摘要
利用遥感与GIS技术对日照港港口的多时相遥感数据进行了处理,提取了涉及港口环境的植被覆盖率、岸线资源等信息,同时对港口附近海域水体中的叶绿素和悬浮物等指标进行了定量反演。通过对处理结果的分析,对日照港的环境现状和近年来的环境质量变化给出评价并提出了一些在遥感与GIS技术应用中应注意的问题。遥感与GIS在日照港的应用表明,遥感与GIS技术可以快速、准确大面积地获取港口周边区域的环境信息,有效地弥补传统监测手段的不足。
The information about port environment, including vegetation cover, shoreline resource, etc. is extracted through the process of multi-temporal remote-sensing imagery data by RS and GIS techniques, and the indices of chlorophyll and suspended sediment of the water column around the port are estimated. By analysis of the results, the actuality and the change of Rizhao Port in the past few years are evaluated. The application of RS and GIS in Rizhao Port indicates that RS and GIS techniques, which can fast and accurately obtain the environment information of peripheral region of the port, makes up the deficiency of traditional monitoring tools, and provides a new source of data and assistant support for the environment monitoring and management of the port. At last, some problems about the application of RS and GIS are brought forward.
