SDUDY ON SPATIAL DISTRIBUTION AND EVALUATION OF RURAL SETTLEMENT LANDSCAPE IN HUNAN PROVINCE

By studying the spatial distribution characteristics of rural settlement landscape in Hunan province and evaluating it comprehensively,this paper aims to provide reasonable reference for the development of rural tourism in Hunan province.By using GIS10.2 software,the spatial distribution of 147 rural settlements in Hunan province,such as historic and cultural famous villages,towns and characteristic villages with special tourism,was studied.The nearest point index,geographical concentration index and geographical connection rate were calculated to analyze the spatial distribution.The evaluation layer was composed of ecological environment,landscape value,social effect and development conditions,and it was divided into 16 concrete indexes to study the comprehensive evaluation of rural settlement landscape in Hunan province.The result showed that the distribution of the famous village in Hunan province was concentrated and uneven in each city,and the characteristic villages tended to be even and distributed as a whole.In the whole,the distribution of rural settlement landscape and the spatial balance of economic scale in Hunan province had a high degree of coordination.The development of rural tourism based on rural settlement landscape in Hunan province has gradually changed into a sustainable development coordinated by economy and ecological environment,we should take the ecological environment as the starting point,actively excavate the landscape value and produce certain social effects,so as to promote the healthy development of rural tourism.
