that this will involve the construction of roads, railways, and even special trade corridors, among others along the ancient Silk Road in a bid to foster economic, political, and social relationship between China and partner countries. This paper focuses on analyzing how leading newspapers in Nigeria, Malaysia, and Vietnam, namely The Sun, Vanguard, The Punch, The Nation, NewStraits Times, Malay Mail, Business Insider, The Star, Saigon Times and Vietnamnet Bridge, have framed and communicated this multi-national project to their various audiences six years after Xi's announcement. Working on 200 editorial contents published between May 2017 and March 2019 across the selected newspapers, this explores how they framed BRI. We found that while most of the reports have framed BRI positively, others are framed to reflect cautious optimism. We suggest that BRI managers should take necessary steps to engage the media, policy makers, and other stakeholders to properly educate them on the vision and mission of the initiative.

There are many subjective inferences regarding environment-related studies in modern studies of ancient military defense heritage, and the objective quantitative analysis of citadel site selection and layout has become the key to interpreting the environmental adaptability of citadels under defense strategies. Based on this, it has been proposed in this research that the site selection of ancient military citadels in a specific region (Zhejiang) has environmental adaptability characteristics. Firstly, an elevated hydrological overlay model was established by predicting and graphically verifying the ancient hydrological thresholds through geospatial analysis strategies. Secondly, the hydrological and topographical indicators of the regional environment where the military citadel is located were digitally extracted. Finally, correlation and weight influence calculations were performed for different environmental data. The environmental adaptability characteristics of the site layout of the Ming dynasty-era Zhejiang coastal defense military citadel, based on military defense needs, were obtained. In this way, we promote digital technology for the excavation, conservation and sustainable use of heritage resources.
