The application of remote sensing and GIS in the Jiulong River Watershed management

Abstract

遥感与GIS技术是水环境管理领域的重要技术手段,本研究综合运用定量遥感、GIS、景观生态学、数学统计等方法,对九龙江流域的水质变化进行遥感动态监测,并对该流域土地利用引起的的非点源污染与水质关系进行研究,对流域-海洋水环境信息综合管理系统进行了研究和设计。 利用Landsat遥感卫星对九龙江下游河段的叶绿素a和悬浮颗粒物浓度进行了年际变化分析及季节变化分析,发现较高的叶绿素a浓度主要出现在北溪浦南段(北8—北9)以及石龟头至北11段,叶绿素a在枯水期呈现浓度增大的趋势。高悬浮颗粒物浓度较易出现在龙津溪入口(北9—郭坑公路桥)河段,高悬浮颗粒物浓度季节主要发生在丰水季节。 九龙江流域不同坡度...Remote sensing and GIS techonology are the important tools for the water environment management. In this study, quantitative remote sense, GIS, landscape ecology, statistics methods were combined to study the water quality monitoring, non-point source pollutions from land use and integrated management system of basin-marine water environmental information. Based on Landsat TM retrieval results, ...学位:博士后院系专业:海洋与环境学院环境科学与工程系_环境科学学号:200917002
