Mapping ecosystem services is increasingly a focal area in ecosystem service research. Mapping services allows spatial variability in the benefits being received to be observed and incorporated in decision-making. Services vary in their biophysical supply as well as their economic value due to differences in ecological function and demand for the service. We map and present both vectors of change for seven ecosystem services for the state of Maryland. Economic value is estimated by observing previous instances of payment for increasing, or avoiding loss, to ecosystem services in Maryland or adjacent states. We find the economic value of ecosystem services from natural lands in Maryland to be significant, totaling $8 billion every year for seven non-market services. Storm-water mitigation is the largest service obtained from natural systems, totaling $3.1 billion annually, followed by wildlife habitat at $2.6 billion. Groundwater recharge, nitrogen removal, surface water protection, carbon sequestration, and air pollutant removal services are also valued and mapped. This work has several active or planned applications for the state’s prioritization of land acquisitions and ecological restoration funding.

绘制生态系统服务图越来越成为生态系统服务研究的重点领域。测绘服务使观察到的收益的空间可变性得以观察，并纳入决策过程。由于生态功能和服务需求的差异，服务的生物物理供应及其经济价值各不相同。我们绘制并提出了马里兰州七个生态系统服务的两种变化向量。经济价值是通过观察以前为增加或避免对马里兰州或邻近州的生态系统服务的损失而进行估算的。我们发现，来自马里兰州自然土地的生态系统服务的经济价值非常可观，每年为七项非市场服务共计80亿美元。缓解雨水是从自然系统获得的最大服务，每年总计31亿美元，其次是野生动植物栖息地26亿美元。还评估并绘制了地下水补给，氮去除，地表水保护，碳固存和空气污染物去除服务。这项工作有几个活跃的或计划中的应用程序，用于州优先考虑的土地收购和生态恢复资金。这项工作的结果可以在线查看-http://geodata.md.gov/greenprint/。
