广西人类活动强度时空变化及其经济驱动分析

Analysis on Temporal and Spatial Variation of Human Activity Intensity and Its Economic Driving Force in Guangxi

研究基于土地覆被数据和建设用地当量折算方法,探究1980-2018年广西人类活动强度时空变化及经济驱动因素。结果表明:(1)1980-2018年间,广西城乡/工矿/居民用地面积呈大幅度增加趋势,耕地、林地、草地均呈减少趋势;(2)广西人类活动强度变化以2010年为界,前期增长缓慢,后期增长迅速,整个研究时段均有显著的空间集聚特征;(3)农林牧渔业是广西人类活动强度变化的首要产业推动力,其次是建筑业、工业。

Based on the land cover data and the equivalent conversion method of construction land,this study explores the temporal and spatial changes of human activity intensity and economic driving factors in Guangxi from 1980 to 2018.The results show that:(1)From 1980 to 2018,the area of urban and rural/industrial and mining/residential land in Guangxi increased significantly,and the cultivated land,forest land and grassland decreased;(2)The change of human activity intensity in Guangxi is bounded by 2010,with slow growth in the early stage and rapid growth in the later stage.There are significant spatial agglomeration characteristics in the whole research period;(3)Agriculture,forestry,animal husbandry and fishery are the primary industrial driving force for the change of human activity intensity in Guangxi,followed by construction and industry.
