However, if we blindly pursue economic development and ignore environmental protection, it will cause serious damage to the global climatic conditions and ecological structure. To avoid such tragedies, relevant government and non-government agencies need to be able to effectively monitor land use and land cover changes. In order to achieve effective resource management and plan or adapt land use plans. Remote sensing data is currently the fastest method to obtain a large amount of land use and land cover data. Among the various remote sensing data, satellite images are often used by researchers to derive land cover data and doing change detection due to their advantages of high time resolution and low cost. source. And among the common methods for discussing land cover change with satellite images, the classification-based approach is the method most used by researchers because it can fully discuss the relationship between categories. Previous studies are mostly only comparing the differences in land cover maps between two time periods when discussing land cover change. However, this method does not fully utilize the time series characteristics of multi-period land cover data. Therefore, this study attempts to combine the LICD and the Mann-Kendall trend test to propose a hot spot analysis algorithm for spatial and temporal changes suitable for categorical data. And this algorithm is used to analyze the land cover changes in the Xincheng and Marseille areas, Suao Town, Yilan County from 2006 to 2016. The research results show that this algorithm can present the temporal and spatial aggregation trends of various categories from the multi-period land cover category data. The results of such analysis can assist urban planners and relevant government agencies with useful information in planning.土地利用/土地覆蓋類別空間資料空間統計多時期變化偵測Land use/ Land coverCategorical spatial dataSpatial statisticsLocal indicator for categorical data (LICD)Mann-Kendall trend testMultitemporalChange detectionetd
