But specific studies on middle and small size coastal cities, especially on northern small coastal cities, have not yet been made sufficiently.

Analysis of growth characteristics of environmental engineering geological problems in littoral cities;

Littoral cities are the most developed regions in economy in our country.

It is important and essential to study the engineering geological characteristics of rocksoil masses in littoral cities for guiding engineering construction in the future.

According to forming factors of urban tourist image, this paper analyses the basis for how to create tourist image of coastal city and initially probes into the creating principles of tourist image of coastal city in China.

According to the characteristic of coastal city s tourism, the system of precaution and emergency rescue decision for touring safety accidents of coastal city is set up by integrating 4s (GIS, GPS, CS, and ES) technique and TIS (Tourism Information System).

Since the start of the economic boom,the rate of growth in this area has exceeded the expectation and Fuzhou,with her fantastic natural resources——both in sea and in the rivers,has shown a tendency to shift her weight of city building from riverside city nearby to the seaside city;as a city-planner.

In the last few years, takes the latent tourism development the important resources- The seaside city becomes the important object the traveling professional studies.

Regional differentiation of environmental engineering geological problems is coastal cities;

Evaluating the tourism competitiveness of the coastal cities quantitatively and comparing their differences will provide important guiding function for the coordinating of the relationship between cooperation and competition among the tourisms of the cities in the area.

It is crucial to coordinate the relationship between cooperation and competition of urban tourism by comparing the difference of coastal cities tourism competitiveness.
