| The rural settlements are living and production space units for rural population, which are the complex that is constituted by houses, roads, vegetation, and some public facilities together, and which are comprehensive product in a particular geographical environment and socio-economic background interactions between human activities and natural conditions, whose change are effected and restricted by natural, socio-economic, policy and institutional. For similar natural conditions of the region, socio-economic conditions and policy are main reasons for rural settlements change. Therefore, there are many difference in change regular pattern and driving mechanism between different economic conditions region. At present, lack of related research,strengthening the research of rural settlements land use temporal evolution under different economic conditions help to understand the change regular pattern of rural settlements. And there are important significance for rural settlements to scale control, layout optimization and new rural construction.In this paper, the study area is two typical county in Henan Province,which is agricultural county(Shenqiu county) and industrial county(Xiangcheng city). This paper analyze and contrast the evolution characteristics of rural settlements by using spatial analysis indicators, in space-time evolution of rural settlements in 2000-2013 for the study, based on a comparative analysis of changes in the data and the main line of GIS spatial analysis techniques.Because the natural conditions are basically the same for two counties, so this paper mainly have qualitative and quantitative aspects of description, from the social and economic conditions of the driving force,and analyse in-depth different types of drive mechanisms socioeconomic county settlements. Its findings as follows:(1)the scale of rural residential in agricultural county(Shenqiu county) and industrial county have different characteristics and variation in temporal evolution. From per capita level of rural residential land, they are similar, but for the increase, the rural residential average land in Xiangcheng was significantly greater than Shenqiu County.Agricultural county and industry county are different in degree of change in rural settlements.By comparing two typical county in whole, we found that variation and change range are almost the same magnitude, but there is a large difference in the change of the township in the period. The variation and change range in township of Xiangcheng City are uniform and insignificant, butchange range is very large for some townships and is small for most townships in Shenqiu.The rate of change of rural residential of industrial county and agricultural county as a whole is insignificant, but they are quite different in terms of the township.The rural residential overall size in agricultural county is less than the size of the industrial county,but the pace of change is consistent.(2) In the driving force, combining the characteristics of spatial layout changes of rural settlements in Shenqiu county and Xiangcheng city,the paper analyse qualitatively that economic driving forces can be attributed to demographic factors, economic factors, urbanization and industrialization, transport factors and radiation from area towns factors towns and so on. From the correlation analysis,we can obtain the results: Overall, there is a high correlation in each driving force factor of the rural residential in Shenqiu.The overall correlation in each driving force factor of rural settlements in Xiangcheng city is less than Shenqiu county, including some small factor in correlation.From the results of principal component analyse,we can obtain: the similarity on the driving force of evolution of rural settlements is included economic development in Xiangcheng city and Shenqiu county, is mainly reflected in the increases of GDP, fixed asset investment, and the second and third industrial production, agriculture, forestry, animal husbandry and fishery output and so on.The difference is that rural residential development of Shenqiu which is a typical agriculture county mainly depends on the improvement of living standards of farmers and the increase arable land,while the driving force of xiangcheng is mainly from industrial structure change and development of urban and rural integration as a typical industrial county. |
