《水浒传》“八百里梁山泊”之说果真没有史料记载吗?

Are There Historical Records about Liangshan Water Margin of 800 Miles in the Novel of "The Water Margin"

北宋时的梁山泊真如施耐庵《水浒传》中说的那样有"方圆八百里"之广吗?今辞书虽有解释,但由于没有提供明确的史料根据,近年来学术界对这个问题有过讨论。央视《走遍中国》栏目曾于数年前进行过实地考察和采访,仍然没有找到宋元及以前明确的史料记载,因而也没有给出确切的答案。事实上,梁山泊在历史上不仅存在,而且其范围确有八百里,唐、宋、元时的文献中都有明确记载,宋、元诗人墨客的有关描写也反映出梁山泊的确是一个水面非常广阔的大湖,说明施耐庵之言不是虚构的。

Was Liangshan Water Margin in Song Dynasty in the novel really 800 miles wide？Although the dictionary has explanations about it,scholars do not fully agree due to lack of historical records. ＂Travel around China＂ of CCTV ever made on-the-spot investigation and interview years ago,but failed to obtain historical records or offer definite answer consequently.In fact,Liangshan Water Margin not only existed in history,but also covered 800 miles.Literatures in Tang,Song and Yuan Dynasties contained clear records.Description of poets in that age also showed that Liangshan Water Margin was a very broad lake,which means it was not invented by the author Shi Nai＇an.
