It has become a universal " iron law" in the development history of the world powers to rise to the sea and fall behind it. It is a pioneering undertaking for China to build a characteristic maritime power,which could not " simply replicate" and " forcibly graft" the customary pattern of the western traditional maritime powers formed in hundreds of years.A number of experiences accumulated by the world's traditional maritime powers in the historical process of " going to the sea" are worth summarizing and learning,and it will give us a lot of historical enlightenment.展开更多

Therefore, in order to do this, surveys are performed and by contingent valuation (CV), the willingness-to-pay (WTP) is estimated. The best estimation points out that tourists are willing to pay 24.4 dollars around each year, and by means of such estimation, it is estimated that the cultural service’s economic value to preserve raised beds is between US$ 3000 and US$ 3700 per hectare. Such found value must be used as another input for decision makers when dealing with projects and/or policies facing contrary purposes. The analysis is innovative in the sense that there is almost no CV literature to estimate the economic value of historical scenic beauty.展开更多

However, due to their highly dy- namic nature, global river plume areas have not yet been determined for use in synthetic studies of global oceanography. Based on global climatological monthly averaged salinity data from the NOAA World Ocean Atlas 2009 （WOA09）, and monthly averaged salinity contour maps of the East and South China Seas from the Chinese Marine Atlas, we extract the monthly plume areas of major global rivers using a geographic information system （GIS） technique. Only areas with salinities that are three salinity units lower than the average salinity in each ocean are counted. This conservative estimate shows that the minimum and max- imum monthly values of the total plume area of the world＇s 19 largest rivers are 1.72× 106 kin2 in May and 5.38× 106 klTl2 inAugust. The annual mean area of these river plumes （3.72× 106 knl2） takes up approximately 14.2% of the total continental shelves area worldwide （26.15 × 106 km2）. This paper also presents river plume areas for different oceans and latitude zones, and analyzes seasonal variations of the plume areas and their relationships with river discharge. These statistics describing the major global river plume areas can now provide the basic data for the various flux calculations in the marginal seas, and therefore will be of useful for many oceanographic studies.展开更多

In this article, we propose exploring its potential for historical research over long periods. Here, we present a Historical GIS (HGIS) of the railways of Europe for the period 1830-2010. This is a response to the need to carry out spatialtemporal analyses in order to evaluate the territorial impact of the railway and its influence on the distribution of population. The main objectives of this work are: to publicise the existence of this spatial database;to explain the approach followed in order to produce it;and to highlight some of the results that have already been achieved by using it. To date, the possibilities offered by HGIS have hardly been explored in research into the territorial impact of the railway. Similarly, until now, little work has been done in this area at the European scale. The most innovative aspects of this HGIS therefore lie in the methodology used and the subject treated.展开更多
