Research On The Utilization Of Qingda Coastal Zone And The Morphological Characteristics Of Near-shore Regions

Under the background of the coastalization process and the implementation of the land-sea coordination concept,the importance of coastal zone utilization and coastal regions research has become increasingly prominent.Qingdao,as a coastal city,shows uniqueness in the process of coastal regions development,spatial morphology evolution and current city layout.Urban development is closely related to coastal zone utilization.The change of coastal zone utilization mode fits the process of urban development and function adjustment in Qingdao.The high economic efficiency of the coastal zone affects the land use,spatial organization and city layout of coastal regions.With the application of geographic information system and spatial measure in urban morphology becoming more and more perfect,this paper builds on the GIS platform with Qingdao as the research area to construct the analysis methods and related index of coastal regions land use pattern,spatial external form,internal form,establishes the database.Taking the evolution of Qingdao coastal zone function and the course of urban development as the context,this paper analyzes the characteristics of near-shore land use structure,characteristics of “toward the sea”,development intensity and the difference between the distance from the sea.This paper summarizes the spatial pattern of Qingdao's coastal zone use and coastal regions land use evolutionary characteristics.Secondly,it analyzes the functional characteristics,spatial characteristics and temporal characteristics of the urban spatial expansion of Qingdao,and reveals the process,mode and function of coastal zone evolution of Qingdao urban spatial expansion.Finally,the research scope of the main urban area of Qingdao is selected to analyze the relationship between the spatial distribution of different functional coastal zones and the layout of coastal regions,and summarize the current distribution characteristics of main functional land and the spatial form of coastal regions.The study of coastal regions city morphology has formed a three-level research framework of near-shore land use pattern,urban external form,and urban internal form.
