Research On The Measurement And Correlation Of Urban Morphology And Function Under The Compact Concept

In the process of rapid urbanization, China's city land are facing four problems ,which are land increased faster than population growth, city land idle,irrational structure of land use and low city land use efficiency . Therefore, in recent years, a number of city planning and construction practice in compact city, specific initiatives include the control of land size, the delineation of the city boundary and city land by the "incremental expansion" to "stock optimization" construction. At the same time, some of the urban planning staff and scholars in our country have a lack of understanding of the concept of compact city, there are still some errors in the construction of compact city. What kind of city is a compact city, there are two major errors: first, the high-density city is a compact city; second, the city is the shape of the more close to the circular city is compact city. In addition, the study of compact city measure is very rich, but there is little research between the form and function relationship of compact city. For the construction of our country metric compact city and explore the relationship between the city form compact and compact function, the capital city of our country as an example, first of all, on 2006, 2010 and 2014 three years the city form of compactness and compactness of function measure comprehensively, on this basis, try to explore the relationship between the city form compact and compact function.This paper is divided into six chapters: the first chapter introduces the research background and significance, research object and research data, research methods and research framework, and defines the related concepts; the second chapter introduces the research progress of city form and city function, research progress and the origin and development of compact city and the basic characteristics of compact city concept of compact city is summarized; the third chapter is the research of compact capital city of our country form, this chapter is based on previous morphological measure of compactness, the measure method is suitable for the purposes of this study, and the remote sensing images as the data source,the capital city of our country form compact measure and the analysis of the temporal and spatial evolution characteristics;the fourth chapter is to study the compact function of China's capital city,the concept of compact city is constructed including 3 level indicators based on 6, two indicators,13 indicators of the city function compact index system, using entropy method to calculate the function of city compactness, and analyzes the compact space evolution characteristics of the capital city of our country; the fifth chapter is the study on the correlation between China's capital city compact form and compact function, this chapter is in based on the previous two chapters, analyzes the relationship between the city form and function of compact and compact city form and function of each compact level indicators, finally combined with the specific cases of the city, analyzes the construction of our compact city; the sixth chapter summarizes the main conclusions, innovation and shortcomings and puts forward the prospect further research.
