摘要
用于分析空间数据和空间统计的统计学方法。本研究的案例研究是2016-2018年东加里曼丹按摄政/城市划分的热点平均数量。本研究旨在分析热点数量数据中是否存在空间自相关,确定热点分布格局,并确定2016-2018年东加里曼丹省各县/市森林和土地火灾潜在区域的脆弱性水平。从全局角度分析空间自相关性并确定其分布格局的方法是Moran指数。局部空间自相关指示器(Local Indicator of Spatial Autocorrelation, LISA)用于局部分析空间自相关。采用α = 25%的Moran指数进行全球空间自相关分析结果表明,2016-2018年东加里曼丹地区热点平均数量存在空间自相关。东加里曼丹热点分布格局为传播格局,2016-2018年热点分布于东加里曼丹各区/市。同时,利用LISA的局部分析结果表明,东加里曼丹的几个区/市存在空间自相关性。用于确定潜在森林和土地火灾脆弱性等级的方法是灵活形空间扫描统计和LISA。结果表明,被列入森林和土地火灾危险类别的县/市为萨玛林达市、邦塘市、库台Kartanegara区和东库台。
Analisis Spasial Persebaran Dan Pemetaan Kerawanan Daerah Titik Panas Di Kalimantan Timur Menggunakan Spatial Pattern Analysis Dan Flexibly Shaped Spatial Scan Statistic
The statistical method used to analyze spatial data and spatial statistics. The case study in this study is the average number of hotspots in East Kalimantan by Regency / City in 2016-2018. This study aims to analyze the presence or absence of spatial autocorrelation in the data on the number of hotspots, determine the distribution pattern of hotspots, as well as determine the level of vulnerability of potential areas for forest and land fires in East Kalimantan by Regency / City in 2016-2018. The method used to analyze spatial autocorrelation globally and determine the distribution patterns is the Moran Index. Local Indicator of Spatial Autocorrelation (LISA) to analyze spatial autocorrelation locally. Spatial autocorrelation analysis results globally using the Moran Index with α = 25% shows that there is a spatial autocorrelation in the average number of hotspots in East Kalimantan in 2016-2018. The distribution pattern of hotspots in East Kalimantan is the pattern of spread which shows that in 2016-2018 the hotspots spread in each district / city of East Kalimantan. Meanwhile, the results of the local analysis using LISA showed that there were spatial autocorrelations in several districts / cities in East Kalimantan. The method used to determine the level of vulnerability of potential forest and land fires is Flexibly Shaped Spatial Scan Statistics and LISA. The results showed that the regencies / cities included in the category of forest and land fire hazard were Samarinda City, Bontang City, Kutai Kartanegara District and East Kutai.
