Abstract:

Based on the decoupling theory, this study analyzed the urban, rural, and urban-rural construction land and population change decoupling status and characteristics in China at the prefectural level. A decoupling-based land-use zoning model was built to explore land conversion and intensive utilization strategy in different land use zones. The results show that: (1) At the national level, the relationship of urban-rural human population and construction land was in an uncoordinated state. During 2010-2016, urban construction land and population both stably increased. However, rural construction land significantly expanded while rural population has been rapidly decreasing at the same time. (2) At the prefectural level, the decoupling types of cities in China varied in different dimensions. Cities whose urban-rural human-land relationships were uncoordinated accounted for 74.2% of all cities in China. Meanwhile, cities with uncoordinated urban human-land relationships accounted for 36.2% of all cities in China. Besides, 81.6% of all cities in China had uncoordinated rural human-land relationships. (3) On the basis of decoupling types, land use were divided into four types, including urban-rural intensive, urban intensive, rural intensive, and urban-rural extensive. Cities in urban intensive and urban-rural extensive zones accounted for 97.9% of all cites in China. According to the characteristics of different land use zones, this study suggested various regulatory and control countermeasures, in order to promote the sustainable development in urban and rural areas.
