山地丘陵区城乡交错带土地利用功能评价与分区调控
Functional evaluation and zoning regulation of land use in urban-rural fringe of mountainous and hilly regions
摘要
Abstract
In order to clarify the main contradictions of the more complex human-land relations in the urban-rural fringe,and to seek appropriate strategies to regulate the contradictions.This paper takes Chongqing City,a mountainous and hilly area,as the research object,follows the research logic of"spatial identification-functional evaluation-type classification-zoning regulation",and utilizes ISO clustering unsupervised classification and K-means algorithm to conduct research on urban-rural fringes in Chongqing.The results showed that the total size of urban-rural fringes was 2 378.18 km2,accounting for nearly 80%in the main city metropolitan area with a high degree of urbanization,and only about 20%in the Three Gorges reservoir area in northeastern Chongqing and the Wuling Mountain area in southeastern Chongqing,where the degree of urbanization was relatively low.Due to the restriction of mountainous terrain or the influence of water segmentation,the urban-rural fringes were mostly"block-filled"in the central urban area,and"unevenly ringed"in the rest of the area.The land-use functions of urban-rural fringes in different types of districts were more heterogeneous.Influenced by the topography and the level of urban development,the urban development function of the central urban area of the main city metropolitan area was more prominent,and the rural production function of the main urban new area was more prominent,and the ecological conservation function was stronger in northeastern and southeastern Chongqing due to the constraints of topography and geomorphology.Based on the evaluation results and the national territory development orientation,the urban-rural fringe could be divided into three types of zones:urban development integration,agricultural development dominant,and ecological conservation and protection.The adoption of differentiated land comprehensive consolidation regulation strategies by zones provided engineering paths for the realization of the dominant functions of land use in different types of urban-rural fringes.The results of the study can provide references for land space planning and utilization,management and regulation,and effective governance in urban-rural fringe in mountainous and hilly regions.关键词
