The Northern Five Lakes are a series of narrow lakes distributed along the Grand Canal west to the hilly area of central Shandong Province， from north to south namely as the Anshan， the Mata， the Nanwang， the Shushan and the Machang Lakes. In the past 100 years， the five lakes have become silted up gradually. Now the main bodies of all the five lakes have vanished， except the remains of the Anshan and Machang Lakes. The authors collected multisource geospatial data covering the study area， including the map made in 1907， the aerial photographs taken in 1954， MSS image acquired in 1975， TM images acquired in 1987 and 2001 respectively and the SPOT5 XS image acquired in 2005. After the preprocessing step was conducted such as the geometric and radiometric correction， image mosaicking， the spatial distribution of the Northern Five Lakes were extracted for each period by means of visual interpretation and classification of the multisource data. According to the spatial distribution feature of the Northern Five Lakes in each period， the dying out magnitude， dying out speed and the dying out timing of the lakes were analyzed.
