中文摘要：基于3S技术及IAN景观格局分析软件,运用景观生态学的研究方法,以1977、1991、2000、2008年的4期雷州湾通明海红树林湿地卫星影像为主要数据源,以SRTM90 m DEM、Globcover 300 m及1∶10万土地利用数据为辅助数据,对研究区内湿地土地类型变化及景观空间格局的时空演变进行分析。研究结果表明:1977—1990年,人类干扰强烈,红树湿地被大面积破坏,同时其他林地及滩涂盐沼面积也大幅降低。这期间的红树林湿地景观以天然红树林景观为主,破碎度逐渐增加。1991—2000年,红树林转变率有所减少,红树林以大面积隔离保护及部分地区恢复为主,面积局部增加,红树景观由自然景观和人为景观共同构成。2001—2008年,研究区内虾塘养殖面积有所增加,局部破坏与整体保护并存,红树林面积局部减少,总体增加,呈现自然红树林景观及半自然半人工红树林景观并存的红树景观格局。

外文摘要：Based on 3S technology and IAN platform,the spatial and temporal changes of land use matrix and landscape patterns in Tongming-Hai of Leizhou Bay were analyzed in terms of satellite images in 1977,1991,2000 and 2008 and the auxiliary data from SRTM 90 m DEM,Globcover 300 m and 1∶100 thousand land-use map.The results showed that from 1977 to 1990,due to the strong disturbance of human beings,mangrove wetlands had been extensive damaged,and the other forest lands and tidal salt marsh areas were also greatly reduced.But the natural mangrove forest still dominated the landscape of the areas during this period.From 1991 to 2000,the change rate of mangrove was declined,and existed mainly in the large areas of isolated and protected mangrove together with the scattered and restored mangroves.The mangrove areas were partially increased,and composed of both the natural landscapes and the man-made landscape.From 2001 to 2008,the shrimp farming areas increased,the part damage and overall protection of mangrove were co-existed in the study areas.The mangrove landscape pattern was showed as co-existed landscape of the natural mangrove forest landscape and the semi-natural landscape.
