Abstract: |
After China entered the stage of rapid urbanization, urban development has become
faster and faster while rural areas have declined. The contradiction between urban and rural dual
structure has deepened. This dual structure would be solved by balancing the allocation of urban
and rural resources and promoting the integrated development of urban and rural areas. The
counties are the most appropriate geographical space to accelerate urban-rural integration. The
scientific and reasonable county settlement systems are significant to the development of the new-
typed urbanization and rural revitalization in China. Studying the spatial evolution law of county
settlements has important academic value and practical significance for the optimization of the
county settlements system. There are more mature empirical studies at the city scale and less studies
at the county scale. Compared with inland areas, economic activities and social development are
more active in coastal areas. With the rapid industrialization and urbanization, the rural system
of coastal areas has changed dramatically, resulting in the reconstruction of rural settlement. At
the same time, affected by the regional conditions, economic development, policies and other
factors, the urban and rural boundaries of coastal counties are weakened. Coastal areas are not only
important carriers of economic development, but also hot spots of population mobility. In particular,
the counties in the eastern coastal areas are important research nodes in the transformation from
rural areas to urban areas. For example, the coastal areas in Zhejiang Province, relying on superior
ecological resources, have witnessed the rapid development of modern aquaculture and rural leisure
tourism industries, the transformation of traditional agriculture, and continuous decline of traditional
agricultural settlement space. Therefore, the study of the evolution process and agglomeration
characteristics of county settlements in coastal non-traditional agricultural areas is helpful to
understand the urban-rural integration development at the county level.
Taking Ninghai County, Zhejiang Province, as an example, this study analyzed the spatial
evolution characteristics of settlements in Ninghai County, Zhejiang Province, from 1990 to 2020,
using the central place theory, the rank-size rule, fractal dimension and other theoretical methods.
The results showed that the spatial evolution law of the coastal non-traditional farming areas tends
to be like the law of the urban areas, but there was still a gap between them due to the limitation of
county population and economic development. The settlement in Ninghai County clustered along
the central axis with high cores and the relatively stable multi-center network hierarchy has formed.
During this period, the settlements of Ninghai County expanded outward through four evolutionary
ways.
As a non-traditional agricultural area, Ninghai County was influenced by agricultural
modernization and the development of rural leisure tourism. There was less surplus agricultural
labor force in the county, and the labor force distribution was unbalanced. The spatial differences
of population and labor force directly affected the evolution of the spatial distribution of county
settlements. Industrialization and agricultural modernization leaded to the transformation of rural
functions. The farmers’ lifestyle and living locations have changed accompanied by the rapidvariation of economic structure and employment structure. With the transformation of rural functions and the acceleration of population mobility, the size
of agriculturally based settlements gradually decreased, and some small-scale rural settlements even disappeared. The rural settlements, which aimed at
agricultural modernization, characteristics agriculture, eco-tourism and industry, have gradually formed and expanded. These elements of modernization
would certainly affect the temporal and spatial evolution of county settlements, forming an evolution law different from the historical evolution trend. In
terms of the spatial evolution of county settlements, coastal non-traditional agricultural areas were quite different from traditional agricultural areas, owing
to the impact of their different industrial structure, location conditions, policy supports, etc.
The contribution of this paper was to explore the evolution law of the spatial distribution of county settlements in coastal non-traditional rural areas,
and analyze the hierarchical system of settlements, which was of great significance and practical value for the optimization of the county settlements system
and the integration of urban and rural development. |
