Article Synopsis
- Coastal wetlands, consisting of tidal flats and coastal vegetation, are crucial for wildlife and ecosystem health, but detailed maps of these areas in China have been lacking.
- This study used nearly 44,528 Landsat images and Google Earth Engine to create annual maps of coastal tidal flats in eastern China from 1986 to 2016, revealing a total area of about 731,170 hectares in 2016.
- The analysis identified three key periods of change in coastal tidal flats: stability from 1986-1992, growth from 1993-2001, and decline from 2002-2016, providing valuable data for sustainable coastal management.
Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and quantify these effects. In this study, an algorithm was developed to map forests in 2010, with the use of structure and biomass information from the Advanced Land Observation System (ALOS) Phased Array L-band Synthetic Aperture Radar (PALSAR) mosaic dataset and the phenological information from MODerate Resolution Imaging Spectroradiometer (MOD13Q1 and MOD09A1) products.
