摘　　要：采用稳定性评价模型、克里金插值法和箱线图法,对海南省东方市2005年生态景观格局稳定性进行评价分析。结果表明:海南省东方市生态环境整体态势良好,大部分地区达到稳定或一般稳定状况。其中稳定区集中分布于西南部,主要为斑块较完整的乔木林地,林种以天然阔叶混交林为主;中度稳定区主要分布于东方市的陀兴水库和大广坝水库周边;一般稳定区主要分布于感恩河、南清河和大安水库附近,以乔木林地和农用地为主,且伴有水域零星分布;一般不稳定区主要分布城镇和村庄,以建设用地和其他用地为主,受人类活动的影响;十分不稳定区主要分布于四更镇、新龙镇、抱板镇和东方市市区,以建设用地和其他用地为主。生态景观格局稳定性研究为海南省东方市生态景观的可持续发展提供了理论依据。Based on stability evaluation model, Kriging, box plot method, this study landscape pattern analysis of stability evaluation of Dongfang city, Hainan province. The results showed that： The ecological environment of the study area is in good condition, and the most of the area is stable. The landscape stability region are mainly woodland, forest and mixed forest distributed in the southwest; the surrounding medium stable region mainly distributed in the eastern city of Tuoxing reservoir and Daguangba reservoir; General stable area mainly distributed in the near of Gangen River, Nanqing River and Daan reservoir, the mainly in the area mainly of woodland and agricultural land; very unstable area mainly distributed in Sigen town, Xinlongtown, and Baoban town and the Dongfan city. The study provides a scientific basis of decision-making for the ecological environment the sustainable development and stability in Dongfang of Hainan province.
