历史上山东湖泊的变迁

ON HISTORICAL CHANGE OF LAKES IN SHANDONG PROVINCE

本文利用第四纪地质及古气候分析资料,论述山东的湖泊主要形成于中全新世气候最宜期。指出历史时期山东湖泊衰退的主要原因是:气候变干旱、森林破坏引起水土流失的加强,以及黄河迁徒、泛滥、淤积的影响。应用卫星影象的地貌分析和大量历史地理资料,对鲁西大野泽—梁山泊等湖的衰亡,南四湖的生成,以及鲁北与胶莱平原湖泊的衰亡过程作了扼要论述。

Based on the data of quaternary geotogy and palaeoclimate analysis the author shows that the lakes in Shandong were mainly formed in the Middle Hotocene Climatic Optimum. The major causes of the lake decline in Shandong in history are drying climate, severe soil erosion resulting from the forest destruction and the effects of the Yellow River deposits and course changes. On the basis of geomorphological analysis on the Landsat images and the data of historical geography, discussions are made on the disapearance of Da Ye Ze-Liang Shan Bo Lake and the formation of Nan-Si Lake in the western Shandong, and the decline of lakes in the northern Shandong and on the Jiao Lai Plain.
