原始语种摘要: Abstract(#br)Over the past 100 years, Australia has experienced pronounced changes in rainfall patterns, which in south‐western Australia (SWAU) has resulted in both a >50% decrease of runoff since 1975 and effects on vegetation health. Resolving the dynamics of vegetation and climate is a prerequisite for predicting the response of vegetation to future climates and carbon mitigation objectives. With multi‐resource vegetation indices (VIs; normalized difference vegetation index and leaf area index) and gridded climate data, this paper examines vegetation dynamics and sensitivity to rainfall change on the Australian continent for the past long drought period (2002–2010). We found that rainfall and VIs declined across 90% and 80% of the whole continent, respectively, compared to the...
