Interpretation of Modern Shipping and Trade on Jinsha River
The hydrological characteristics of Jinsha River system,ferry distribution,the shape of ships and floating vehicles,the relationship between shipping and trade are investigated from the perspectives of geography,technology and economy.It can be found that the beneficiaries of the opening of Jinsha River shipping were not only the central government,local government,but also the merchants in Sichuan,Yunnan and Xizang provinces.A rough estimate suggests that at least 147 ferry crossings have occurred in the history of the Jinsha River basin.The trade of Sichuan-Yunnan East Road and West Road across Jinsha River takes ferries and docks as transport hubs and communicates with inter-county,inter-provincial and international trades through land-water combined transport,forming a regional market with local and ethnic characteristics.Today,due to the rapid development of highways and railways,a three-dimensional transportation network has been formed between cities,and the traditional functions of ferries,docks,and ports have been modernized and upgraded.However,in some areas,shipping still has the advantages of convenience,low cost,and heavy load.At the same time,some ancient ferry crossings have irreplaceably and non-renewably historical,artistic,and scientific values,and are important cultural relics resources that show China's 5000-year civilization history.Therefore,it is necessary to strengthen the protection of the ancient ferry crossing site,and consider establishing a water transportation museum and a site park to show the historical process of integrating the cultures of various ethnic groups in southwest China into Chinese culture,and to show the water landscape of the Southern Silk Road,thus constructing a southwest water signage system of Chinese civilization.
