摘要：Southeastern Australia lies within a temperate
zone characterized by mild, but
wet winters and hot summers with low
ratios of precipitation:evaporation (P/E).
Reconstructions of paleosalinity and water
level from numerous crater lakes (e.g. Lake
Keilambete) provide the means to monitor
long-term changes to P/E, and have
revealed a regional pattern of Holocene
climate change (Bowler, 1981; Chivas et al.,
1985; Gell, 1998; Jones et al., 1998). These
records witness humid conditions and
overfl owing lakes in the mid-Holocene, a
