The Resource Potential and Optimization of Rural Housing Land under Utility Structure Evaluation in Metropolitan Suburbs Villages of China.

Reasonable resource potential calculation is the basic premise for the country to formulate planning and carry out rural housing land consolidation, which can deepen the research on the economical and intensive use of rural construction land. This paper evaluates farmers' area demands of rural housing land by using the consumption utility function, analyzes the spatial pattern characteristics of demand and potential, and puts forward suggestions for the resource optimization of rural housing land based on the survey data of 613 farmers and land use data in the Pinggu District of Beijing in 2005 and 2018. Research shows that the utilities of life, production, and the ecological are carried and measured by the corresponding internal land-use structure of rural housing land. The proportion of life land area was the largest, and the life and production land area decreased from plain to mountain, from 119.76 m² to 89.07 m² and from 44.87 m² to 32.85 m², respectively. The average area potential is 395.64 m² and the change range is −30.35–1413.75 m², which is basically in accordance with the normal distribution. The area potential can be divided into five grades, which are expressed by I, II, III, IV, and V in order of potential from small to large by using the natural fracture method. The utility needed should be enhanced and expanded, and the redundant utility should be removed and socialized in the village. The resource optimization and allocation of rural housing land should be promoted according to the idea of regionalization and classification. It provides scientific support for the reform of rural housing land. [ABSTRACT FROM AUTHOR]
