Type identification and potential evaluation of rural idle residential
renovation: A case study of Yuzhong County, Longzhong Loess Hilly
Region, China
Abstract
The land problem is the key to the implementation of the Rural
Revitalization Strategy, and the land suitability evaluation is the
basis for the renovation and classification of the rural idle
residential. Taking Yuzhong County in the Loess Hilly region of
Longzhong, China as the research area, this study integrated
multi-source data, such as rural residential ownership confirmation
data, survey data of land use, high-resolution remote sensing images,
and field research to construct an idle residential identification
matrix. According to the evaluation results of ecological protection
suitability, agricultural production suitability, and construction and
development suitability, we followed the principle of “ecology first,
agriculture second, after construction and setting,” and realize
renovation zoning of rural residents through the advantage type
identification method. The results show that the waste in rural
residential is serious, and there are significant phenomena of “one
household with two houses” and “one household with multiple houses.”
The renovation potential of 1700 idle rural residentials patches is
117.52 hm 2. In addition, there are significant
spatial differences in the suitability of rural residents in Yuzhong
County. The rational guidance and planning layout of rural residential
renovation can be realized by identifying the type of renovation by the
spatial combination of different land uses in terms of ecological
protection, agricultural production, and construction and development
suitability. This can provide an important decision-making basis for the
rational utilization of rural idle residential and national land-space
planning. Finally, the rural residential renovation should be guided by
the national land space planning. The government should do a good job in
the rural residential renovation planning, formulate a scientific plan
for the renovation, relocation, and reuse of rural “hollow houses.”
Adapting to local conditions, the government should gradually adjust and
optimize the layout of rural residential land, improve the comprehensive
utilization efficiency of rural land, stimulate the vitality of rural
land resources, and promote the rural revitalization and the improvement
of rural living environment.
