摘要

摘要: 以详尽野外地质成果与实物证据首次发现湖内最新的地质事件——火山喷爆活动, 并划定该事件的时代、地点, 重新认识太湖地区、特别是自中生代以来的地质演变史、演变方式, 勾划出太湖湖盆形成的前提条件、内在因果原因.其后采用了本地区第四系变化、考古成果、古脊椎动物化石记录与古籍记载等丰富资料证明该区实际存在的沉降现象.沉降速率、成湖过程与成湖时代.最后以详实资料阐述了太湖及其周边未来演变规律以供地方规划与发展经济所利用.

Abstract: By showing exhaustive geological results and practical evidence, this article discovers the latest geological event in the lake for the first time-volcanic extrusion and explosion activity, and determines its date and location. The above-mentioned demonstration and the geological information accumulated by the writer for several decades will make it possible to re-understand the evolvement history and manner of the Taihu Lake area, especially after Mesozoic Era, and outline the pre-conditions and intrinsic causes for the lake-basin formation. The Quaternary system changes, archaeological achievements, fossil record of ancient spinal animals and recording on ancient books concerning this area all indicate that the lake actually experienced sinking phenomenon, sinking rate and lake formation. In the end, the author, by providing exhaustive information, expounds the future evolvement law of the Taihu Lake and its adjacent area for planning and developing of the local economy.
