| At present,China has entered the stage of stock-based development,and the renewal of old urban communities has entered a period of comprehensive promotion.In 1980’ s,as an old community,residential areas showed signs of decline more or less due to the lagging development of property management.However,as a product of a specific historical period during the transition period from planned economy to market economy,It still has unique value in the aspects of form layout,planning method and community neighborhood.At present,the case-by-case updating method based on project menu in old residential areas can deal with the quality of life problems that need to be solved urgently,but it can’t show the value and characteristics of residential areas in 1980 s from the perspective of urban system,so it is urgent to provide method support by planning research.Firstly,this paper sorts out the data information such as local sentiment books and planning materials since the reform and opening up of Nanjing,and obtains the distribution and development evolution process of residential areas in Nanjing in 1980s;On the basis of this,field investigation is conducted to identify,classify and count the details and attribute characteristics.Summarize the generation mechanism,construction and distribution,evolution mechanism after completion,and current attribute characteristics of residential space,and then form a deep understanding of its morphological characteristics.Then,according to the morphological characteristics and evolution complexity of residential areas in Nanjing in 1980 s,the morphological expression method suitable for residential areas in Nanjing in 1980 s was constructed by using morphological theory and research methods,including the morphological evolution and generation mechanism of "residential areas and urban pattern,road space,plot function,buildings and public spaces in plot".As well as the analysis and research on the plane pattern hierarchical structure of "block plot-functional plot-functional plot-management plot".Based on the spatial syntax theory,the framework of residential area plane-transportation system is modeled and analyzed,and the correlation between spatial form and residents’ activities is obtained.Finally,taking the Nanhu residential area in Mochou Lake Jiedao of Nanjing as a research case,this paper makes an in-depth investigation of the residential area,and analyzes and explores the plane pattern and generation mechanism of the residential area by using the constructed form expression method.Associate residential form with livability,evaluate livability,sum up the value and existing problems of residential form,and put forward new guiding strategies.To provide the basis for the renewal design in space form for the subsequent renewal of residential areas.This paper studies the residential areas in 1980 s from the perspective of morphological typology,which enriches the research content of residential areas and expands the new perspective of residential renewal research.In addition,this paper also analyzes and sorts out the form types and value characteristics of residential areas in Nanjing in the 1980 s,and explores a set of form analysis and evaluation methods suitable for residential areas in the 1980 s to present the value characteristics and problems of residential areas.At the same time,it also provides reference for the renewal and development of residential areas in Nanjing in 1980 s. |
