【摘要】：农村建设历来是我国关注的重点。长沙市作为一个典型山地-丘陵地区的城市,特别是2005年以来长株潭一体化区域规划建设的提出促使区域农村经济社会的转型,导致乡村聚落空间变化的加快以及各类型之间差别的扩大。因此,研究该区域乡村聚落的形态特征,划分不同地域类型,对于研究长沙市乡村聚落的经济发展和社会转型以及长株潭一体化后的长沙市新农村分类建设提供研究指导与调控依据。本论文以2013年长沙市的遥感影像数据为基础,采用GIS探索性空间分析和景观空间韵律测算方法,分析了长沙市乡村聚落的形态特征,并划分长沙市121个乡镇的地域类型。结果表明：在空间上,长沙市乡村聚落集聚程度具有一定差异性,总体表现为由中、西两部地区向东部递减式分布。在规模上,长沙市乡村聚落的数量多,聚落规模较小且相互间差距不大；规模分布上呈现高值集聚分布的特征以及高低集聚值相互间隔结构的特征。在形态格局上,对五条样带指标进行测算,发现长沙中部地区的聚落复杂程度高于西部和东部,北部总体低于南部；长沙东部和北部的乡村聚落连接稳定性优于其他地区；长沙东部和南部的乡村聚落的差异性变化大；长沙中部和北部的乡村聚落破碎化程度较高。通过构建乡村聚落的形态指标体系,选取6种指标,运用spss20.0中主成分分析和系统聚类分析法,将长沙市各乡镇分为7种地域类型。最后,根据长沙市乡村聚落空间分布特征和类型划分情况,划分三个不同的密度区域,提出长沙市乡村聚落合理调整的建议。
[Abstract]:Rural construction has always been the focus of our attention. Changsha, as a typical mountainous and hilly city, especially since 2005, the development of integrated regional planning and construction of Changsha, Zhuzhou and Xiangtan has promoted the transformation of regional rural economy and society. It leads to the acceleration of rural settlement spatial change and the expansion of the differences between different types. Therefore, the study of the morphological characteristics of rural settlements in this region, divided into different regional types, It provides guidance and regulation basis for the study of the economic development and social transformation of rural settlements in Changsha and the classification and construction of new rural areas in Changsha after the integration of Changsha, Zhuzhou and Xiangtan. Based on the remote sensing image data of Changsha in 2013, this paper analyzes the morphological characteristics of rural settlements in Changsha by using GIS exploratory spatial analysis and landscape spatial prosodic measurement method, and divides the regional types of 121 villages and towns in Changsha. The results show that there is a certain difference in the agglomeration degree of rural settlements in Changsha, and the distribution of rural settlements in Changsha is decreasing from the central and western regions to the east. In terms of scale, the number of rural settlements in Changsha is large, the scale of settlements is small and the gap between them is small; the distribution of scale shows the characteristics of high value agglomeration distribution and the characteristics of high and low agglomeration value interval structure. On the aspect of morphological pattern, it is found that the complex degree of settlement in the central part of Changsha is higher than that in the west and east, and in the north is lower than that in the south, and the stability of the rural settlement in the east and north of Changsha is better than that in the other regions. The rural settlements in the east and south of Changsha vary greatly, and the rural settlements in the middle and north of Changsha have a higher degree of fragmentation. Through constructing the form index system of village settlement, selecting 6 kinds of indexes, using principal component analysis and systematic cluster analysis in spss20.0, the towns and villages in Changsha are divided into 7 regional types. Finally, according to the spatial distribution characteristics and types of rural settlements in Changsha, three different density areas are divided, and suggestions for rational adjustment of rural settlements in Changsha are put forward.
