Spatial distribution of the transportation demand in the western region based on the transportation network;

The paper analyzes the present situation,problems and causes of the lower validity on transportation demand forecast in china with the ideas,principles and methods of system sciences.

In order to establish a scientific transportation forecasting system and accurately get to know the forecasting theory in transportation demands,it is necessary to re-discuss the implications in the transportation demands and supplies.

Based on the analysis of the construction condition of San Du Ao Port Area of Ningde Port,port construction and local economic development,port orientation and container transport demands,as well as the interrelationship between them,this paper puts forward the orientation of development,scale and construction scheme of the starting project,and suggestions for further work to be done.

Through a comparison of transport demand and transport quantity,a concept of the potential transport demand floats out.

On the questions of the inland river transportation under the modern material circulation and countermeasures;

Based on analyzing the problems of cargo transportation in inland waters, the paper indicates that transport structure should be adjusted to develop and boom the inland water transport.

Therefore,it is of great significance to the research on the evaluation and method of inland water transport supply.

Vigorous development of the inland water transport has given effective solution to this problem, but it has also brought many negative impacts.

The European Union, with the aim of resolving the problem of structural overcapacity in the fleets in inland waterway transport and incapability of the increase in demand in this sector to absorb this overcapacity, on 27 April 1989, commenced to carry out the measures of structural improvements in inland waterway transport.
