广州市乡村发展类型及演化模式

Evolution Characteristics and Model of Rural Settlements in Guangzhou City

采用广州市域范围内行政村2005,2013年人口、社会经济、空间等现状摸查数据,运用GIS,SPSS等分析手段,对比研究乡村发展类型、空间特征及其动态演变规律,归纳其演变动力机制。结果表明:(1)影响乡村分类的主因子具有可持续性,但其影响程度总体减弱,而非持续性因子则具有时代特征,影响乡村发展的因子多元化;(2)乡村类型演变呈现由低等级分异向着高等级分异的演变趋势;(3)广州市乡村发展的空间分布整体呈现"圈层状"的分布状态,随着城市副中心的建设,人口、产业、基础设施出现了大幅扩散,乡村发展逐步走向多中心协同发展的局面;(4)广州市乡村发展演化的模式主要有渐变模式、突变模式和惰性模式。

Taking the megacity Guangzhou as an example,this thesis formulates the methodology for analyzing dynamic characteristics of rural agglomerations in metropolitan area through building an evolutionary model of rural agglomeration space at the middle and final stages of metropolitan area urbanization,as well as the in-depth observation of the spatial evolution dynamical mechanism. Through collecting data related to demographic,economic and land attributes of all the administrative villages in Guangzhou,a territory-wide database was established for analysis by means of software tools such as GIS and SPSS,from which results supporting the research objectives can be concluded for the Guangzhou＇s rural agglomerations. Results show that,（ 1） Comparing 2005 with 2013,the influence factors on the evolution of the rural settlements of Guangzhou is more diversified with sustainability and decreasing impacts,while the non-sustainable factor shows the characteristics of era.（ 2） On the evolvement features of the rural settlement type,presenting from low grade differentiation toward the evolvement of the high differentiation trend.（ 3） Spatial pattern of rural settlements in Guangzhou exhibits a typical layer structure at the city level,it is obvious along with the influence of planning and urban development and other factors. There has been a large proliferation of population,industry and infrastructure. The development of villages is gradually moving towards multi center coordinated development.（ 4） On the rural settlement evolvement model,it can be divided into the gradient pattern,mutation pattern and inert pattern according to the stage in the evolution of the rural settlements.
