【摘要】：以遥感图像分类解译数据为基础,利用核密度、道路交通可达性阻力值、Logistic回归模型,定量识别了1990-2013年的广东省全域范围内的乡村聚落空间分布特征及现状、乡村聚落空间分布的主导影响因素,并讨论归纳了乡村聚落演变及其机制研究的内容框架。结果表明:(1)广东省乡村聚落空间分布具有低海拔、低坡度、邻河流、邻乡镇的空间指向性。呈现出"平原稠密,山区稀疏"的空间分布格局,形成了粤东潮汕平原和粤西湛江平原台地两大高密度核心区域,珠江三角洲外围山区的乡村聚落呈现出邻近于河流谷地和沿交通线串珠式布局特征。(2)乡村聚落除具有邻近开放型道路空间指向性外,更为重要体现为到乡镇的道路交通可达性对乡村聚落空间分布影响最大,镇—村连接的交通网络完善度对乡村转型发展的意义重大,全面提升乡镇的综合生产和服务能力将是优化农村地区村镇体系的核心。(3)高程和坡度是影响乡村聚落的分布、规模、形态的两个重要的基础性影响因素。自然地理本底属性是村庄优化布局与空间重构规划建设考虑的第一要素。(4)在"互联网+"时代背景下,重构农村地区市场网络体系对接于全球市场网络体系,建构以乡镇为核心的乡村生活服务圈,有待进一步探寻"三生空间"的重构和社会文化传承与保护的理论与实践的研究。同时深化乡村聚落形态演化、乡村空间生产、乡村社会网络、群体行为、社会自治、社会文化领域等的研究将是全球化背景下中国乡村空间重构研究的核心领域。
[Abstract]:Based on the classification and interpretation data of remote sensing images, using nuclear density, road traffic reachability resistance value and Logistic regression model, the spatial distribution characteristics and present situation of rural settlements in Guangdong Province from 1990 to 2013 were quantitatively identified. The main factors affecting the spatial distribution of rural settlements are discussed and the content framework of the study on the evolution and mechanism of rural settlements is discussed. The results are as follows: (1) the spatial distribution of rural settlements in Guangdong Province has the characteristics of low elevation, low slope, spatial directivity of adjacent rivers and towns. The spatial distribution pattern of "dense plain and sparse mountainous area" formed two high density core areas of the Chaoshan Plain and Zhanjiang Plain in the east of Guangdong Province and Zhanjiang Plain in the western part of Guangdong Province. The rural settlements in the peripheral mountainous areas of the Pearl River Delta show a series of beaded distribution features adjacent to the river valley and along the traffic lines. (2) the rural settlements have the spatial directivity of adjacent open roads. More importantly, the road traffic accessibility to villages and towns has the greatest impact on the spatial distribution of rural settlements, and the degree of perfection of the traffic network connecting towns and villages is of great significance to the rural transformation and development. To improve the comprehensive production and service capacity of villages and towns in an all-round way will be the core of optimizing the system of villages and towns in rural areas. (3) elevation and slope are two important basic factors affecting the distribution, scale and form of rural settlements. The background attribute of physical geography is the first factor to be considered in the planning and construction of village optimal layout and spatial reconstruction. (4) under the background of the "Internet" era, the reconstruction of the rural market network system is connected to the global market network system. The construction of rural life service circle with township as the core needs to further explore the reconstruction of the "three living spaces" and the theoretical and practical research on the inheritance and protection of social culture. At the same time, the research on the evolution of rural settlements, rural space production, rural social network, group behavior, social autonomy, social culture and so on will be the core areas of the study of rural space reconstruction in China under the background of globalization.
