Remote Sensing Investigation of Coastal Wetland Status in Liaodong Bay
摘要
Abstract
[Objective] To investigate the status of coastal wetland resources in Liaodong Bay and its driving factors.[Method] Based on Landsat-8 satellite data in 2014, TH 01-01 satellite data and ZY-3 satellite data in 2013, using remote sensing (RS) and geographic information system (GIS) technologies, combined with field investigation on coastal wetland, the types, area and spatial distribution of coastal wetland in Liaodong Bay were extracted.On this basis, the driving forces for the distribution of resources were analyzed by using the data of RS survey in 1986 and 2000.[Result] The area of coastal wetland in Liaodong Bay was 4.22×105 hm2.The areas of natural coastal wetland and artificial coastal wetland were 3.62×105 and 0.60×105 hm2 respectively, which took 86% and 14% of total area of coastal wetlands in Liaodong Bay respectively.Muddy tidal flats mainly distributed between the estuary of Xiaolinghe River and Xiwaizi Village of Tuanshan Street in Gaizhou City.Seepweed and reed mainly distributed between the estuary of Xiaolinghe River and the estuary of Liaohe River, showing the sporadic scattered distribution.Aquaculture pool, beach and ponds distributed in the whole research region.And breeding, pond, etc all have distribution in the region.Salt field mainly distributed in Changxing Island and its surrounding regions.The main driving factors that influenced the distribution of coastal wetland resources in Liaodong Bay were reclamation activities, erosion and sedimentation and composite actions.[Conclusion] The research results can provide data and decision-making basis for protection,reasonable development,utilization and management of coastal wetland resources.关键词
