【摘要】：在特别强调“城乡统筹发展”和“新农村建设”的今天,研究乡村聚落空间模式具有重要的理论与实践意义。本论文以云南迪庆藏族自治州乡村聚落的空间模式为研究对象,从卫星遥感图像和DEM高程数据作为主要数据源,并通过核密度制图、缓冲区分析、空间叠加分析等地理信息技术方法,从宏观层面上提取和分析了迪庆州乡村聚落的空间集聚模式和空间分布类型模式,从中观层面对乡村聚落的空间形态模式、空间布局模式以及传统街巷空间结构模式进行提取与解析。通过研究得知,迪庆州乡村聚落在空间上呈高度集聚特征,具体表现为具有明显的带状集聚分布特征,有突出的地区差异分布特征,并且,整体上来看,研究区聚落分布存在两个明显的集聚核心。迪庆州乡村聚落体现出三种独具特色的空间集聚模式,即“多线轴、近平行带状模式”、“梳状结构模式”和“高寒无人模式”。通过将迪庆州乡村聚落分布图层和地形、河流、道路图层叠置分析,得知乡村聚落空间集聚特征与集聚模式的形成,是地形、河流、道路等多种因素综合影响的结果。根据聚落边界闭合图形的形态特征,迪庆州乡村聚落的形态模式可分为五种,即:团状模式、组团模式、指状模式、带状模式和散点模式。其中,迪庆州聚落空间形态的主导模式是散点模式。独特的地形地貌条件,形成了迪庆州多样化的乡村聚落布局模式。主要布局模式有:依山就势模式、依坡建村模式、支流入江口模式、平行等高线的台阶式模式、垂直等高线模式、沿山脚边缘的模式、沿河模式、沿道路模式和地形纹理契合模式。线型、树枝型、网络型是迪庆州最为普遍的街巷空间结构模式。
[Abstract]:In this paper, the spatial model of rural settlements in Diqing Tibetan Autonomous Prefecture of Yunnan Province is taken as the research object. The satellite remote sensing images and DEM elevation data are used as the main data sources, and the buffer zone is analyzed by nuclear density mapping. The spatial agglomeration pattern and spatial distribution pattern of rural settlements in Diqing state are extracted and analyzed from the macro level, and the spatial patterns of rural settlements are analyzed from the view of the middle level, such as spatial superposition analysis and other geographic information technology methods. The spatial layout pattern and the traditional street and lane spatial structure model are extracted and analyzed. Through the study, we know that the rural settlements in Diqingzhou have a high agglomeration feature in space, which is manifested by obvious zonal agglomeration distribution characteristics, prominent regional difference distribution characteristics, and, overall, There are two obvious agglomeration cores in the study area. There are three unique spatial agglomeration modes in the rural settlements of Diqing Zhou, namely, "multi-axis, near parallel banded pattern", "comb-like structure mode" and "alpine uninhabited mode". Based on the stratification analysis of the distribution layer, river and road map of rural settlements in Diqing state, it is concluded that the formation of spatial agglomeration characteristics and patterns of rural settlements is the result of the comprehensive influence of many factors, such as topography, river, road, and so on. According to the morphological characteristics of the closed pattern of the settlement boundary, there are five kinds of morphological patterns of the rural settlements in Diqing state, that is, the cluster model, the group pattern, the finger pattern, the band pattern and the scattered point model. Among them, the dominant pattern of the spatial form of Diqing state settlement is the scattered mode. The unique terrain and landform conditions form the diversified rural settlement layout model of Diqing Prefecture. The main layout patterns are as follows: the model of building villages according to the mountain, the model of building villages according to the slope, the model of branch flowing into the estuary, the class model of parallel contours, the model of vertical contour, the model along the edge of the hill, the model along the river, Along the road pattern and terrain texture fit mode.
