Abstract:
Abstract: Research on rural settlements spatial pattern and their evolution helps to reveal the interaction between human and land in different development stages and different areas. It provides theoretical basis for rational land use planning and rural settlement classification management. Rural settlements' morphology reflects both the natural geographical and social economic development condition. According to our research, rural settlements' morphology characteristic has significant correlation with topography, population and living condition of people, etc. Therefore, attributes of rural settlements themselves, namely their displayed morphology, can be used to replace the commonly-used index for the zoning of rural settlements. Meanwhile, spatial autocorrelation method can measure the morphological characteristics of spatial agglomeration pattern which provides the foundation for concentrated continuous rural settlements zoning. Taking Pinggu District, Beijing City as an example, the paper conducted a study on the spatial pattern and zoning of rural settlements. The paper extracted rural settlements in 1993, 2003 and 2011 in Pinggu District. Spatial autocorrelation was applied to depict the spatial pattern of rural settlements morphology characteristics, including the size, shape and distribution. And then the relationship was analyzed between size, shape and distribution characteristics of overlapped regions. On the basis of the spatial autocorrelation result and the overlap region analysis, we put forward the comprehensive management zoning of rural settlements. The main results of the study were as follows: Firstly, size, shape and distribution showed significant spatial autocorrelation. Positive autocorrelation types took the form of the group, whereas negative ones scattered. Secondly, obvious differences existed in agglomeration characters between the plain and the hilly mountainous areas. Rural settlements demonstrated large size, regular shape and concentrated distribution in plain, whereas rural settlements in hilly mountainous region were contrary to those in plain. Thirdly, size, shape and distribution of agglomeration region had a certain space consistency. Positive autocorrelation of these features had an overlap in hilly mountainous region and in plain, and the overlap degree in plain was relatively low compared to that in hilly mountainous region. The spatial pattern of rural settlements showed space consistency mainly because of terrain and landform. Rural settlements in hilly mountainous region embodied high space consistency which contained low-low agglomeration areas of size feature, high-high agglomeration areas of shape feature and high-high agglomeration areas of distribution feature. Rural settlements in plain embodied relatively low space consistency. The main reason for the phenomenon was the urbanization and economic development. Fourthly, zoning in Pinggu District was based on spatial pattern characteristics, regional planning and advices from experts who were familiar with Pinggu District. The rural settlements were mainly divided into 5 parts, namely the industry land expansion zones, pilot farm operation zones, differentiate administrative zones, distinctive village development zones and relocation and regulation village zones. Industry land expansion area in plains should pay attention to enhance land use efficiency and improve the rural settlements' land use integrated benefits. As for rural settlements at the junction of plains and hilly areas, it should manage differently and promote integrated management mode. Agricultural demonstration areas should adjust the structure in order to improve production and living conditions. What's more, the development of tertiary industry should be encouraged in the villages. Moving and merging village areas and distinctive village development zones should realize the integration development and improve the infrastructure construction.
