| 摘 要： | 有一种观点认为,在黄河三角洲地区的莱州湾南岸平原,“古湖泊消亡的根本原因是气候变化”。通过查证资料,可以认为在黄河三角洲地区,从更新世以来的地质历史时期的气候变化、有文献记载的人类历史时期的气候变化以及近百年来有仪器记录的现代气候变化等三个层次上分析,均不存在湖泊消亡的气候条件。此外还列举了其他地区同时期湖泊消亡的气候条件,并将其与黄河三角洲地区进行比较,也说明黄河三角洲地区不存在湖泊消亡的气候条件。参照有关资料,在黄河三角洲地区,河道变迁频繁和人类活动加剧是湖泊消亡的根本原因。

| Abstract: | With regard to why lakes near the Yellow River Delta disappear, there goes such a viewpoint,i.e.on the south coast plain of th e Laizhou Bay, "climate change is the fundamental reason leading to the disappearance of ancie n t lakes." This paper suggests that in the Yellow River Delta, the climate condi t ions resulting in the disappearance of lakes from three aspects: climate changes in the geological time from the Pliocene, in the historical periods of several t housand years with historic records,and in other modern times of recent several hundred years with apparatus records,did not exist. The authors also list climate co nditions in the areas where lakes disappeard in the same period and compare them with those of the Yellow River Delta, and conclude that the climate conditions resulting in the disappearance of lakes do not exist in the Yellow R iver Delta. Fr equent changes of channel and increasing human activities in the Yellow River De lta Area are the fundamental factors. |
