摘要： The ocean has become a new theme of the world economic competition.The development of marine industry is an inevitable measure to stabilize the sustainable and healthy development of China’s national economy.As a leading industry of marine economy,marine tourism has great potential for development.Marine tourism products are the foundation and power source of marine tourism development.The optimization of tourism products plays the most direct and key role in the upgrading of tourism industry.Shanghai,located in the center of Yangtze River Delta,is one of the most developed regions in China.However,with the increasing competition in the tourism market,the development of marine tourism is inevitable.This paper analyzes the general situation of marine tourism resources and the development status of tourism products in Shanghai,and probes into the specific countermeasures for the upgrading of its products,so as to promote the high-efficiency development of marine economy in Shanghai.

摘要： With the aim of understanding the fog chemistry in a Chinese megacity, twenty-six fogwater samples were collected in urban Shanghai from March 2009 to March 2010. The followingparameters were measured：pH, electrical conductivity (EC), ten inorganic major ions (SO42-,NO3-, NO2-, F-, Cl-, Na+, K+, Ca2+, Mg2+, NH4+) and four major organic acids (CH3COO-, HCOO-,C2O42-, MSA). The total ionic concentration (TIC) and EC of fog samples were one or two ordersof magnitude higher than those often found in Europe, North America and other Asian countries.Pollutants were expected to be mainly from local sources, including factories, motor vehicleemissions and civil construction. Non-local sources such as moderate-and long-range transport ofsea salt also contributed to pollution levels in fog events as indicated by back-trajectory analysis.The pH of the fog water collected during the monitoring period varied from 4.68 to 6.58；acidicfogs represented about 30.8%of the total fog events during this period. The fog water wascharacterized by high concentrations of SO42-(20.0%of measured TIC), NO3-(17.1%), NH4+(28.3%) and Ca2+(14.4%). SO42-and NO3-, the main precursors of fog acidity, were related toburning fossil fuels and vehicle emissions, respectively. NH4+, originating from the scavenging ofgaseous ammonia and particulate ammonium nitrate and ammonium sulfate, and Ca2+, originatingfrom the scavenging of coarse particles, acted as acid neutralizers and were the main cause for therelatively high pH of fogs in Shanghai. The ratio of (SO42-+NO3-)/(NH4++Ca2+) was lower than 1,indicating the alkaline nature of the fog water. A high ratio of NO3-/SO42-and low ratio ofHCOO-/CH3COO-were consistent with large contributions from vehicular emissions that producesevere air pollution in megacities.

摘要： Beginning with the basic characters and connotations of the international financial center，this paper analyses the effect of futures markets in the construction of Shanghai International Financial Center. The development of the futures market can enhance the characters of Shanghai which will be an international financial center，meanwhile，under the historical background in which the key implication of modern international financial center changes from the capital center to the pricing center，the development of futures markets with the function of price discovery could be helpful to Shanghai in obtaining the pricing right，pushing the construction of Shanghai International Financial Center forward.
