    摘要:

    随着社会发展与生活水平的提高,休闲已经成为人们日常生活中重要的组成部分。以乌鲁木齐市为研究区,依据定义的休闲类POI数据,通过核密度分析技术、最近邻指数等衡量研究区休闲类地理实体的空间分布特征以及关联情况。结果表明:休闲类POI整体呈现集聚的状态,生活休息类POI的集聚效应最强,观光休闲类POI的集聚效应最弱,相对比较分散;各类POI的NNI指数与其数量没有直接的联系,造成其NNI值过小的主要原因是POI集中分布在城市中心区域;依据核密度指数,休闲类POI呈现一种“大中心多分散”的分布格局;生活服务类POI的分布特征最接近整体,观光休闲类POI的空间分布呈现一种“多中心”的态势。

    Abstract:

    With the development of society and the improvement of living standards, leisure has become an important part of people's daily life. This article takes Urumqi as the research area, according to the definition of leisure POI data, The spatial distribution characteristics and correlations of leisure-type geographic entities in the study area are measured by nuclear density analysis techniques and nearest neighbor indices. The results show that the leisure POI is in a state of agglomeration, and the agglomeration effect of the living rest POI is the strongest. The clustering effect of POI in tourism and leisure is the weakest and relatively scattered; the NNI index of various POIs is not directly related to its quantity, The main reason for the small NNI value is that the POI is concentrated in the central area of the city; According to the nuclear density index, the leisure POI presents a “large center and multi-dispersion” distribution pattern; The distribution characteristics of life service POI are closest to the whole, The spatial distribution of tourism and leisure POI presents a “multi-center” situation.
