摘　　要：根据2010年海南石梅湾青皮林自然保护区的Google Earth卫星图片,选取石梅湾地区为研究对象,利用Photoshop7.0.1和Motic Images Plus 2.0ML图像处理分析软件,从景观总体特征、斑块面积、斑块周长、斑块数等方面分析该地区的景观格局,着重对保护站两侧的青皮林的破碎化程度进行分析和评价。结果表明:该区主要森林景观呈岛屿状分布,西片青皮林破碎化程度远大于东片青皮林;西片青皮林的林中空地面积比例大于东片;东片青皮林破碎化的主要原因是自然空地,西片青皮林破碎化的主要原因是坟地。Based on the satellite image of nature reserve for Vatica mangachapoi forest in Shimei bay from Google Earth in 2010, overall landscape features, patch area, patch perimeter, patch numbers, etc, were used to analyze the landscape pattern in the Shimei bay area. The paper also mainly focused on analyzing and evaluating the landscape fragmentation about Vatica mangachapoi forest on the both sides of the protection station for Vatica mangachapoi forest in order to provide valuable data for protecting the Vatica mangachapoi forest by means of the image processing and analysis softwares of Photoshop 7.0.1 and Motic Images Plus 2.0ML. The results showed that the main forest landscape of this area was island-like distribution; the fragmentation of Vatica mangachapoi forest on the western side was much serious than that in the eastern side; the proportion of the openings in the western side was more than that in the eastern side; the main reason to cause the fragmentation on Vatica mangachapoi forest in the eastern side was due to natural openings, and that in the western side was due to tombs.
