Based on remote sensing images from 2020 to 2021 and ground surveys, this study aims to analyze the categories, quantities, and spatial distribution of small and micro wetland resources with Fengxian District, Shanghai. The total area of small and micro wetlands in Fengxian District is 713.58 hm2, including reservoirs, canals/river, and aquaculture farms/planting ponds. Among them, the area of aquaculture farms/planting ponds is 374.3 hm2, the maximum amount, accounting for 52.54% of the total area. In the patchy structure, as the plaque size increased, the proportion of quantity and area of micro wetland followed a polynomial trend, mainly with the plaque size of 1～4 hm2. Each town has its own emphasis on the quantity and distribution of small and micro wetlands. The higher the urbanization rate, the smaller the area of small and micro wetlands. Based on the survey results, local protection strategies are proposed from four key aspects: optimizing the living environment, enhancing the rural environment, developing ecotourism, and conserving biodiversity. These suggestions can support the protection and utilization of regional micro and small wetlands.
