摘　　要：应用地理信息系统GIS生成辽宁双台河口自然保护区景观分类图,并结合Fragstas软件计算了5个景观破碎化指数,对保护区破碎化程度进行分析和评价。结果表明:保护区整体破碎化指数为0.271,廊道密度指数为0.2km/km2,保护区破碎化程度较低。景观破碎化的主要原因是人为活动的干扰,如石油的开采。随着石油的开采,廊道密度的增加,将使破碎化程度加深。廊道景观的发展是景观破碎化的前提和动因。The landscape fragmentation was studied in Liaoning Shuangtai Estuary National Wetland Nature Reserve by using GIS and landscape analysis software Fragstats. And choosing five indexes （PD, FN, FS, MNN and CD） wcre used to analyze the landscape fragmentation .The results showed that the fragmentation index was 0.271, the corridor density was 0.20 km/km2, the extent of fragmentation in the study arca was relatively low. The main causc for landscape fragmentation was human disturbance such as oil cxploitation. With the exploitation of pctrolcum and the increase of corridor density, the fragmentation will bc deepened. The development of landscape corridors is the prcmisc and driving forcc of the landscape fragmentation.
