基于POI数据的新疆农家乐空间分布特征及影响因素研究

Spatial Distribution and Influencing Factors of Xinjiang Farmhouse Resorts:An Analysis Based on POI Data

基于POI数据,收集新疆3463家农家乐信息,并将其分为经济型农家乐和星级农家乐,运用最邻近指数、变异系数、核密度分析等方法探究各类型农家乐空间分布特征;采用负二项回归模型分析影响各类型农家乐分布的因素.结果表明:①新疆经济型农家乐、星级农家乐以及农家乐总体在空间上均表现为聚集的分布态势,且聚集分布特征的显著性较强;②经济型农家乐和农家乐总体分布相似,北疆农家乐核密度以带状分布和点状分布为主,南疆农家乐核密度仍以点状分布为主,星级农家乐南北疆核密度均为带状分布和点状分布;③各类型农家乐分布均呈现显著的空间正相关,局部看来“低—低”聚集性更为明显;④负二项回归显示,生态环境、交通条件、资源禀赋及旅游业发展水平对各类型农家乐空间布局有着显著影响,自然因素和农业发展水平直接影响农家乐总体分布,而对农家乐质量等级的影响有限,城镇化水平对新疆各类型农家乐布局影响不显著.

This paper explored the spatial distribution characteristics of various types of farmhouse resorts using the nearest neighbor index,coefficient of variation,kernel density,and other spatial analysis tools,based on the samples of 3463 farmhouse resorts collected from POI data in Xinjiang.The negative binomial regression model was used to analyze the factors affecting spatial distribution of farmhouse resorts.The results showed that:(1)The spatial distribution of all types of farmhouse resorts,i.e.the economic,starred,and the overall farmhouse has a significant agglomeration characteristics.(2)Spatial distributions of economic and whole farmhouse resorts are very similarity,which the kernel density of northern Xinjiang is mainly banded and dotted distributions,but only dotted distribution in southern Xinjiang.The distribution of kernel density of star farmhouse resorts in southern and northern Xinjiang are both banded and dotted.(3)The distribution of all types of farmhouse resorts showed a significant positive spatial correlation,with more obvious local“low-low”agglomeration.(4)The negative binomial regression shows that the ecological environment,traffic conditions,resource endowments,and the level of tourism development have a significant impact on the spatial layout of various types of farmhouse resorts.Natural factors and the level of agricultural development directly affect the overall distribution of farmhouse resorts,but have limited impact on the distribution of star farmhouses.The level of urbanization has no significant impact on the layout of farmhouse resorts in Xinjiang.
