Analysis of Coastal Environment in Yinggehai with Multi-Source Remote Sensing Images
摘要
Abstract
A large area of wetland in Yinggehai littoral zone in Hainan island is used as salt field, where the nature environment is obviously affected by intense human activities. In this paper, multi-source remote sensing images, including LiDAR data, SAR images, and multi-spectral images, are used to survey and analyses LUCC landscape of Yinggehai littoral zone. Retrieving accurate tidal line, microrelief DEM reconstruction and land cover classification are conducted. It can be found that the littoral zone is mainly covered with mangrove and lagoon wetland, which have been seriously damaged by human activities such as irrational exploitation of wetland or mudflat resources. It is also shown that there exists high ecological risk of soil and vegetation degradation. Based on microrelief DEM and LUCC retrieved from the remote sensing images, the relation among different types of land use is further discussed. The results would provide basic information and theoretical reference for wetland exploitation and protection. Some suggestions, including planning of mudflat use and restoring original wetland are brought out for the rational utilization of the resources.关键词
