红树林海向扩张与地貌特征交互查询工具Mangrove Seaward Expansion and Geomorphic Characteristics Explorer
本工具使用了全球红树林地貌分类数据（Worthington et al., 2020）提供的 3,983 个地貌单元，这些单元分属三角洲、河口、开放海岸和潟湖四类地貌。对于每类地貌，我们分别依据潮滩面积的年际增量和长期平均红树林面积的分位数划分区间，并根据历史观测统计各区间次年发生红树林海向扩张的概率。您可以在地图上点击关注的地貌单元，输入该单元的新增潮滩面积进行查询；也可以自行选择地貌类型，并输入研究区域的长期平均红树林面积和某年新增潮滩面积，查询相应条件下的次年红树林海向扩张概率。This tool uses 3,983 geomorphic units from the global biophysical typology of mangroves (Worthington et al., 2020), spanning four geomorphic types: deltas, estuaries, open coasts, and lagoons. For each type, we define quantile intervals separately for the year-on-year increase in tidal flat area and long-term mean mangrove area, then use historical observations to calculate the probability of mangrove seaward expansion in the following year for each combination. You can click a geomorphic unit of interest on the map and enter its tidal flat gain to query the result; alternatively, select a geomorphic type and enter your study area's long-term mean mangrove area and tidal flat gain in a given year to look up the next-year probability of mangrove seaward expansion under those conditions.

面积以地貌单元为统计范围。某年新增潮滩面积须大于 0。Areas refer to a geomorphic unit. Tidal flat gain in one year must be greater than 0.

各地貌类型的总体海向扩张概率 Overall seaward expansion probability by geomorphic type
这里展示四种地貌类型中，某年潮滩面积增加后，次年红树林发生海向扩张的总体概率。每个百分比均由该类型发生扩张的单元—年份样本数除以潮滩面积增加且次年结果可观测的样本总数得到，不再按面积分位数区间细分。This section shows the overall probability of mangrove seaward expansion in the year after tidal flat area increases, separately for each of the four geomorphic types. Each percentage is the number of unit-year observations with expansion divided by all observations of that type with tidal flat gain and an observable next-year outcome, without further division into area quantiles.
