【摘要】 通过对1988,1997和2005年3个时相Landsat卫星遥感数据的解译,得到了胶州湾北部大沽河口地区3个年份的土地利用变化状况,对比研究表明:该区域人工建筑物面积不断扩大,耕地面积不断减少;1997年以后加大了对未利用土地的开垦力度,使耕地面积减少速度相对降低,而河口自然湿地面积不断减少,主要转变为耕地和养殖池,湿地生态环境遭到破坏。考虑到大沽河口经济和自然方面的特殊属性,提出了缓和人与自然的矛盾、保护河口湿地的建议。更多还原

【Abstract】 Based on an analysis of three phases of remote sensing images(1988,1997 and 2005),we obtained information on the land use change of the Daguhe estuary: the area of infield decreased,and the area of construction increased especially after 1997,and most of which came from infield.After 1997 people started making use of large areas of unused land,then the infield area decreased slower.Most of the natural everglades became infields and breeding ponds,and the ecological entironment has been destroyed.And the everglade area of the Daguhe river is becoming smaller and smaller.In this paper we offer some suggestions to protect the entironment of the Daguhe estuary.更多还原
