基于多源空间数据的鲁中北五湖近100年变化分析

北五湖系鲁中黄河以南自北向南分布的一系列湖泊，分别为安山湖、马踏湖、南旺湖、蜀山湖和马场湖。近100年来，北五湖陆续淤废，目前，除安山湖、马场湖尚有残存外，其他诸湖悉数消亡。作者收集了北五湖地区1907年测绘地图、成像于1954年的航片、成像于1975年的MSS遥感影像、分别成像于1987年、2001年的TM遥感影像以及成像于2005年的SPOT5 XS遥感影像等6个时段的数据。对其进行了几何纠正与配准、图像镶嵌等预处理，通过目视解译和遥感分类等手段提取了该地区6个时期的北五湖空间分布数据。根据北五湖6个不同时段的空间展布特征，分析了近100年以来北五湖消亡的幅度、速度和时间等特征，并在此基础上初步探讨了北五湖消亡的原因。

Change analyses of Northern Five Lakes in central Shandong Province in past 100 years based on multiple spatial data

 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 multi source geo spatial 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 multi source 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.
