摘要
民族聚落的发展,受自然地理、历史文化、时代进程等因素的综合影响。基于核密度估计和空间自相关性分析,选取怒江州独龙江乡的独龙族聚落,探究其分布特征与形成的影响因素。结果表明:对独龙族聚落进行核密度分析时,搜索半径10 km最为合理,核密度估计值最大为3.92个/km^(2);独龙族聚落核密度分布全局Moran′s I=0.6823,表现为空间集聚的态势,分析局部自相关发现空间分布主要表现为HH集聚型和LL集聚型,HL和LH集聚性极少,HH型集聚集中在中部区域,LL型集聚集中在北部区域;空间计量自回归模型分析显示影响聚落点分布的因素为地形位指数>道路密度>水系密度,地形位指数和道路密度为正相关,水系密度为负相关。证实了独龙族的聚落分布特征是自然地理环境、民族历史文化等多种因素综合作用的结果。
The development of ethnic settlements is comprehensively influenced by geography,history and culture,and the progress of times.Based on kernel density estimation and spatial autocorrelation analysis,this paper selected the Dulong settlement in Dulongjiang Township,Nujiang Prefecture,and explored its distribution characteristics and influencing factors.The results show that when analyzing the kernel density of Dulong settlements,the search radius of 10 km is the most reasonable,and the maximum kernel density estimate of Dulong settlements is 3.92/km^(2);Global Moran′s I=0.6823,which is manifested as a trend of spatial agglomeration.Further analysis of local autocorrelation shows that spatial distribution is mainly manifested as HH and LL clustering,while HL and LH clustering are rare,and HH-type clustering is concentrated in the central region,while LL clustering is concentrated in the northern region;The analysis of spatial econometric autoregressive model shows that the influencing factors on the distribution of settlements are terrain niche index>road density>water density,terrain niche index and road density were positively correlated,while water system density was negatively correlated.The research findings show that the distribution characteristics of ethnic group settlements are the result of the joint action of geographical environment,ethnic culture and other factors.
