SPATIAL MORPHOLOGICAL CONCEPTUAL MODEL OF BAY

摘要

Located in the conjunct part of sea area and land area, the morphology of bays is complicated and is changing seriously by the mutual action of natural and artificial factors. Therefore, the scientific and systematic description of bay is rather difficult. The research of the spatial morphological conceptual model of bays is meaningful for the representation of the bay and the construction of digital bays. Furthermore, it is also important for the change monitoring, exploitative intensity evaluation, as well as the further use of the bays. Nevertheless, the correlated research is rather less. A multi-scale expression model of bay is put forward in the paper. Firstly, the general morphological model of the bay which is in a bay-range scale is abstracted by Geometric Abstract according to the characteristics of bays, and then in the coast scale, five categories of coasts--rocky coast, silty coast, sandy coast, artificial coast, and other type of coast were classified, a coast-range scale model of the bay based on these categories were proposed. Finally, through the construction of the spatial morphological conceptual model of the several typical bays--Daya Bay, Zhelin Bay and Jiaozhou Bay, the validity of the conceptual model is verified.
