Abstract

With the continuous development of remote sensing technology, more diverse and detailed remote sensing data are widely used in the field of ecological environment monitoring, and at the same time, new data application and processing methods are born by virtue of its high resolution, high precision and high timeliness. In this regard, taking the coastal morphology of the Pearl River Estuary as the research object, according to the actual project requirements, this paper designs and develops a set of information platform for coastal surveying and mapping of the Pearl River Estuary based on WebGIS, so that users can quickly complete the loading, extraction, analysis and calculation of remote sensing data. The platform will focus on the extraction and analysis of Landsat, TM and ETM images from 1990 to 2020 in three directions, namely, the coastline of the Pearl River Estuary, the tidal flat area and the planned land use of the Pearl River Delta, so as to obtain the process, characteristics and laws of temporal and spatial changes and achieve the purpose of dynamic monitoring of the ecological environment in this area. The results show that the green space and water area in the Pearl River Estuary have been decreasing continuously in the past 30 years, and the trend of coastline change is obviously correlated with the trend of tidal flat change. It is necessary to strengthen the ability of ecological environment detection and risk prevention in the Pearl River Estuary and promote the comprehensive management of the Pearl River Estuary.
