Research On Regional Differences Of Rural Settlement And Influencing Factors In YIYANG

As one of the most important research content in the fields of rural settlement geography, rural settlement is closely associated with agricultural production and have a certain amount of population, are concentrated in certain geographical area, by the natural environment, economic environment, institutional environment, social and cultural environment influence the formation of a certain shape, size, structure and function villages, towns and other rural settlements in general. Rural settlements with the production, development, maturity, decline, rebirth and other complex dynamic features and spatial characteristics. Generation in rural areas inhabited by the development of a historical, geographical, political, economic, cultural, ethnic, religious, scientific, technological, policy, lifestyle, physical awareness, and a variety of factors influence the dynamic process, in different countries, different regions and different development phase of the rural settlements exist in difference space. China's vast territory and natural environment, production characteristics, living habits, geographical and cultural factors, the rural settlements of regional differentiation with complex phenomena to new socio-economic policy situation. Yiyang in the central region is an important commodity grain product on base in Hunan Province, Dongting Lake and the comprehensive utilization of agricultural demonstration zone landforms and diverse city in the mountains, hills, post, flat, lake, taste and high terrain northeast southwest low, and rural lived significantly different, typical in the Central Region of China, with research value. In this paper, the background of the new rural construction,From geography, sociology and ecology perspective,using GIS spatial analysis methods, the introduction of patch number (NP), plaque area (CA), the average plaque area (MPS), patch density (PD), plaque area percentage of landscape (PLAND), largest patch index (LPI), landscape fragmentation index (FN), mean patch shape index (MSI) Landscape pattern analysis of eight indices, Landscape analysis software Fragstats, the spatial distribution of rural settlements in Yiyang, the size characteristics and shape of different features of the external landscape. At the same time the economic structure of rural settlements, organizational structure, spatial structure and agricultural production, farmers living, rural, village capacity in terms of qualitative and quantitative, in-depth study of rural settlements in Yiyang the difference characteristics of the structure and quality. On the basis of characteristics, from the natural environment, regional economic, social and cultural factors should be set fully combed topography, hydrology, land resource conditions, ecological security, economic position, level of economic development, ethnic etiquette, history culture, geomancy, immigration distribution of rural settlements in Yiyang, the formation of regional differences in the impact, has been found in Yiyang City, graduated from the southwest to the northeast lower terrain features in three regions of different hydrological conditions, land resources, natural factors on the impact of Yiyang City, the most protruding rural settlements, rural settlements have made Yiyang City in southwestern mountain region-the central hilly area-northeast of Lake Region's regional differences.
