【摘要】 遥感(RS)作为大面积宏观资源调查的重要手段,可以快速准确地查清河流的分布状况、自然特征和动态变化,同时可以定量分析河流流域中的自然环境和资源状况,是采集河流管理信息数据的重要方法。辽宁省首次采用卫星遥感及3S集成技术对全省河流分布状况、自然特征,以及河流流域中的生态环境状况进行普查。着重对遥感影像中辽河干流的自然形态,流域内土壤侵蚀类型、强度分布,以及土地利用状况等水土保持环境进行了分析与评价。更多还原

【Abstract】 Remote sensing as an important mean of investigation in large scale can rapidly make a through investigation of the distribution,natural features and dynamic change of rivers,meanwhile it can quantitatively analyze the natural environment and resources condition of these rivers,which is a major way of collecting information data of river management. Remote sensing and 3S technology was used to investigate the distribution,features and eco-environment of the rivers in Liaoning Province. The focus is on the form,soil erosion types,and intensity of the Liaohe River and land use.更多还原
