The rural construction and development is the foundation of social stability andharmony. However, because of the natural geographical environment, climaticconditions, mode of production and life,religious practices and other efe tors, theformation and development of rural settlements in China have been in a spontaneousstate for a long time. There are problems such as scattered layout, small populationsize, large floor space, low rate of land use and so on. With the rapid development ofsocial economy, it has important practical significance for guiding the development ofrural construction, improving rural living environment, saving land resources tostrengthen the study on distribution characteristics and layout optimization of ruralsettlements space. Therefore,this thesis takes the a^ine pastoral area--ruralsettlement in Luqu County as the research object and analyzes the characteristics ofthe spatial distribution of rural settlements and the conprehensive developmentstrength in Luqu County, by using the spatial analysis functions of the geographicinformation system and combining the second present land-use survey map of LuquCounty and social economic data. Finally,it proposes the optimizing and adjustingmode of spatial layout of rural settlement in Luqu County.(1)A quantitative analysis of the characteristics of spatial layout of ruralsettlement in Luqu County is carried out rfom the aspects of natural factors, such aselevation,slope, river, and climate etc., by using the second present land-use surveymap of Luqu County and the spatial analysis function of ArcGIS. The results showthat, the county rural settlements are mainly distributed in the Taohe River Valley andthe plateau surface with the gentler slope where the altitude is relatively low andtemperature is relatively mild. It takes80%of the account of Luqu County Ruralsettlements.(2)This thesis then qualitatively and quantitatively analyzes the humanistic andsocial efe tors that influence the spatial distribution of rural settlements in LuquCounty. The factors include tribe factors, religious factors, regional economic efctors,traffic factors and policy efctors. The results show that, the tribal system and religiousculture is the essential factors affecting the spatial distribution of rural settlements inLuqu County, but with the development of social economy and the improvement of people’s living standard, the traffic efe tors and national policy have gradually becomeimportant factors affecting the spatial layout of Luqu County settlements.(3)Using the CV value method of the Voro no i diagram, the thesis analyzes thespatial distribution pattern of rural settlements of Luqu county and townships. Theresults show, in the county scale,the CV value of Luqu County is190.21%, and therural settlement is distributed in cluster; in the township (town) scale, Ma’ai Town,Xicang Townsh^, Shuangcha Township, Ala Townsh^, Langmu Temple town andGahai Township are spatially distributed in cluster, while La Renguan Township isdistributed evenly. Nevertheless,through field researches, we discovered that due tothe influence of traditional economic formation of animal husbandry culture, the ruralsettlements in Luqu County spatially scatter in general; and in the local area, it isclustered distribution.(4)This thesis uses evaluation on the comprehensive development strength ofrural settlements and rural spatial interaction analysis as basis,combined thecharacteristics of the spatial layout of Luqu County settlements, divides the layoutoptimization of rural settlements of the whole county into four kinds of patterns, Le.urbanization mode,priority development mode,control mode of development andrelocation mode.
