Study On Influence Law Of Water Transportation Development On Wuhan Urban Spatial Evolution In Modern Times (1861-2009)

Today, the reason that Wuhan can become the central city of the central region is definitely on count of its historical water transportation. The transportation affects the land price and the use through changing space's accessibility, thus causes evolution of the urban space. The traffic is one of the major affect factors for the urban space evolvement, and the water transportation is also the important component of the transportation, therefore the water transportation will make influence to the urban space evolution.This dissertation first analyzes the modern Wuhan water transportation influences to the urban space evolution as the background. According to the modern Wuhan's external transportation structure in various times, the connection degree of each constitution factor and the transportation historical characteristics, the dissertation division the times into three stages, from the open of the Hankow port to many kinds of transportation way competition development today's Wuhan external communication, as: the modern water transportation time, the portage time and the fast stereoscopic comprehensive transportation time. According to the development condition characteristics of the modern Wuhan water transportation in various times, it divides the modern Wuhan water transportation into three main stages:the prosperous stage, the decline stage and the special stage.Then the dissertation studies the regular pattern of the modern Wuhan water transportation's influence to its urban space, mainly by means of the relative scale change and the expansion pattern change. The expansion relative scale change law--as the status drop of the water transportation (has nothing to do with the prosperity and decline condition of the water transportation longitudinal development), from the open of the Wuhan port to today's high speed development of the socialist market economy, the urban space expansion relative scale have the tendency of getting smaller under the water transportation's influence. In the future it will continue to reduce gradually, but if only the water transportation exist, cannot this expansion relative scale be eliminated. The regular pattern of expansion pattern change--as the status drop of the water transportation (has nothing to do with the prosperity and decline condition of the water transportation longitudinal development), under the water transportation influence's urban space expansion pattern changed from the ribbon development pattern abuts the main city when the port opened to the group expansion pattern which away from the main city.Then the dissertation researches the regular pattern of the modern Wuhan water transportation to the city spatial structure influence, mainly by means of the land function structure and the relation of the port-city. The regular pattern of the land function structure--as the status drop of the water transportation (has nothing to do with the prosperity and decline condition of the water transportation longitudinal development), the category of the urban space land utilization has the tendency of the simplification under the water transportation influence (from the all-embracing when the port opened to today's merely only the large scale industry land and near port industry land). The regular pattern of the port and city's spatial relations--along with the urban and the water transportation's development, the port city relations are compelled changed from the integrative condition to the discrete state, and the port space and the main city's distance has a more and more farther tendency. The relation of the harbor and the urban will be weaken gradually, but the relation of the harbor and the region will be strengthen progressively.Finally, according to this dissertation's the influence law, it forecasts the urban space expansion based on the water transportation influence--in the Wuhan city circle, the water transportation will certainly form a series of small cities far away from the main city along the Yangtze River, and these small cities' function will be quite unitary.
