摘要
乡村振兴战略实施的新时代背景下,欠发达地区的乡村聚落空间发展值得关注.文章基于2000年遥感数据、武江区2010年及2016年土地利用变更数据,运用空间韵律指数、土地利用转移矩阵、平均最邻近指数、核密度分析等方法,从空间规模、空间形态和空间分布3个方面,分析了韶关市武江区乡村聚落时空演变特征及影响因素.结果表明:①2000-2016年期间,在空间规模上,武江区乡村聚落的用地规模扩张明显,与林地、耕地、城镇用地之间发生较大面积用地流转,乡村新增斑块主要来源于林地、耕地,转出的去向主要为城镇用地;②在空间形态上,乡村聚落斑块形态趋于规则,城镇周边的乡村聚落形状不规则程度较大,且程度有所加剧;③在空间分布上,乡村聚落保持集聚分布模式,核密度高值总体不变,局部有向城镇、河谷地区加强的倾向.乡村聚落的空间演变受到地形、河流、交通、城镇化与政策等因素的综合影响.文章对推进粤北地区实施乡村振兴战略、促进乡村可持续发展具有一定的参考意义.
In the new era of village revitalization strategy,the development of rural settlement space in underdeveloped areas deserves attention.Based on 2000 remote sensing data,Wujiang District 2010 and 2016 land use change data,using space rhythm index,land use transfer matrix,average nearest neighbor index,kernel density analysis method,the temporal and spatial evolution characteristics and influencing factors of village settlement in Shaoguan Wujiang District were analyzed from three aspects of space scale,space form and space distribution.The results show that:①During the period of 2000-2016,the land scale of rural settlements in Wujiang District expanded significantly,and there was a large area of land transfer between rural settlements and woodland,cultivated land,urban land.The new patches in rural areas mainly came from woodland and cultivated land,and the main direction of the transfer was urban land;②In the space form,the pattern of rural settlement patches tends to rule,and the irregular degree of the rural settlements around the town is more irregular,and the degree of irregular is enhanced;③In the spatial distribution,the rural settlements keep the agglomeration distribution pattern in the spatial distribution.The high value of nuclear density of rural settlements remains unchanged as a whole,and some of them tend to transfer to towns and valleys and plains.The spatial evolution of rural settlement is influenced by the factors such as topography,river,traffic,urbanization and policy.This paper has a certain reference significance to promote the implementation of village revitalization strategy and promote the sustainable development of rural areas in northern Guangdong.
