1Integrating modelling and remote sensing to identify ecosystem performance anomalies in the boreal forest,Yukon River Basin,Alaska显示文摘High-latitude ecosystems are exposed to more pronounced warming effects than other parts of the globe.We develop a technique to monitor ecological changes in a way that distinguishes climate influences from disturbances.In this study,we account for climatic influences on Alaskan boreal forest performance with a datadriven model.We defined ecosystem performance anomalies(EPA)using the residuals of the model and made annual maps of EPA.Most areas(88%)did not have anomalous ecosystem performance for at least 6 of 8 years between 1996 and 2004.Areas with underperforming EPA(10%)often indicate areas associated with recent fires and areas of possible insect infestation or drying soil related to permafrost degradation.Overperforming areas(2%)occurred in older fire recovery areas where increased deciduous vegetation components are expected.The EPA measure was validated with composite burn index data and Landsat vegetation indices near and within burned areas.B.K.Wylie L.Zhang N.Bliss L.Ji L.L.Tieszen W.M.Jolly 2008International Journal of Digital Earth2008,1,2:2
