摘　　要：为给广西森林人家空间分布与可达性优化提供实证参考,以广西2018—2022年认定的81家森林人家为研究对象,采用GIS分析其空间分布特征,采用栅格成本加权距离法对交通网络和地理环境等可能影响可达性的因素进行分析和可视化展示。结果表明,广西森林人家空间分布格局存在不均衡性,但向均匀分布发展;空间分布集聚性增强,总体以各市市区为中心,呈“多点扩展”-“圈层蔓延”-“分散连片”的演变趋势;热点区呈由点状向片状演变的格局,形成桂林市-柳州市-河池市东西贯穿带,其与钦州市、南宁市和贺州市形成连续片状热点区。广西森林人家可达性整体水平不高,受交通网络和地理环境影响较大,交通指向性明显。广西森林人家空间分布和可达性区域差异均较明显,整体空间分布特征与可达性耦合程度较高。In order to provide empirical references for optimizing spatial distribution and accessibility of forest houses in Guangxi,taking 81 certified forest houses in Guangxi from 2018 to 2022 as research objects,GIS was used to analyze spatial distribution characteristics,and raster cost-weighted distance method was used to analyze and visualize factors influencing accessibility,such as transportation network and geographical environment.Results showed that spatial distribution pattern of forest houses in Guangxi exhibited unbalance,but showed trend toward uniformity.Aggregation intensity of spatial distribution enhanced,and showed evolution trend of"multi-point expansion"-"circle spread"-"scattered contiguous patch"with centers of various cities as centers.Hot spot zones showed evolution pattern from point to patch,forming east-west corridor(Guilin-Liuzhou-Hechi),which with Qinzhou,Nanning and Hezhou formed contiguous hot spot zone.Accessibility of forest houses in Guangxi remained relatively low overall,significantly affected by transportation network and geographical environment,with obvious transportation directivity.Spatial distribution and accessibility of forest houses in Guangxi had obvious regional differences,and overall spatial distribution characteristics showed strong correlations with accessibility.
