| The name settlement reflects how people choose and adapt themselves be use d tothe natural and human environment of a place.Different types of land cultures ge state different economic models and showdifferent homestead relationships,which h as different influences on settlementpattern.With the human increasing awareness of the environment,It's very important to research the interaction between settlements and environmental factors.It can be to better facilitate the coordinator of the relationship,and promote the sustainable development of social economy.In this study,through to learn the other scholars about the settlement study,and to use Arcgis,Envi,Fragstats,SPSS and other related software,combine with the knowledge of mathematical methods,physical geography,human geography,economic geography,surveying and mapping to discuss the space distribution of settlement in Xing Yun Lake.The main research methods are spatial analysis,ESDA analysis,landscape spatial analysis and multi-scale analysis.The research results are as follows:(1)Different geographical environment and economic environment is the main influence factors in spatial distribution of the settlement,the whole settlement distribution appears around the Xing Yun Lake and exhibit a convergent,the overall distribution of the settlement showed that the population amounts balanced,the terrain scatter simple,traffic planning convenient and the water richness in dam.(2)The factors of agricultural land distribution,population density,per capita income and social economic status have a great effect on spatial distribution of the settlement.When the agricultural land expressed high-density,the settlement will be formed intensive villages,in the opposite will be formed large density settlements,the population in central area of Jiang Chuan is more dense and the quantity will be spread out of periphery,At the same time,there is a positive correlation between the population and per capita net income,so the population density and per capita income are also the important driving force of the change.(3)The distribution of rural settlements shows equilibrium and agglomeration,the research express that high village density in the south and low village density in the north and will be reduce as area outward.Dajie town and Jiangcheng town is the center of settlements.The spatial distribution of rural settlements in the study area has obvious spatial dependence.(4)The evolution of settlements in Jiang Chuan County,the whole landscape show alternation of stability and expansion,and experienced by the unstable form to stable form.Settlement patches has experienced the process of diffusion type growth to cohesive agglomeration growth.(5)This paper discusses settlement meanings of multi-scale analysis which combined with landscape ecology found that:The surface cover types in Jiang Chuan start to change in the 1995-2000 years,but the change is relatively mild;The surface cover types changed greatly in 2000-2005 years,especially the construction of land and other types of natural landscape,in this period,the waters area also produced changes;2005-2010 years still continue this development mode,as village scale expansion,nature damaged more violent;In the year of 2010-2015,the state of development has entered a gentle stage,the types of land use area is growing to sustainable planning.(6)The spatial distribution pattern of Jiang Chuan is summed up as the development state of "confluence to poly core to progressive".The settlement spatial distribution was mainly dependent on rivers,highways,and plain terrain,showing the pattern of confluence,with the centre town development,the larger rural settlements began to play a central role,and scattered distribution settlements start to move to near centre settlement and form settlement group.With huge economic gap between the developments of town makes the settlement gradually transfer to the economically developed regions,and the migration process is becoming more and more obvious. |
