红树林范围和条件的变化可能会造成社会差距，即谁能够适应生态系统服务的变化，以及被认为对提供这些服务很重要的地方。分解式地理信息系统可以得出对生态系统服务场所重视程度的空间差异，但可以揭示红树林往往覆盖的小空间范围差异的分类研究尚不发达。使用混合方法（定量、定性和空间），评估了不同适应能力的家庭对生态系统服务及其提供场所的看法是否以及为什么不同。采用定量适应能力指标、人口和经济数据，对具有不同适应能力的三个家庭组进行了表征，海岸保护被认为对所有人都有好处，沉积物、生境供应和食物服务也经常与红树林有关。只有食物被不同的群体或多或少地识别出来。通过量化重叠的地方认为重要的提供这四种服务，为每组产生的空间热点，揭示了最大的差异，重要的食物的位置。采访表明，红树林地区特征的变化和适应能力的不同使一些家庭能够繁荣，而另一些家庭则陷入困境。我们考虑的适应能力，有助于缓和红树林的变化，谁可能是最受持续变化的影响。最后，我们确定了以当地人民不同的适应能力和多种生态系统服务需求为中心的恢复战略的前进方向。
Change in mangrove extent and condition has potential consequences for social disparity in terms of who can adapt to change in ecosystem services and places perceived important for providing them. Participatory GIS can elicit spatial variation in the importance attached to ecosystem service places, but disaggregated research that can reveal difference over the small spatial extents often covered by mangroves is underdeveloped. Using mixed-methods (quantitative, qualitative and spatial) in a rehabilitated mangrove system in Vietnam, this study assesses if and why perspectives about ecosystem services and their providing places vary among households with different capacities to adapt to mangrove change.Three household groups with different adaptive capacities were characterised using quantitative adaptive capacity indicators, demographic and economic data, and trajectory interviews spanning three decades: accumulating, coping and flexible households Coastal protection was identified as beneficial by all, and sediment, habitat provisioning and food services were also frequently associated with mangroves. Only food was identified significantly more or less by different groups. Spatial hotspots generated for each group by quantifying overlap in places perceived important for providing these four services, revealed greatest difference in locations important for food. Interviews indicated change in the characteristics of mangrove localities and different abilities to adapt to them enabled some households to prosper while others struggled. We consider adaptive capacities that helped temper mangrove change, and who might be most impacted by continuing change. We conclude by identifying ways forward for rehabilitation strategies centred on local people's differential adaptive capacity and multiple ecosystem service needs.
