Eco-Functional Regionalization Of Tai'an Prefecture, Shandong Provice

Focusing on the concrete analysis of each regionalization of eco-function and the material analysis made by all levels governments of Tai'an City on long-term planning and its own situation of regionalization, the paper establishes ARCGIS as the basic data procession and analysis interface, and unites the land utilization, vegetation, DEM, satellite image and related social economic data. The procession of regionalization concentrates not only on integrity of topographic unit, but also on function relation between upstream and downstream of the basin thereof and development feature of social economics, as a result, the regionalization will be more comprehensive, objective, and practicable.Firstly, the paper evaluates the comparability and discrepancy among the regional present situation, sensitivity of eco-environment, importance of eco-system service function and social development, after which a serial of evaluation paragraph on the same scale is formed. Secondly, the eco-function regionalization is completed superincumbently based on the classification system thereof or combined from bottom to top adopting the method of space superposition, relativity analysis, Brain storm, etc.Through the regionalization of eco-function above mentioned, the paper defines the structure, course and character of space distribution of the type of eco-system in Tai'an City, and forwards the main eco-enviromental problems, reasons, and its space distribution pattern accordingly. At the same time, the paper also evaluates the eco-service function of different eco-systems and its effect on regional social economic development, puts forward its distribution character and high-sensitivity division of regional eco-environment, and proposal of eco-function regionalization, eco-environment of different eco-function areas and its social economics function, direction of development and know-how to management. Finally, the paper has built up a space and geographic frame for Tai'an city on general management of construction of eco-city, optimized setup and rationalization of resources and economics development, and protection of eco-environment, meanwhile, the target of which is foundation of the basic G1S database of eco-function regionalization, proposal on regionalization of Tai'an City, and countermeasures on regional development.
