摘　　要：在遥感和地理信息系统技术支持下，以1986年、1995年、2000年和2006年的TM影像为数据源，对三江平原别拉洪河不同尺度河岸带的土地利用格局进行分析，探讨人类活动对别拉洪河河岸带土地利用格局的影响。研究结果表明，在别拉洪河河岸带，耕地主要分布在距河道2km以外的河岸带；沼泽主要分布在距河道1km以内的河岸带；林地集中分布在距河道1～8km的河岸带。1986~2006年期间，在距河道1km的河岸带内，沼泽基本保持天然状态；在距河道1～8km河岸带内，人类活动对河岸带干扰较大；2000-2006年期间，别拉洪河河岸带内耕地面积的增加是以开垦沼泽、草地和砍伐森林为代价。近年来，别拉洪河河岸带内的耕地面积迅速增加，且向着河道方向不断拓展，严重危害了河岸带的湿地生态系统。因此，亟需加大对距别拉洪河河道1～2km河岸带内沼泽的保护力度。Supported by remote sensing and geography information systems, the land use pattems of riparian zones of Bielahong River in the Sanjiang Plain were analyzed using TM imageries in 1986, 1995, 2000 and 2006. The influence of human activities on the land use pattems of riparian zones of Bielahong River were in- vestigated too. The results showed that in the riparian zone of Bielahong River, farmlands were mainly distrib- uted beyond the distance of 2 km from the river, while marshes were within the riparian zone of 1 km from the river; forest lands were concentrated in the the riparian zones of 1-8 krn from the river. From 1986 to 2006, within the riparian zone of 1 km from the river marshes were relatively remained intact, but in the riparian zones of Bielahong River of 1-8 km from the river, the impact of human activities turned to be intensive. Dur- ing 2000-2006, the impact of human activities in the riparian zones was increasing and moving forwards to the river, by reclaiming marshes, grass lands and forest lands into farmlands. It harmed wetland ecosystem in the riparian zones of Bielahong River. More attention should be paid to the protection of riparian zones of Bielahong River of 1-2 km from the river.
