چکیده
Wetland cities were proposed by the International Convention Organization for protection of urban wetlands. Few studies have performed land cover classifications internationally recognized wetland or explored what contribution classification results can make to establishment additional date. Based on Sentinel-1 and 2 data, this study used a 10-fold random forest method classify first six in China. A dataset, which had resolution 10 m included four types, was obtained area protected areas calculated. The showed that (1) accuracy good, overall above 90%, Kappa coefficient 0.88. (2) Cropland forested most common non-wetland coverage type accounted more than 20% 40% coverages, while water 2% coverages. From 2015 2020, built increased, cropland decreased significantly. (3) rate 6.68–37.56% 49.48–73.74% cities. relatively stable, inland (Yinchuan, Changde, Harbin Changshu) increased significantly, those coastal (Haikou Dongying) decreased, might be related change coastline. Therefore, we found wetlands these well protected. Land provide reference using remote sensing techniques monitor also supporting creation
