Abstract:
Because?of?the?natural?geographical?environment,?climatic?conditions,?mode?of
production?and?life,?religious?practices?and?other?factors,?the?formation?and?development?of
rural settlements in China have been in a spontaneous state for a long time. There are problems
such?as?scattered?layout,?small?population?size,?large?fl ?oor?space,?low?rate?of?land?use?and?so
on.This thesis then qualitatively and quantitatively analyzes the humanistic and social factors
that?infl ?uence?the?spatial?distribution?of?rural?settlements?in?Luqu?County.?The?factors?include
elevation,?river,road?network?and?regional?economic?factors.?The?results?show?that,?Altitude?is
affecting the spatial distribution of rural settlements;River and road network on the settlements
has?obvious?guiding?role,from?agricultural?areas?to?semi-agricultural?andsemi-pastoral,?to?pure
pastoral?areas,?Distribution?pattern?of?settlements?transform?from?dispersed?to?centralized?.
Application?of?comprehensive?development?strength?index?function,?Luqu`s?administrative
villages divided into high (Ⅰ),?medium?(Ⅱ),?low?(Ⅲ) three development levels; Introducing
Cost?Weighted?Distance?and?improved?Field?Model?to?calculate?the?radiation?of?townships,
the?results?showed?that?Ma`ai?and?Langmusi?town?have?the?strongest?radiation,?and?Tao?River
