Halpern et al. (Reports, 15 February 2008, p. 948) integrated spatial data on 17 drivers of change in the oceans to map the global distribution of human impact. Although fishery catches are a dominant driver, the data reflect activity while impacts occur at different space and time scales. Failure to account for this spatial disconnection could lead to potentially misleading conclusions.
哈尔彭等人(《报告》,2008年2月15日,第948页)整合了有关海洋17种变化驱动因素的空间数据,以绘制人类影响的全球分布图。尽管渔业捕捞是一个主要驱动因素,但这些数据反映的是活动情况,而影响发生在不同的空间和时间尺度上。未能考虑到这种空间上的脱节可能会导致潜在的误导性结论。
