摘　　要：以三亚市海棠区为例,运用ArcGIS和ENVI软件对2002—2022年遥感影像进行处理,探索20年来土地利用变化趋势;计算人均生态足迹和生态承载力,分析土地利用变化产生的生态环境效应。结果表明:海棠区的土地利用状况发生了巨大的变化,其中变化较为显著的是耕地、林地、建设用地;耕地和林地的流向主要是建设用地。这一时期海棠区高速发展,人类活动对土地利用的影响加剧。海棠区土地利用生态效应不宜乐观,海棠区生态足迹与生态承载力供给呈反方向发展趋势,海棠区人口对自然资源的利用已逐渐接近自然生态系统的生态承载力饱和范围。Taking Haitang District of Sanya City as an example,ArcGIS and ENVI software were used to process remote sensing images from 2002 to 2022,explore the change trend of land use over the past 20 years,calculate per capita ecological footprint and ecological carrying capacity,and analyze the ecological environmental effects generated by land use changes.The results showed that the land use status in Haitang District had undergone great changes,among which the most significant changes were cultivated land,forest land and construction land.The decrease of cultivated land and forest land was mainly for construction land.The rapid development of Haitang District in this period reflected the intensification of human activities on land use.The ecological effect of land use in Haitang District should not be optimistic.The ecological footprint and ecological carrying capacity supply in Haitang District developed in the opposite direction.The utilization of natural resources by population in Haitang District gradually approached the saturation range of ecological carrying capacity of natural ecosystem.
