对生态系统服务的时空动态进行量化是一种新出现的方法，可用于通报和管理海洋环境中累积或竞争性活动之间的权衡。作为生态系统服务和效益的一个代理，我们使用75年的空间明确的时间序列量化和映射的捕获量和经济价值的加州商业渔业清除。从1931年到2005年，大约88%的捕获量来自于鳍鱼。然而，在过去的25年里，人们越来越依赖无脊椎动物的比例价值。历史渔获量的空间组织表明，物种组成因深度和纬度而有很大差异，对三个不同时期渔获量空间分布变化的评价表明，随着时间的推移，一些分类群体的渔获量地点发生了空间转移。对历史渔获量和价值的空间评估有利于海洋空间规划，为种群评估提供信息，提供了一个定量的评估工具。
Quantifying spatiotemporal dynamics of ecosystem services is an emerging approach for informing and managing trade-offs among cumulative or competing activities in marine environments. As one proxy for ecosystem services and benefits, we quantified and mapped catch and economic value of California commercial fisheries removals using a 75-year spatially explicit time series. From 1931 to 2005, approximately 88% of the catch was attributed to finfish. However, there has been an increasing reliance of proportional value from invertebrates over the last 25 years. The spatial organization of historical catches suggests species composition varies substantially by depth and latitude, and an evaluation of changes in the spatial distribution of catches in three different time periods suggests that spatial shifts in catch locations have occurred for some taxonomic groups over time. A spatial assessment of historical catches and value benefits marine spatial planning, informs stock assessments, provides a quantifica...
