2024-11-16 30m resolution coastal aquaculture land distribution data set in Hangzhou Bay and its surrounding areas (2020) doi:10.57760/sciencedb.iga.00996 en a. Data content (data file/table name, observation index content included) This data includes the spatial distribution data set of coastal aquaculture pond land with 30m resolution in Hangzhou Bay and its surrounding areas, reflecting the distribution of coastal aquaculture pond types in Hangzhou Bay and its surrounding areas, and providing data support for coastal land use planning and coastal wetland protection in Hangzhou Bay and its surrounding areas. b. Construction purpose Hangzhou Bay Wetland is an important estuarine coastal wetland in China. Studies have been carried out on the shoreline change of Hangzhou Bay, the ecosystem service value of Hangzhou Bay Wetland and the coastal land use pattern of Hangzhou Bay, and the impact of human activities on the coastal wetland of Hangzhou Bay has been evaluated. The research shows that with the rapid development of economy, the coastal land space of Hangzhou Bay has changed dramatically, especially the land use mode of reclamation and aquaculture, which has a significant negative impact on the coastal wetland environment of Hangzhou Bay. Therefore, it is of great significance to objectively and accurately reveal the temporal and spatial distribution and change law of coastal aquaculture land in Hangzhou Bay for the protection of coastal wetlands in this area. c. Service object It can widely serve scientific researchers in coastal land use planning, ecological monitoring and other related disciplines. d. Time range of data 2020 e. Spatial range of data Hangzhou Bay and its surrounding areas f. Projection mode of data Projected Coordinate System：Krasovsky_1940_Albers Geographic Coordinate System：GCS_Krasovsky_1940 g.
