摘　　要：以高分辨率卫星遥感影像和部分航空图像为数据源,综合运用3S技术分析河口区土地利用总量及其变化量、土地利用变化速度、土地利用类型相互转换和土地利用程度等动态变化信息.结果表明,九龙江河口区土地利用类型主要以城乡工矿及居民用地、水田、养殖水面、园地、荒草地以及有林地为主;2003～2008年间,河口区主要土地利用方式发生了明显的变化,其中城乡工矿及居民用地、开发用地、园地面积分别增加了19.32、20.61、18.82 km2,水田、养殖水面、荒草地面积分别减少了15.29、4.23、17.03 km2,土地利用综合动态度为2.62%,土地利用变化速度较快;土地利用程度综合指数增加了10.27,土地利用程度增强.九龙江河口区城市化、开发建设和农业结构的调整增加了河口海域受非点源污染的可能性.Extractions from high resolution remote-sensed images and part of aerial photos of 2003,2007 and 2008 were combined with 3S（Remote Sensing,GIS,GPS） techniques to make a macroscopic and quantitative analysis of spatial-temporal dynamic change and its influence on the Jiulongjiang Estuary and its neighboring region in respect to the total area and its change,the change speed,the change style and the intensity of land use.The results showed six major land use types in the study area,including residential land,paddy field,aquaculture,orchard,glass and forest.2003～2008 witnessed a significant change in land use,with the built-up land,developing land and orchard noticeably increased 19.32,20.61,and 18.82 km2,respectively;meanwhile the paddy field,aquiculture and grass decreased 15.29,4.23,17.03 km2 respectively.LUCC Rt reached 2.62 %,and land use degree index increase 10.27;the speed of the land use change was relatively fast and the change intensity increased significantly.The urbanization,development,construction,and agricultural structure adjustment in Jiulongjiang Estuary and its neighboring region may increase the possibility of non-point pollution in Jiulongjiang Estuary.
