Research on the Countermeasures of Smart Tourism Construction in Sanya Under the Background of Free Trade Port Construction

By analyzing the current situation of smart tourism construction in combination with the actual tourism situation in Sanya,this study aims to find out the problems existing in the current smart tourism construction and understand the various factors affecting the smart tourism construction in Sanya.Then,relevant theories and practical applications were used to study the ways to carry out smart tourism construction with the help of policy,location,and other advantages to meet the needs of the development of the times.Based on the study,practical countermeasures and suggestions were given to provide reference for the construction of smart tourism,ensure the continuous improvement of smart tourism construction,and help the upgrading and transformation of tourism in Sanya.Based on the analysis of the construction and data of smart tourism and tourism informatization in Sanya,this article has formed a useful method to help Sanya build an international tourist island and a modern smart tourism city using the Hainan Free Trade Port construction policy.

China’s Participation in Port Construction in the Western Indian Ocean Region:Dynamics and Challenges

In recent years,China has actively participated in port construction and development in the Gulf and East Africa.China’s investment and construction of ports in this region demonstrates the mutually beneficial cooperation between China and the host countries,serves the regional development and the overall interests of China-Arab and China-Africa cooperation,and reflects the characteristics of letting one case guide a whole area.China’s investment in port construction is faced with the risks of port politicisation and security problems brought about by the geopolitical game of world major powers.It is necessary for China to take the Western Indian Ocean region as a whole,to attach importance to the coordination and cooperation between the Gulf and East Africa in terms of geo-economy,channel route security and port construction layout,and pay attention to reducing the risks of port politicisation and security.

Design and Construction of The Great-West Dyke in Lianyungang Port

The The Great-West Dyke with a length of 6.7 km, the largest sea wall in China, was completed in June, 1994. This paper introduces structure options of nibble mound sea wall on soft foundation and a new type of armour block-hexagon multihole block (HMB) and a new method of treatment for soft foundation by using underwater explosion. Construction practice of some projects in China shows that by using this method good effect of treatment and marked economic benefit can be achieved by using this method.

Dayaowan Harbour Construction Project in Dalian Port

Located at the southern end of the Liaodong Peninsular, Dalian seaport has ideal natural conditions with a deep-water and ice-free port. As a vast harbour, this port is the hub of the waterways from north to south of China, playing a key role in the transport of import and export goods for the provinces of northeastern China and the vast eastern part of Inner Mongolia.

Study on the Marine Sedimentary Environment Evolution of the Southern Laizhou Bay Under the Impact of Port Projects

The southern Laizhou Bay is mainly composed of silt-sandy coasts with diverse landforms, and its marine hydrodynamic environment is sensitive to human activities. Marine hydrodynamic and sedimentary environments of the study area have changed under the influence of large-scale port projects in recent years. In this paper, the evolution of hydrodynamic environment, deposition rate, and geochemical characteristics were studied based on sediment grain size, element analysis and ^(210)Pb dating of two cores, in order to analyze the influence of Weifang Port on marine environmental evolution, and provide theoretical and practical basis for protecting marine environment in developing marine resources reasonably. Results showed that sediments of the two cores were relatively coarser and mainly composed of silty sand. Sediments above 230 cm in core WF1 and 218 cm in core WF2 were deposited since 1855 when the Yellow River appeared to deposit its sediments within the modern active delta, and the average deposition rate was between 0.3 and 0.5 cm a^(-1). Implement of Weifang Port projects in 1997 and 2007 created great influence on the sedimentary environment evolution in the surrounding waters, and the deposition rate was significantly increased. The average annual deposition rates were 5.1 cm and 3.5 cm in WF1 and WF2 respectively between 1997 and 2007. Content of heavy metals in sediments showed no obvious change in the vertical, indicating that the heavy metals were less affected by human activity and there was no significant accumulation of such metals in the study area.
