摘要
莲花池地区沉积相的研究 ,揭示了全新世以来至现今的环境特征。莲花池的面积虽不大 ,却曾经成为早期北京城的重要水源地。由于近几十年来气候干旱 ,人类过度的抽取地下水 ,以及人类活动的频繁和无序 ,致使莲花池在 2 0世纪的 90年代变成了排污池。 2 0世纪末北京市政府采取工程措施 ,对这一市重点文物进行了保护。但是 ,如何使其得到久远的维护 ,还需将其纳入北京市水循环的大系统之中。从沉积相古地理环境的角度 ,提出了五项建议。
A research of the sedimentary facies of Lianhua pound area, brought to light the features of environment from Holocene period till now ,though it's not large, but it's an important water area when Beijing City formed in the earliest period. That was a richer earth surface water and underground water. Due to the climate getting dry and man's activity getting more too in great drawing ground water. And made it has more pollution. Thus, till the late of twenty century, it became a place of drain off pollutant. At the end of century, Beijing government took an engineering to return to normal pound, Lianhua pound area become a very beautiful garden. But how can protect it forever? How can make the problem be settled once and for all? Thinking from the research of environment of sedimentary facies and restore ancient geography, in this area. How can make Lianhua pound bring into the whole of Beijing largest water system. There are five proposals to offer.
