RESEARCH ON SPATIAL FIELD EFFECTS ON YRV OF INBOUND TOURIST FLOWS IN SHANGHAI CITY
利用空间场理论分析1998-2007年上海及长江流域各省数据，发现上海入境旅游流的空间场效应增强但辐射作用弱于集聚作用，且对浙江、江苏影响最明显，能量重心东移。
It is necessary to study on the tourism transit ability of metropolis and tourism flow in linear region.As the basic existence of tourist activities,the tourism field has energy,momentum and quality.With the analytical method of the energy,potential energy,and regional structure from the spatial field theory,the international visitor arrivals statistical data and sampling survey data from 1998 to 2007 of Shanghai city and the provinces of the Yangtze River Valley(YRV) have been analyzed,indicated that there is a enhanced trend in the spatial field effect while existing difference in influence in the various provinces.The effect of inbound tourist flow in Shanghai province is stronger than its radiant effect.The centralized and decentralized inbound tourist flow in Shanghai city is unevenly distributed in YRV,and it is obvious to Zhejiang and Jiangsu.The regional center of gravity of the energy has a tendency of shifting to the east,and the regional structure of field energy tends to be rational.Shanghai should play a strategic leading role,to play its tourist flow accumulation and radiation functions,with a view to the whole Yangtze River Valley comprehensive benefits of the rapid increase.
